DESCRIPTION 1.1. Overview The 92HDW74D is a high fidelity, 8-channel audio codec compatible with the Intel High Definition (HD) Audio Interface. The 92HDW74D codec provides high quality, HD Audio capability to desktop and multi-media notebook. The 92HDW74D is designed to meet or exceed premium logo requirements for Microsoft's Windows Logo Program (WLP) 3.09 and revisions 4 as indicated in WLP 3.09. The 92HDW74D provides stereo 24-bit, full duplex resolution supporting sample rates up to 192kHz by the DAC and ADC. 92HDW74D SPDIF outputs support sample rates of 192kHz, 176.4kHz, 96kHz, 88.2kHz, 48kHz, and 44.1kHz. 92HDW74D SPDIF input supports sample rates of 96kHz, 88.2kHz, 48kHz, and 44.1kHz. Additional sample rates are supported by the driver software. The 92HDW74D supports a wide range of desktop and consumer 8 channel configurations. The 2 independent SPDIF output interfaces provides connectivity to Consumer Electronic equipment like Dolby Digital decoders, powered speakers, mini disk drives or to a home entertainment system. Simultaneous HDMI and SPDIF output is possible. MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the 92HDW74D has 8 General Purpose I/O (GPIO). The port presence detect capabilities allow the codecs to detect when audio devices are connected to the codec. Load impedance sensing helps identify attached peripherals for easy set-up and a better user experience. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion and removal for protection of notebook speakers. The 92HDW74D operates with a 3.3V digital supply and either 3.3V, or 5V analog supply. It can also work with 1.5V and 3.3V HDA signaling; the correct signalling level is selected dynamically based on the power supply voltage on the DVDD-IO pin. The 92HDW74D is available in a 48-pin LQFP Environmental (ROHS) package. Additional products with the same features as the 92HDW74D are the 10-channel 92HDW74E and the 6-channel 92HDW74C. 1.2.

PC AUDIO Detailed Description 1.4.1. Port Functionality Multi-function (Input / output) ports allow for the highest possible flexibility. 8 bi-directional ports (3 headphone capable) support a wide variety of consumer desktop and mobile system use models.

Port Functionality Note1: 40dB boost requires using the IDT driver. When the 40dB mic boost feature is enabled, additional gain increases greater than 6dB may result in significant audio quality degradation of the microphone audio input. In particular, when the 40dB MIC boost is active, the SNR, THD+N and DC offset will significantly degrade regardless of the input signal level. 1.4.2. Port Characteristics Universal (Bi-directional) jacks are supported on all ports except the CD input. Ports A, B, and D are designed to drive a set of 32 ohm (nominal) headphones or a 10K (nominal) load with on board shunt resistance as low as 20K ohms (typical - used to maintain coupling CAP bias.) Line Level outputs are intended to drive an external 10K speaker load (nominal) and an on board shunt resistor of 20K-47K (nominal). However, applications may support load impedances of 5K ohms and above. Input ports are 47K (nominal) at the pin. DAC full scale output and intended full scale input levels are 1V rms. Line output ports and Headphone output ports on 92HDW74D may be configured for +3dBV full scale output levels by using a vendor specific verb. Output ports are always on to prevent pops/clicks associated with charging and discharging output coupling capacitors. This maintains proper bias on output coupling caps even in D3 as long as AVDD is available. Unused ports should be left unconnected. When updating existing designs to use the 92HDW74D, ensure that there are no conflicts between the output ports on 92HDW74D and existing circuitry. 13 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT AFG Power State PC AUDIO Input Enable Output Enable Mute Port Behavior 1 1 - Not allowed.

D0-D2 D3 Table 2. Analog I/O Port Behavior 1.4.3. Jack Detect Plugs inserted to a jack on Ports A, B, C, & D are detected using SENSE_A. Plugs inserted to a jack on Ports E, F, G, and H are detected using SENSE_B. The following table summarizes the proper resistor tolerances for different analog supply voltages. SENSE_C, is different from SENSE_A and SENSE_B. Because SENSE_C only determines the presence of a plug for the CD port (port I), SENSE_C is a simple digital input pin referenced to the analog supply. An internal pull-up resistor is provided. No external resistors are needed (jack switch shorts to ground when a plug is inserted.) If external components are added, or if the pin is driven by a logic gate, care should be taken to ensure that the pin voltage is above 70% of AVDD when no plug is in the jack and less than 30% AVDD when a plug is inserted AVdd Nominal Voltage (+/- 5%) Resistor Tolerance SENSE_A (If port D used) Resistor Tolerance SENSE_A (If port D is not used) Resistor Tolerance SENSE_B (If port H used) Resistor Tolerance SENSE_B (If port H is not used) 5V 1% 1% 1% 1% 4.75V 1% 1% 1% 1% 4V 0.50% 1% 0.50% 1% 3.3V 0.10% 1% 0.10% 1% Table 3: SENSE Resistor Tolerance See reference design for more information on Jack Detect implementation. 1.4.4. SPDIF Output All SPDIF Outputs can operate at 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4KHz, and 192KHz as defined in the Intel High Definition Audio Specification with resolutions up to 24 bits. This insures compatibility with all consumer audio gear and allows for convenient integration into home theater systems and media center PCs. A second independant SPDIF Output is provided as an option for WLP compliant HDMI and SPDIF outputs. Its function is identical to the primary SPDIF output. 14 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT PC AUDIO Note: Peak to peak jitter is currently limited to less than 4.5nS (half of the internal master clock cycle) which does not meet the IEC-60958-3 0.05UI requirement at 192KHz. The two SPDIF ouput converters can not be aligned in phase with the DACs. Even when attached to the same stream, the two SPDIF output converters may be misaligned with respect to their frame boundaries. SPDIF Outputs on pins 48 and 40 are outlined in tables below.

A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs. Advanced features such as record-slot-select and SPDIF_IN routing to the DAC allow for simultaneous record and play. 1.4.6. Analog Mixer An analog mixer is available on the 92HDW74D. The mixer supports independent gain (-34.5 to +12dB in 1.5dB steps) on each input as well as independent mutes on each input. A master volume follows mixing and provides gain from -46.5dB to 0dB in 1.5dB steps. The following inputs are available: * CD * Analog PC_Beep * Inport0_Mux * Inport1_Mux * Inport2_Mux * Inport3_mux 16 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 1.4.7. PC AUDIO Input Multiplexers 92HDW74D implements 4 port input multiplexers. These multiplexers allow a preselection of one of four possible inputs: Inport0_Mux Inport1_Mux Inport2_Mux Inport3_mux Port A Port A Port B DAC 0 Port B Port E Port C DAC 1 Port D Port G Port G DAC 2 Port F Port H Port H DAC 3 Table 6. Input Multiplexers 1.4.8. ADC Multiplexers 92HDW74D implements 2 ADC input multiplexers. These multiplexers incorporate the ADC record gain function (0 to +22.5dB gain in 1.5dB steps) as an output amp and allow a preselection of one of 12 possible inputs: 1.4.9. * DMIC 0 * DMIC 1 * Mixer output * CD input * Ports A - H Power Management The HD Audio specification defines power states, power state widgets, and power state verbs. Power management is implemented at several levels. The Audio Function Group (AFG) and all converter widgets support the power state verb F05/705 (as well as the pin widget associated with pin 47.) Converter widgets are active in D0 and inactive in D1-D3. The following table describes what functionality is active in each power state supported by the AFG.

Function state vs. AFG power state 1.No DAC or ADC streams are active. Analog mixing and loop thru are supported. 2.VAG is kept active when ports are disabled or in D2/D3. Ports may be powered down using vendor specific verbs. 3.VAG is always ramped up and down gradually, except in the case of a sudden power removal. VAG is active in D2/D3 but in a low power state. 4. BITCLK must be active and both AVDD and DVDD must be available for Port Sense to operate. 5.Vendor specific bit for Ref Top controls VAG generator, Bandgap Reference, and Reference bias generator. Place part into D3 and power down all ports (using vendor specific verbs) before powering down Ref Top. 6.Obviously not active if BITCLK is not running (Controller in D3). 1.4.9.1. AFG D0 The AFG D0 state is the active state for the device. All functions are active if their power state (if they support power management at their node level) has been set to D0. 1.4.9.2. AFG D1 D1 is a lower power mode where all converter widgets are disabled. Analog mixer and port functions are active. 1.4.9.3. AFG D2 The D2 state further reduces power by disabling the mixer and port functions. The port amplifiers and internal references remain active to keep port coupling caps charged and the system ready for a quick resume to either the D1 or D0 state. 1.4.9.4. AFG D3 The D3-default state is available for HD Audio compliance. All converters are shut down. Port amplifiers and references are active but in a low power state to prevent pops. Resume times may be longer than those from D2, but still very fast to meet Intel low power goals. The traditional use for D3 was as a transitional state before power was removed (D3 cold) before the system entered into standby, hibernate, or shut-down. To conserve power, Intel now promotes using D3 whenever there are no active streams or other activity that requires the part to consume full power. The system remains in S0 during this time.

To enable this use model, the CODEC must resume within 10mS and not pop. The default power state for the Audio Function Group after reset is D3-default 1.4.9.5. AFG D3 and vendor specific verbs The programmable values, exposed via vendor-specific settings, are under the IDT Device Driver control for further power reduction. 1.4.10. Low-voltage HDA Signaling The 92HDW74D is compatible with either 1.5V or 3.3V HDA bus signaling; the voltage selection is done dynamically based on the input voltage of DVDD_IO. When in 1.5V mode, the 92HDW74D can correctly decode BITCLK, SYNC, RESET# and SDO as they operate at 1.5V; additionally it will drive SDI and SDO at 1.5V. None of the GPIOs are affected, as they always function at their nominal voltage (DVDD or AVDD). 1.4.11. Multi-channel capture The capability to assign multiple ADC "Input Converters" to the same stream is supported to meet the microphone array requirements of Vista and future operating systems. Single converter streams are still supported and is done by assigning unique non zero Stream IDs to each converter. All capture devices (ADCs 0 and 1) may be used to create a multi-channel input stream. There are no restrictions regarding digital microphones. However, the SPDIF input can not be used with an ADC to create a 4-channel stream. SPDIF_In only supports stereo capture. The ADC Converters can be associated with a single stream as long as the sample rate and the bits per sample are the same. The assignment of converter to channel is done using the "CnvtrID" widget and is restricted to even values. The ADC converters will always put out a stereo sample and therefore require 2 channels per converter. The stream will not be generated unless all entries for the targeted converters are set identically, and the total number of assigned converter channels matches the value in the NmbrChan field. These are listed the "Multi-Converter Stream Critical Entries" table. An example of a 4 Channel Steam with ADC0 supplying channels 0&1 and ADC1 supplying channels 2&3 is shown below. A 4 Channel stream can be created by assigning the same non-zero stream id "Strm= N" to both ADC0 and ADC1. The sample rates must be set the same and the number of channels must be set to 4 channels "NmbrChan = 0011".

Table 9: Multi-Converter Stream Critical Entries. 1.4.12. EAPD The EAPD pin (pin 47) also supports SPDIF_In and GPIO functions. The pin defaults to EAPD after power on reset and will remain in EAPD mode until either GPIO is enabled for pin 47 or the port I/O is enabled to support SPDIF. Although named External Amplifier Power Down (EAPD) by the HD Audio specification, this pin operates as an external amplifier power up signal. The EAPD value is reflected on the EAPD pin; a 1 causes the external amplifier to power up, and a 0 causes it to power down. When the EAPD value = 1, the EAPD pin must be placed in a state appropriate to the current power state of the associated Pin Widget even though the EAPD value may remain 1. The default state of this pin is 0 (driving low) and a Pull-down prevents the line from floating high when the part is in reset. 21 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT AFG Power State RESET# GPIO Enable Input Enable PC AUDIO EAPD Power State Pin Behavior Asserted (Low) - - - Hi-Z (internal pull-down enabled) immediately after power on, otherwise the previous state is retained until the rising edge of RESET# De-Asserted (High) Enabled - - Active - Pin reflects GPIO0 configuration (internal pull-up enabled) De-Asserted (High) Disabled Enabled - Active - Pin is SPDIF_In De-Asserted (High) Disabled Disabled D0-D1 Active - Pin drives the value of the EAPD bit (internal pull-down enabled) De-Asserted (High) Disabled Disabled D2-D3 Hi-Z (internal pull-down enabled) De-Asserted (High) Disabled Enabled - Inactive - Pin configured as input, but SPDIF_In idle.

EAPD 1.4.13. Digital Microphone Support The digital microphone interface permits connection of a digital microphone(s) to the CODEC via the DMIC0, DMIC1, and DMIC_CLK 3-pin interface. The DMIC0 and DMIC1 signals are inputs that carry individual channels of digital Mic data to the ADC. In the event that a single microphone is used, the data is ported to both ADC channels. The DMIC_CLK output is controllable from 4.704Mhz, 3.528Mhz, 2.352Mhz, 1.176Mhz and is synchronous to the 24Mhz internal clock. The default frequency is 2.352Mhz. The two DMIC data inputs are reported as two stereo input pin widgets that incorporate a boost amplifier. The pin widgets are shown connected to the ADCs through the same multiplexors as the analog ports. Although the internal implementation is different between the analog ports and the digital microphones, the functionality is the same. In most cases, the default values for the DMIC clock rate and data sample phase will be appropriate and an audio driver will be able to configure and use the digital microphones exactly like an analog microphone. 92HDW74D supports the following digital microphone configurations: 23 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT PC AUDIO Digital Mics Data Sample ADC Conn.

PC AUDIO PC-Beep 92HDW74D supports both analog and digital PC_Beep functions. 1.4.14.1. Analog PC-Beep 92HDW74D does not support automatic routing of the PC_Beep pin to all outputs when the link is in reset. Analog PC-Beep may be supported during Link Reset if the mixer is manually configured for pass-thru. Otherwise, Reset# must be high and Bit_Clk active. The default values for the vendor specific verb (7EE/FEE in AFG) associated with Analog PC-Beep are: * Enable = 0h (Analog PC-Beep disabled - mute) * volume = 3h (0dB) Analog PC-Beep is supported in D3, but may be attenuated or distorted depending on the loadimpedance on the port. Line outputs can drive 10K ohm loads in D3 at 1Vrms, but will be current limited when driving lower impedance loads. Enabling or disabling analog PC-Beep may cause a click or pop sound. 1.4.14.2. Digital PC-Beep This block uses an 8-bit divider value to generate the PC beep from the 48kHz Azalia sync pulse. The digital PC_Beep block generates the beep tone on all Pin Complexes that are currently configured as outputs. The HD Audio spec states that the beep tone frequency = (48kHz HD Audio SYNC rate) / (4*Divider), producing tones from 47 Hz to 12 kHz (logarithmic scale). Other audio sources are disabled when digital PC_Beep is active. It should be noted that digital PC Beep is disabled if the divider = 00h. 1.4.15. Headphone Drivers This product implements a +3dBV output option on headphone capable ports. (HP output and line output levels are defined as 1Vrms at this time with an option to enable +3dBV FSOV using a vendor specific verb.) The Microsoft Windows Logo Program allows up to the equivalent of 100ohms in series. However, an output level of +3dBV at the pin is required to support 300mV at the jack with a 32ohm load and 1V with a 320 ohm load. Microsoft allows device and system manufactures to limit output voltages to address EU safety requirements. (WLP 3.09 - please refer to the latest Windows Logo Program requirements from Microsoft.) 92HDW74D, however, requires external components (series resistors) to limit the output voltage to 150mV with a 32 ohm load or secure software limiting by restricting DAC and mixer gain ranges. Although 3 Headphone amplifiers are present, only two may be used simultaneously. Performance will degrade when driving more than one set of headphones. Only one set of headphones (32 ohm nominal) may be connected to a headphone capable port. 28 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 1.4.16.

To determine which function is actually enabled on the 2 pins, the order of precedence is followed: 1. If the GPIOs are enabled, they override both Volume Control and Digital Mics 2. If the GPIOs are not enabled through the AFG, then at reset, the Volume control is enabled with the weak pull-up. 3. If BIOS or other software application enables either Digital Microphones inputs through the Configuration Default Register, the Volume is disconnected and the pull-ups are disconnected with the weak pull-downs enabled. 1.4.16.3. VRefOut/GPIO Selection Two functions are available on pins 29, 31, and 37. To determine which function is actually enabled, the order of precedence is followed: 1. If the GPIOx function is enabled, it overrides VRefOut-X 2. If the GPIO function is not enabled through the AFG, then the VrefOut function is enabled and in its default state. 3. If using a VrefOut pin as GPIO, make sure to incorporate a 10K ohm external pull-up to AVDD to prevent the pin from floating in GPI mode and to allow proper operation in open-drain GPO mode. 29 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 1.4.17. PC AUDIO External Volume Control 92HDW74D incorporates a 2-pin volume control interface. Volume up, down, and mute functions are easily implemented using 2 push-button switches. The CODEC provides internal pull-up resistors simplifying external CODEC circuitry. Also, repeat and direct modes of operation add flexibility to the interface. The typical usage model is for front panel master volume buttons on an entertainment PC, or case mounted hardware volume control for mobile platforms. 1.4.17.1. Theory of Operation The codec monitors the volume up/down inputs for a change of state from high to low, and waits for the inputs to settle. If the inputs have not settled by the end of the de-bounce period, then the value at the end of the period is used. A 0 (low voltage) on the Down pin will decrement the volume register, while a 0 on the Up pin will increment the volume register. If both inputs are 0 at the same time, then the volume register will be set to its lowest value (mute). Pressing Up, Down, or both buttons at the same time when the volume control interface is in mute mode, will cause the part to un-mute. The de-bounce / repeat rate is selectable from 2.5Hz to 20Hz in 2.5Hz increments using the Volume Knob VCSR0 verb (FE0) Rate bits (bits 2:0). This value is used for both de-bounce and repeat rates. The de-bounce period is the time that the CODEC waits for the inputs to settle, and the repeat rate is the rate at which the CODEC will increment/decrement the volume if a volume button is pushed and held. When a falling edge is detected on either one of the volume control pins, the codec will wait for (1/Rate) seconds for the input to settle. If the Continuous bit is set in the Volume Knob VCSR0 verb (bit 3), then the codec will wait for the de-bounce period to expire then repeatedly increment or decrement the volume register at the rate specified in the Rate bits until the button is released. 1.4.17.2. * Modes of Operation DIRECT MODE In Direct mode, the Volume Knob widget directly controls the volume of all of the DACs in the part. The volume in the Volume Knob widget acts as the master volume and limits the maximum volume for each of the DAC amplifiers. The amp gain for each of the DACs can also be adjusted using the DAC amplifiers. However, the actual gain for an individual DAC will be the sum of the Volume Knob volume and the DAC amplifier volume. For example, if the DAC amplifier gain is set to 0x7F (0dB) and the Volume Knob volume is set to 0x3F (-48dB) the resulting gain would be -48dB. If the combination of gains is less than -95.25dB (the equivalent to a value of 0x0 for the DAC or Volume Knob volume settings) then the actual gain will be -95.25dB. For example, if the Volume Knob is set to 0x3F (-48dB) and the DAC amplifier volume is set to 0x1F (-72dB) then the DAC volume will be set to -95.25dB. Direct mode is enabled by setting bit 7 in the Volume Knob Cntrl verb (F0F). The volume is reflected in the Volume Knob Cntrl bits 6:0 and the step size is 0.75dB. In direct mode, software can read or write the volume in the Volume Knob widget. * INDIRECT MODE In indirect mode, the Volume Knob widget does not directly control the DAC amplifier gains. An event on the volume Up/Down pins will increment/decrement the value in the Volume Knob Cntrl verb (F0F) volume bits (bits 6:0) just as in Direct mode. However, instead of adjusting the DAC amplifier gain, an unsolicited response is generated (if enabled) and the control software must read 30 EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT 92HDW74D V 1.0 03/08 92HDW74D EIGHT CHANNEL HD AUDIO CODEC, PREMIUM WLP 3/4 COMPLIANT PC AUDIO the volume in the Volume Knob widget and take appropriate action. Indirect mode is particularly useful when it is undesirable to control all of the DAC amplifier volumes at the same time, or when implementing ADC volume control. In indirect mode, there are only 128 volume levels in the Volume Knob Cntrl volume bits, the value will not go beyond the lower and upper limits (0x0 or 0x7F), and an unsolicited response will be generated if an input event tries to go beyond these limits. Therefore, it is the responsibility of the controlling software to monitor the volume in the Volume Knob Widget and take appropriate action. Indirect mode is enabled by clearing bit 7 in the Volume Knob Cntrl verb (F0F). The volume is reflected in the Volume Knob Cntrl bits 6:0 and the step size is 0.75dB. In direct mode, software can read or write the volume in the Volume Knob widget. 1.4.17.3. Hardware Implementation The Volume Knob interface is comprised of two input pins, CODEC pins 2 and 4. Both pins have internal pull-up resistors, so only two push button switches are required for most implementations. Typically, a series resistor and shunt capacitor are used to help reduce noise and prevent damage from ESD and other potential faults. An example circuit is shown below in below.

These registers are normally used by the CODEC driver to determine the configuration of jacks and devices attached to the CODEC. When the CODEC is powered on, these registers are loaded with the default values provided by IDT for typical system usage, and are loaded in a way that is compatible with the Microsoft Universal Audio Architecture (UAA) driver. The values can be overridden by IDT customers according to their system configuration. Table 18 shows the Pin Widget Configuration Default settings The settings reflect the Consumer Desktop use model with: *Independent Front Headphone and Microphone for real time communication *7.1 audio output at the rear *Rear Microphone and Line Input jacks *Optical SPDIF input and output jacks at the rear *HDMI *Digital Microphones are connected as a 4-mic array (Volume Knob Widget is visible, but inactive) *Analog CD input is connected to an internal ATAPI connector. .
