an ACL logical transport, it shall listen in every ACL slot to the master traffic, unless that link is being treated as a scatternet link or
is absent due to hold mode. With sniff mode, the time slots when a slave is listening are reduced, so the master shall only transmit to
a slave in specified time slots. The sniff anchor points are spaced regularly with an interval of Tsniff.

The module may be reset from several sources: RESETB pin, power-on reset, a UART break character or via software
configured watchdog timer.
The RESETB pin is an active low reset and is internally filtered using the internal low frequency clock oscillator. A reset will
be performed between 1.5 and 4.0ms following RESETB being active. It is recommended that RESETB be applied for a
period greater than 5ms.
At reset the digital I/O pins are set to inputs for bi-directional pins and outputs are tri-state. The pull-down state is shown
below.
Note: Pull-up (PU) and pull-down (PD) default to weak values unless specified otherwise.
Digital Audio Interfaces

PCM
The audio pulse code modulation (PCM) interface supports continuous transmission and reception of PCM encoded
audio data over Bluetooth.
Hardware on ABBTM-NVC-MDCS56 allows the data to be sent to and received from a SCO connection. Up to three
SCO connections can be supported by the PCM interface at any one time.
ABBTM-NVC-MDCS56 can operate as the PCM interface master generating PCM_SYNC and PCM_CLK or as a PCM
interface slave accepting externally generated PCM_SYNC and PCM_CLK.
ABBTM-NVC-MDCS56 is compatible with a variety of clock formats, including Long Frame Sync, Short Frame Sync
and GCI timing environments.
It supports 13-bit or 16-bit linear, 8-bit u-law or A-law companded sample formats and can receive and transmit on any
selection of three of the first four slots following PCM_SYNC.
ABBTM-NVC-MDCS56 interfaces directly to PCM audio devices including the following:
• Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices
• OKI MSM7705 four channel A-law and μ-law CODEC

IEC 60958 Interface (SPDIF)
Figure 7. Example Circuit for SPDIF Interface (Optical)
Figure 6. Example Circuit for SPDIF Interface (Co-Axial)
The IEC 60958 interface is a digital audio interface that uses bi-phase coding to minimize the DC content of the transmit-
ted signal and allows the receiver to decode the clock information from the transmitted signal. The IEC 60958 specifica-
tion is based on the 2 industry standards:
• AES/EBU
• Sony and Philips interface specification SPDIF
The interface is compatible with IEC 60958-1, IEC 60958-3 and IEC 60958-4.
The SPDIF interface signals are SPDIF_IN and SPDIF_OUT and are shared on the PCM interface pins. The input and
output stages of the SPDIF pins can interface to:
• A 75Ω coaxial cable with an RCA connector, see Figure 6.
• An optical link that uses Toslink optical components, see Figure 7.

Microphone Input
The audio input is intended for use in the range from 1μA @ 94dB SPL to about 10μA @ 94dB SPL. With biasing
resistors R1 and R2 equal to 1kΩ, this requires microphones with sensitivity between about –40dBV and –60dBV. The
microphone for each channel should be biased as shown in Figure 8.
Figure 8. Microphone Biasing (Single Channel Shown)
Analog Output Stage
The output stage digital circuitry converts the signal from 16-bit per sample, linear PCM of variable sampling frequency
to a 2Mbits/s 5-bit multi-bit bit stream, which is fed into the analogue output circuitry.
The output stage circuit is comprised a DAC with gain setting and class AB amplifier. The output is available as a
differential signal between SPKR_A_N and SPKR_L_P for the right channel, as Figure 9 shows, and between
SPKL_B_N and SPKL_B_P for the left channel.
RF Interface
Input impedance of the RF port is 50Ω so the user can connect a 50Ω antenna directly to the RF port.
General Purpose Analog IO
The module has two general-purpose analogue interface pins, AIO0 and AIO1. These are used to access internal circuitry
and control signals. Auxiliary functions available via these pins include a 10-bit ADC. Signals selectable at these pins
include the band gap reference voltage and a variety of clock signals: 64, 48, 32, 24, 16, 12, 8, 6 and 2MHz (outputted
from AIO0 only) and the XTAL and XTAL/2 clock frequency (outputted from AIO0 and AIO1).
Please do not connect them if not use.
General Purpose Digital IO
The module has several general-purpose bi-directional input/outputs (I/O). Any of the PIO lines can be configured as
interrupt request lines or wake-up lines from sleep modes.
There are nine general purpose digital IOs defined in the module. All these GPIOs can be configured by software to
realize various functions, such as button controls, LED displays or interrupt signals to host controller, etc. Please do not
connect them if not use.

Bluetooth UART
The module has a standard UART serial interface that provides a simple mechanism for communicating using RS232
protocol. When the module is connected to another digital device, UART_RX and UART_TX transfer data between the
2 devices.
Table 4. Possible UART Settings
USB
This is a full speed (12M bits/s) USB interface for communicating with other compatible digital devices. The module
acts as a USB peripheral, responding to request from a master host controller, such as a PC.
The USB interface is capable of driving a USB cable directly. No external USB transceiver is required. The device
operates as a USB peripheral, responding to requests from a master host controller such as a PC. Both the OHCI and the
UHCI standards are supported. The set of USB endpoints implemented can behave as specified in the USB section of the
Bluetooth specification v2.0+EDR or alternatively can appear as a set of endpoints appropriate to USB audio devices
such as speakers.
The module has an internal USB pull-up resistor. This pulls the USB_DP pin weakly high when module is ready to
enumerate. It signals to the USB master that it is a full speed (12Mbit/s) USB device.
I2C
PIO8, PIO7 and PIO6 can be used to form a master I2C interface as shown in Figure 10. PIO lines need to be pulled up
through 2.2Kohm resistors.

ABBTM-NVC-MDCS56 requires an external antenna to radiate and receive the RF signals. Please follow general RF
design guidelines to ensure a good RF performance.
Placement of the Module and Antenna
If PCB antenna is used, please take precaution with the antenna placement. Figure 13 shows some examples of the
antenna placement.

RF LAYOUT GUIDELINE
Feed Line and Antenna
The impedance of the feed line between the RF port and the antenna shall be 50Ω.
• A good ground directly under the feed line is always needed for impedance control.
• Route the feed line as curve lines when needed, avoid 90 or even less degree angles style.
• The width of the feed line, the distance of the feed line to the ground plane are keys to the impedance.
Please ask your PCB supplier to control the impedance of the feed line.
For the antenna,
• When PCB antenna is used, matching networks shall be used to optimize the antenna’s signal strength.
• Use as many vias as possible to connect the ground planes nearby the antenna.

Key features of the profile:
• Initial Ramp = 1-2.5°C/sec to 175°C ±25°C equilibrium
• Equilibrium time = 60 to 180 seconds
• Ramp to Maximum temperature (250°C) = 3°C/sec max.
• Time above liquidus temperature (217°C): 45-90 seconds
• Device absolute maximum reflow temperature: 255°C
REFLOW PROFILE:
ABBTM-NVC-MDCS56 is compatible with industrial standard reflow profile for Pb-free solders. The soldering profile
depends on various parameters necessitating a set up for each application. The data here is given only for guidance on solder
re-flow. There are four zones:
1. Preheat Zone - This zone raises the temperature at a controlled rate, typically 1-2.5°C/s.
2. Equilibrium Zone - This zone brings the board to a uniform temperature and also activates the flux. The duration in this
zone (typically 2-3 minutes) will need to be adjusted to optimise the out gassing of the flux.
3. Reflow Zone- The peak temperature should be high enough to achieve good wetting but not so high as to cause compo-
nent discoloration or damage. Excessive soldering time can lead to intermetallic growth which can result in a brittle joint.
4. Cooling Zone - The cooling rate should be fast, to keep the solder grains small which will give a longer lasting joint. Typical
rates will be 2-5°C/s.
