XRT86VL38 OCTAL T1/E1/J1 FRAMER/LIU COMBO - HARDWARE DESCRIPTION JANUARY 2007 REV. V1.2.0 GENERAL DESCRIPTION The XRT86VL38 is an eight-channel 1.544 Mbit/s or 2.048 Mbit/s DS1/E1/J1 framer and LIU integrated solution featuring R3 technology (Relayless, Reconfigurable, Redundancy). The physical interface is optimized with internal impedance, and with the patented pad structure, the XRT86VL38 provides protection from power failures and hot swapping. The XRT86VL38 contains an integrated DS1/E1/J1 framer and LIU which provide DS1/E1/J1 framing and error accumulation in accordance with ANSI/ITU_T specifications. Each framer has its own framing synchronizer and transmit-receive slip buffers. The slip buffers can be independently enabled or disabled as required and can be configured to frame to the common DS1/E1/J1 signal formats. Each Framer block contains its own Transmit and Receive T1/E1/J1 Framing function. There are 3 Transmit HDLC controllers per channel which encapsulate contents of the Transmit HDLC buffers into LAPD Message frames. There are 3 Receive HDLC controllers per channel which extract the payload content of Receive LAPD Message frames from the incoming T1/E1/J1 data stream and write the contents into the Receive HDLC buffers. Each framer also contains a Transmit and Overhead Data Input port, which permits Data Link Terminal Equipment direct access to the outbound T1/E1/J1 frames. Likewise, a Receive Overhead output data port permits Data Link Terminal Equipment direct access to the Data Link bits of the inbound T1/E1/J1 frames. The XRT86VL38 fully meets all of the latest T1/E1/J1 specifications: ANSI T1/E1.107-1988, ANSI T1/ E1.403-1995, ANSI T1/E1.231-1993, ANSI T1/ E1.408-1990, AT&T TR 62411 (12-90) TR54016, and ITU G-703, G.704, G706 and G.733, AT&T Pub. 43801, and ETS 300 011, 300 233, JT G.703, JT G.704, JT G706, I.431. Extensive test and diagnostic functions include Loop-backs, Boundary scan, Pseudo Random bit sequence (PRBS) test pattern generation, Performance Monitor, Bit Error Rate (BER) meter, forced error insertion, and LAPD unchannelized data payload processing according to ITU-T standard Q.921.

DS1/E1 Mode - TxSERn These pins function as the transmit serial data input on the system side interface, which are latched on the rising edge of the TxSERCLKn pin. Any payload data applied to this pin will be inserted into an outbound DS1/E1 frame and output to the line. In DS1 mode, the framing alignment bits, facility data link bits, CRC-6 bits, and signaling information can also be inserted from this input pin if configured appropriately. In E1 mode, all data intended to be transported via Time Slots 1 through 15 and Time slots 17 through 31 must be applied to this input pin. Data intended for Time Slots 0 and 16 can also be applied to this input pin If configured accordingly. DS1 or E1 High-Speed Multiplexed Mode* - TxSERn In this mode, these pins are used as the high-speed multiplexed data input pin on the system side. High-speed multiplexed data of channels 0-3 must be applied to TxSER0 and high-speed multiplexed data of channels 4-7 must be applied to TxSER4 in a byte or bit-interleaved way. The framer latches in the multiplexed data on TxSER0 and TxSER4 using TxMSYNC/TxINCLK and demultiplexes this data into 4 serial streams. The LIU block will then output the data to the line interface using TxSERCLKn. DS1 or E1 Framer Bypass Mode - TxPOSn In this mode, TxSERn is used for the positive digital input pin (TxPOSn) to the LIU. NOTE: 15 1. *High-speed multiplexed modes include (For T1/E1) 16.384MHz HMVIP, H.100, Bit-multiplexed modes, and (For T1 only) 12.352MHz Bit-multiplexed mode. 2. In DS1 high-speed modes, the DS-0 data is mapped into an E1 frame by ignoring every fourth time slot (don't care). 3. These 8 pins are internally pulled "High" for each channel.

In Base-Rate Mode (1.544MHz/2.048MHz) - TxSERCLKn: This clock signal is used by the transmit serial interface to latch the contents on the TxSERn pins into the T1/E1 framer on the rising edge of the TxSERCLKn. These pins can be configured as input or output as described below. When TxSERCLKn is configured as Input: These pins will be inputs if the TxSERCLK is chosen as the timing source for the transmit framer. Users must provide a 1.544MHz clock rate to this input pin for T1 mode of operation, and 2.048MHz clock rate in E1 mode. When TxSERCLKn is configured as Output: These pins will be outputs if either the recovered line clock or the MCLK PLL is chosen as the timing source for the T1/E1 transmit framer. The transmit framer will output a 1.544MHz clock rate in T1 mode of operation, and a 2.048MHz clock rate in E1 mode. DS1/E1 High-Speed Backplane Modes* - TxSERCLKn as INPUT ONLY In this mode, TxSERCLK is an optional clock signal input which is used as the timing source for the transmit line interface, and is only required if TxSERCLK is chosen as the timing source for the transmit framer. If TxSERCLK is chosen as the timing source, system equipment should provide 1.544MHz (For T1 mode) or 2.048MHz (For E1 mode) to the TxSERCLKn pins on each channel. TxSERCLK is not required if either the recovered clock or MCLK PLL is chosen as the timing source of the device. High speed or multiplexed data is latched into the device using the TxMSYNC/TxINCLK high-speed clock signal. DS1 or E1 Framer Bypass Mode - TxLINECLKn In this mode, TxSERCLKn is used as the transmit line clock (TxLINECLK) to the LIU. NOTE: *High-speed backplane modes include (For T1/E1) 2.048MVIP, 4.096MHz, 8.192MHz, 16.384MHz HMVIP, H.100, Bit-multiplexed modes, and (For T1 only) 12.352MHz Bit-multiplexed mode.

DS1/E1 Base Rate Mode (1.544MHz/2.048MHz) - TxSYNCn: These TxSYNCn pins are used to indicate the single frame boundary within an outbound T1/E1 frame. In both DS1 or E1 mode, the single frame boundary repeats every 125 microseconds (8kHz). In DS1/E1 base rate, TxSYNCn can be configured as either input or output as described below. When TxSYNCn is configured as an Input: Users must provide a signal which must pulse "High" for one period of TxSERCLK during the first bit of an outbound DS1/ E1 frame. It is imperative that the TxSYNC input signal be synchronized with the TxSERCLK input signal. When TxSYNCn is configured as an Output: The transmit T1/E1 framer will output a signal which pulses "High" for one period of TxSERCLK during the first bit of an outbound DS1/E1 frame. DS1/E1 High-Speed Backplane Modes* - TxSYNCn as INPUT ONLY: In this mode, TxSYNCn must be an input regardless of the clock source that is chosen to be the timing source for the transmit framer. In 2.048MVIP/4.096/8.192MHz high-speed modes, TxSYNCn pins must be pulsed 'High' for one period of TxSERCLK during the first bit of the outbound T1/E1 frame. In HMVIP mode, TxSYNC0 and TxSYNC4 must be pulsed 'High' for 4 clock cycles of the TxMSYNC/TxINCLK signal in the position of the first two and the last two bits of a multiplexed frame. In H.100 mode, TxSYNC0 and TxSYNC4 must be pulsed 'High' for 2 clock cycles of the TxMSYNC/TxINCLK signal in the position of the first and the last bit of a multiplexed frame. DS1 or E1 Framer Bypass Mode - TxNEGn In this mode, TxSYNCn is used as the negative digital input pin (TxNEG) to the LIU. NOTE: *High-speed backplane modes include (For T1/E1) 2.048MVIP, 4.096MHz, 8.192MHz, 16.384MHz HMVIP, H.100, Bit-multiplexed modes, and (For T1 only) 12.352MHz Bit-multiplexed mode. NOTE: In DS1 high-speed modes, the DS-0 data is mapped into an E1 frame by ignoring every fourth time slot (don't care). NOTE: 17 These 8 pins are internally pulled "Low" for each channel.

DS1/E1 Base Rate Mode (1.544MHz/2.048MHz) - TxMSYNCn In this mode, these pins are used to indicate the multi-frame boundary within an outbound DS1/E1 frame. In DS1 ESF mode, TxMSYNCn repeats every 3ms. In DS1 SF mode, TxMSYNCn repeats every 1.5ms. In E1 mode, TxMSYNCn repeats every 2ms. If TxMSYNCn is configured as an input, TxMSYNCn must pulse "High" for one period of TxSERCLK during the first bit of an outbound DS1/E1 multi-frame. It is imperative that the TxMSYNC input signal be synchronized with the TxSERCLK input signal. If TxMSYNCn is configured as an output, the transmit section of the T1/E1 framer will output and pulse TxMSYNC "High" for one period of TxSERCLK during the first bit of an outbound DS1/E1 frame. DS1/E1 High-Speed Backplane Modes* - (TxINCLKn as INPUT ONLY) In this mode, this pin must be used as the high-speed input clock pin (TxINCLKn) for the backplane interface to latch in high-speed or multiplexed data on the TxSERn pin. The frequency of TxINCLK is presented in the table below.

If transmit fractional/signaling interface is disabled: This pin indicates the boundary of each time slot of an outbound DS1/E1 frame. In T1 mode, each of these output pins is a 192kHz clock which pulses "High" during the LSB of each 24 time slots. In E1 mode, each of these output pins is a 256kHz clock which pulses "High" during the LSB of each 32 time slots. The Terminal Equipment can use this clock signal to sample the TxCHN0 through TxCHN4 time slot identifier pins to determine which time slot is being processed. If transmit fractional/signaling interface is enabled: TxCHCLKn is the fractional interface clock which either outputs a clock signal for the time slot that has been configured to input fractional data, or outputs an enable signal for the fractional time slot so that fractional data can be clocked into the device using the TxSERCLK pin. NOTE: 19 Transmit fractional interface can be enabled by programming to bit 4 - TxFr1544/TxFr2048 bit from register 0xn120 to `1'.

Terminal Equipment can use the TxCHCLK to sample the five output pins of each channel in order to identify the time slot being processed. This pin indicates the Least Significant Bit (LSB) of the time slot channel being processed. If transmit fractional/signaling interface is enabled TxSIGn: These pins can be used to input robbed-bit signaling data to be inserted within an outbound DS1 frame or to input Channel Associated Signaling (CAS) data within an outbound E1 frame, as described below. T1 Mode: Signaling data (A,B,C,D) of each channel must be provided on bit 4,5,6,7 of each time slot on the TxSIG pin if 16code signaling is used. If 4-code signaling is selected, signaling data (A,B) of each channel must be provided on bit 4, 5 of each time slot on the TxSIG pin. If 2-code signaling is selected, signaling data (A) of each channel must be provided on bit 4 of each time slot on the TxSIG pin. E1 Mode: Signaling data in E1 mode can be provided on the TxSIGn pins on a time-slot-basis as in T1 mode, or it can be provided on time slot 16 only via the TxSIGn input pins. In the latter case, signaling data (A,B,C,D) of channel 1 and channel 17 must be inserted on the TxSIGn pin during time slot 16 of frame 1, signaling data (A,B,C,D) of channel 2 and channel 18 must be inserted on the TxSIGn pin during time slot 16 of frame 2...etc. The CAS multiframe Alignments bits (0000 bits) and the extra bits/alarm bit (xyxx) must be inserted on the TxSIGn pin during time slot 16 of frame 0.

When RxSYNCn is configured as an Input: Users must provide a signal which must pulse "High" for one period of RxSERCLK and repeats every 125S. The receive serial Interface will output the first bit of an inbound DS1/E1 frame during the provided RxSYNC pulse. NOTE: It is imperative that the RxSYNC input signal be synchronized with the RxSERCLK input signal. When RxSYNCn is configured as an Output: The receive T1/E1 framer will output a signal which pulses "High" for one period of RxSERCLK during the first bit of an inbound DS1/E1 frame.

When DMA interface is enabled, these 8-bit bidirectional data bus is also used by the T1/E1 Framer or the external DMA Controller for storing and retrieving information. U19 O 8 DMA Cycle Request Output--DMA Controller 0 (Write): These output pins are used to indicate that DMA transfers (Write) are requested by the T1/E1 Framer. On the transmit side (i.e., To transmit data from external DMA controller to HDLC buffers within the XRT86VL38), DMA transfers are only requested when the transmit buffer status bits indicate that there is space for a complete message or cell. The DMA Write cycle starts by T1/E1 Framer asserting the DMA Request (REQ0) `low', then the external DMA controller should drive the DMA Acknowledge (ACK0) `low' to indicate that it is ready to start the transfer. The external DMA controller should place new data on the Microprocessor data bus each time the Write Signal is Strobed low if the WR is configured as a Write Strobe. If WR is configured as a direction signal, then the external DMA controller would place new data on the Microprocessor data bus each time the Read Signal (RD) is Strobed low. The Framer asserts this output pin (toggles it "Low") when at least one of the Transmit HDLC buffers are empty and can receive one more HDLC message. The Framer negates this output pin (toggles it "High") when the HDLC buffer can no longer receive another HDLC message.

On the receive side (i.e., To transmit data from HDLC buffers within the XRT86VL38 to external DMA Controller), DMA transfers are only requested when the receive buffer contains a complete message or cell. The DMA Read cycle starts by T1/E1 Framer asserting the DMA Request (REQ1) `low', then the external DMA controller should drive the DMA Acknowledge (ACK1) `low' to indicate that it is ready to receive the data. The T1/E1 Framer should place new data on the Microprocessor data bus each time the Read Signal is Strobed low if the RD is configured as a Read Strobe. If RD is configured as a direction signal, then the T1/E1 Framer would place new data on the Microprocessor data bus each time the Write Signal (WR) is Strobed low. The Framer asserts this output pin (toggles it "Low") when one of the Receive HDLC buffer contains a complete HDLC message that needs to be read by the C/P. The Framer negates this output pin (toggles it "High") when the Receive HDLC buffers are depleted.

In the Motorola Mode, a "READ" operation occurs if this pin is held at a logic "1", coincident to a falling edge of the RD/DS (Data Strobe) input pin. Similarly a WRITE operation occurs if this pin is at a logic "0", coincident to a falling edge of the RD/DS (Data Strobe) input pin. DESCRIPTION 46 XRT86VL38 OCTAL T1/E1/J1 FRAMER/LIU COMBO - HARDWARE DESCRIPTION REV. V1.2.0 MICROPROCESSOR INTERFACE SIGNAL NAME 420 PKG BALL# 484PKG BALL # TYPE OUTPUT DRIVE (MA) WR M23 L20 I - DESCRIPTION (Con't) Power PC 403 Mode - R/W - Read/Write Operation Identification Input: This input pin will function as the "Read/Write Operation Identification Input" pin. Anytime the Microprocessor Interface samples this input signal at a logic "High" (while also sampling the CS input pin "Low") upon the rising edge of PCLK, then the Microprocessor Interface will (upon the very same rising edge of PCLK) latch the contents of the Address Bus (A[14:0]) into the Microprocessor Interface circuitry, in preparation for this forthcoming READ operation. At some point (later in this READ operation) the Microprocessor will also assert the DBEN/OE input pin, and the Microprocessor Interface will then place the contents of the "target" register (or address location within the XRT86VL38 device) upon the Bi-Directional Data Bus pins (D[7:0]), where it can be read by the Microprocessor. Anytime the Microprocessor Interface samples this input signal at a logic "Low" (while also sampling the CS input pin a logic "Low") upon the rising edge of PCLK, then the Microprocessor Interface will (upon the very same rising edge of PCLK) latch the contents of the Address Bus (A[14:0]) into the Microprocessor Interface circuitry, in preparation for the forthcoming WRITE operation. At some point (later in this WRITE operation) the Microprocessor will also assert the RD/DS/WE input pin, and the Microprocessor Interface will then latch the contents of the Bi-Directional Data Bus (D[7:0]) into the contents of the "target" register or buffer location (within the XRT86VL38). 47 XRT86VL38 OCTAL T1/E1/J1 FRAMER/LIU COMBO - HARDWARE DESCRIPTION REV. V1.2.0 MICROPROCESSOR INTERFACE SIGNAL NAME 420 PKG BALL# 484PKG BALL # TYPE OUTPUT DRIVE (MA) ACK0 Y23 W22 I - DESCRIPTION DMA Cycle Acknowledge Input--DMA Controller 0 (Write): The external DMA Controller will assert this input pin "Low" when the following two conditions are met: 1. After the DMA Controller, within the Framer has asserted (toggled "Low"), the Req_0 output signal. 2. When the external DMA Controller is ready to transfer data from external memory to the selected Transmit HDLC buffer. ACK1 Y24 V21 At this point, the DMA transfer between the external memory and the selected Transmit HDLC buffer may begin. After completion of the DMA cycle, the external DMA Controller will negate this input pin after the DMA Controller within the Framer has negated the Req_0 output pin. The external DMA Controller must do this in order to acknowledge the end of the DMA cycle. DMA Cycle Acknowledge Input--DMA Controller 1 (Read): The external DMA Controller asserts this input pin "Low" when the following two conditions are met: 1. After the DMA Controller, within the Framer has asserted (toggled "Low"), the Req_1 output signal. 2. When the external DMA Controller is ready to transfer data from the selected Receive HDLC buffer to external memory. At this point, the DMA transfer between the selected Receive HDLC buffer and the external memory may begin. After completion of the DMA cycle, the external DMA Controller will negate this input pin after the DMA Controller within the Framer has negated the Req_1 output pin. The external DMA Controller will do this in order to acknowledge the end of the DMA cycle. NOTE: 48 This pin is internally pulled "High" with a 50k resistor. XRT86VL38 OCTAL T1/E1/J1 FRAMER/LIU COMBO - HARDWARE DESCRIPTION REV. V1.2.0 MICROPROCESSOR INTERFACE SIGNAL NAME 420 PKG BALL# 484PKG BALL # TYPE OUTPUT DRIVE (MA) BLAST P23 M17 I - DESCRIPTION Last Cycle of Burst Indicator Input: If the Microprocessor Interface is operating in the Intel-I960 Mode, then this input pin is used to indicate (to the Microprocessor Interface block) that the current data transfer is the last data transfer within the current burst operation. The Microprocessor should assert this input pin (by toggling it "Low") in order to denote that the current READ or WRITE operation (within a BURST operation) is the last operation of this BURST operation. NOTES: RESET Y4 Y1 I - 1. If the user has configured the Microprocessor Interface to operate in the Intel-Asynchronous, the Motorola-Asynchronous or the Power PC 403 Mode, then he/she should tie this input pin to GND. 2. This pin is internally pulled "High" with a 50k resistor. Hardware Reset Input Reset is an active low input. If this pin is pulled "Low" for more than 10S, the device will be reset. When this occurs, all output will be `tri-stated', and all internal registers will be reset to their default values.
