8 / 64 page XRT73L04B 4 CHANNEL DS3/E3/STS-1 LINE INTERFACE UNIT REV. 1.0.1 4 PIN DESCRIPTIONS (BY FUNCTION) TRANSMIT INTERFACE PIN #NAME TYPE DESCRIPTION 34 25 3 12 TTIP_0 TTIP_1 TTIP_2 TTIP_3 O Transmit TTIP Output - Channel (n): The XRT73L04B uses this pin along with TRing_(n) to transmit a bipolar line signal via a 1:1 transformer. 32 23 5 14 TRing_0 TRing_1 TRing_2 TRing_3 O Transmit Ring Output - Channel (n): The XRT73L04B uses this pin along with TTIP_(n) to transmit a bipolar line signal via a 1:1 transformer. 42 30 139 7 TxClk_0 TxClk_1 TxClk_2 TxClk_3 I Transmit Clock Input for TPData and TNData - Channel (n): This input pin must be driven at 34.368 MHz (for E3 applications), 44.736 MHz (for DS3 applications), or 51.84 MHz (for SONET STS-1 applications). The XRT73L04B uses this signal to sample the TPData_(n) and TNData_(n) input pins. By default, the XRT73L04B is configured to sample these two pins on the falling edge of this signal. NOTE: If the XRT73L04B is operating in the HOST Mode, then the device can be configured to sample the TPData_(n) and TNData_(n) input pins on either the rising or falling edge of TxClk_(n). 41 29 140 8 TPData_0 TPData_1 TPData_2 TPData_3 I Transmit Positive Data Input - Channel (n): The XRT73L04B samples this pin on the falling edge of TxClk_(n). If the device samples a "1", then it generates and transmits a positive polarity pulse to the line. The data should be applied to this input pin if the Transmit Section is configured to accept Single-Rail data from the Terminal Equipment. NOTE: If the XRT73L04B is operating in the HOST Mode, then the XRT73L04B can be configured to sample the TPData_(n) pin on either the rising or falling edge of TxClk_(n). 40 28 141 9 TNData_0 TNData_1 TNData_2 TNData_3 I Transmit Negative Data Input - Channel (n): The XRT73L04B samples this pin on the falling edge of TxClk_(n). If the device samples a "1", then it generates and transmits a negative polarity pulse to the line. In Single-Rail Mode, this pin must be tied to GND to enable the HDB3/ B3ZS Encoder and Decoder, (internally pulled-down). In Dual-Rail Mode this input is the N-Rail Data input. NOTE: If the XRT73L04B is operating in the HOST Mode, then the XRT73L04B can be configured to sample the TNData_(n) pin on either the rising or falling edge of TxClk_(n). |
