5 / 37 page  XRT5997 5 Rev. 1.0.0 Pin# Symbol Type Description 14 AGND - Analog Ground - Receiver 1, 2, 3, 5. 15 TTIP2 O Transmitter 2 Positive Bipolar Output: Channel 2 within the XRT5997 device will use this pin, along with TRing2, to transmit a bipolar line signal, via a 1:2 step-up transformer. 16 TVDD2 - Positive Supply - (+3.3V ± 5%), Transmitters 2. 17 TRing2 O Transmitter 2 Negative Bipolar Output: Channel 2 within the XRT5997 device will use this pin, along with TTIP2, to transmit a bipolar line signal, via a 1:2 step-up transformer. 18 TGND2 Digital Ground - Transmitters 2. 19 TRing3 O Transmitter 3 Negative Bipolar Output: Channel 3 within the XRT5997 device will use this pin, along with TTIP3, to transmit a bipolar line signal, via a 1:2 step-up transformer. 20 TVDD3 Positive Supply - (+3.3V ± 5%), Transmitters 3. 21 TTIP3 O Transmitter 3 Positive Bipolar Output: Channel 3 within the XRT5997 device will use this pin, along with TRing3, to transmit a bipolar line signal, via a 1:2 step-up transformer. 22 TGND3 Digital Ground - Transmitters 3. 23 RTIP3 I Receiver 3 Positive Bipolar Input. The Receive Section of Channel 4 uses this input pin, along with RRing3 to receive the bipolar line signal from the “Remote E1 Terminal”. 24 RRing3 I Receiver 3 Negative Bipolar Input. The Receive Section of Channel 3 uses this input pin, along with RTIP3 to receive the bipolar line signal from the “Remote E1 Terminal”. 25 TxClk3 I Transmitter Clock Input – Channel 3: If the user operates Channel 3 (within the XRT5997 device) in the “clocked” mode, then the “Transmit Section” of the Channel 3 will use the falling edge of this signal to sample the data at the TxPOS3 and TxNEG3 input pins. Note: If the user operates the Channel 3 in the “clockless” mode, then the Terminal Equipment should not apply a clock signal to this input pin. PIN DESCRIPTION (CONT'D) |
