DS21348 pin
(WR_NRZ)
Pin bias for DS21348. When not jumpered, this pin
is pulled to ground, jumper drives pin to VCC. A
basic description of the pin function is given below.
Refer to the data sheet for full details.
0 = -12dB (short haul)
1 = -43dB (long haul)
0 = E1
1 = T1
0 = Bipolar data at RPOS/RNEG and TPOS/TNEG
1 = NRZ data at RPOS and TPOS or TNEG; RNEG
outputs a positive-going pulse when device
receives a BPV, CV, or EXZ
0 = disable 2.048MHz synchronization transmit and
