2.0 Circuit Description
Quad/x16/Octal—T1/E1/J1 Framers
2.4 Transmitter
The output on TPOSO/TNEGO can be changed from dual rail bipolar to NRZ
unipolar data (TNRZO) and to multiframe sync clock (MSYNCO), using the
Transmit NRZ Data (TNRZ) bit in TCR1[addr 071]. Figures 2-25 and 2-26
illustrate transmit signal timing for both bipolar and unipolar operation.
