TRANSMIT PATH CONTROL REGISTERS
1. In internal impedance matching mode, for E1/75
cable impedance, the PULS[3:0] bits (TCF1, 06H) should be set to ‘0000’. In external impedance matching mode, for E1/75 cable
impedance, the PULS[3:0] bits should be set to ‘0001’.

0
Transmitter power down enable
= 0: Transmitter power up
= 1: Transmitter power down (line driver high impedance)
TD_INV

0
Transmit data invert
= 0: Data on TD or TDP/TDN is active high
= 1: Data on TD or TDP/TDN is active low
TCLK_SEL
2
0
Transmit clock edge select
= 0: Data on TDP/TDN is sampled on the falling edge of TCLK
= 1: Data on TDP/TDN is sampled on the rising edge of TCLK
T_MD[1:0]
0-1
00
Transmitter operation mode control
T_MD[1:0] select different stages of the transmit data path
= 00: Enable HDB3/B8ZS encoder and waveform shaper blocks. Input on pin TD is single rail NRZ data
= 01: Enable AMI encoder and waveform shaper blocks. Input on pin TD is single rail NRZ data
= 1x: Encoder is bypassed, dual rail NRZ transmit data input on pin TDP/TDN
