Transmitter power down enable
= 0: Transmitter power up
= 1: Transmitter power down (line driver high impedance)
Transmit data invert
= 0: Data on TDn or TDPn/TDNn is active high
= 1: Data on TDn or TDPn/TDNn is active low
Transmit clock edge select
= 0: Data on TDPn/TDNn is sampled on the falling edge of TCLKn
= 1: Data on TDPn/TDNn is sampled on the rising edge of TCLKn
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 TDn is single rail NRZ data
= 01: Enable AMI encoder and waveform shaper blocks. Input on pin TDn is single rail NRZ data
= 1x: Encoder is bypassed, dual rail NRZ transmit data input on pin TDPn/TDNn
