Wide Jitter Attenuation bandwidth
= 0: normal mode
= 1: JA limit mode
Jitter Attenuator configuration
= 00/10: JA not used
= 01: JA in transmit path
= 11: JA in receive path
Jitter Attenuator depth selection
= 00: 128 bits
= 01: 64 bits
= 10/11: 32 bits
Jitter transfer function bandwidth selection
Reserved
Transmitter power down enable
= 0: Transmitter power up
= 1: Transmitter power down and line driver high impedance
= 0: data on TDn or TDPn/TDNn is active high
= 1: data on TDn or TDPn/TDNn is active low
= 0: data on TDn or TDPn/TDNn is sampled on the falling edges of TCLKn
= 1: data on TDn or TDPn/TDNn is sampled on the rising edges of TCLKn
Transmitter operation mode control bits which select different stages of transmit data path
= 00: enable HDB3/B8ZS encoder and waveform shaper blocks, input on 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
