RClkP
I-L
Receiver Clock Output Polarity: (Hardware Mode)
"Low", All channel RPOS /RDATA and RNEG/LCV output data are
updated on the falling edge of RClk.
"High" to select data update on rising edge of RClk.
66
TClkP
I-L
Transmit Clock Polarity: (Hardware Mode)
"Low", transmit input data is sampled using the falling edge of TClk.
"High" to select rising edge of TClk for data sampling.

MClk
I
Master Clock Input:
This signal is an independent 2.048MHz clock with accuracy better than
±50ppm and duty cycle within 40% to 60%. The function of MCLK is to
provide timing source for the PLL clock recovery circuit, reference clock
to insert All Ones data in the transmit as well as the receive paths.
