Clock and Data Recover Unit Reference Frequency Select
Selects the Clock and Data Recovery Unit reference frequency
based on the table below.
"Low" = CDR uses CMU’s reference clock
"High" = CDR reference clock from CDRAUXREFCLK
NOTE:
CDRAUXREFCLK requires accuracy of 77.76 MHz
+/- 500ppm.

Loop Timing Mode
When the loop timing mode is activated the external reference
clock to the input of the Retimer is replaced with the high-speed
recovered receive clock from the CDR.
"Low" = Disabled
"High" = Loop timing Activated

Clock and Data Recovery Unit Disable
Active "High." Disables internal Clock and Data Recovery unit.
Received serial data bypasses the integrated CDR block.
RXINP/N is then sampled on the rising edge of externally
recovered differential clock XRXCLKIP/N coming from the opti-
cal module.
"Low" = Internal CDR unit is Enabled
"High" = Internal CDR unit is Disabled and Bypassed

Transmit Parallel Clock Directional Control
Transmit Parallel Clock Output Operation
If this pin is asserted "High", TXPCLK_IO is a parallel bus clock
output. Data on the TXDI[7:0] must be synchronously applied
prior to the sampling by the PISO at the rising edge of
TXPCLK_IO clock output driven by the XRT91L30.
Alternate Transmit Parallel Clock Input Operation
Asserting this control pin "Low" or if left unconnected, it config-
ures TXPCLK_IO to serve as a parallel bus clock input rather
than a parallel bus clock output and permits the XRT91L30 to
accept the external clock input. Data on the TXDI[7:0] is then
sampled at the rising edge of the TXPCLK_IO clock input
driven by the framer/mapper device.
"Low" = TXPCLK_IO is a Parallel Clock Input.
"High" = TXPCLK_IO is a Parallel Clock Output.
NOTE:
Parallel Clock Input operation has the advantage of
permitting the framer/mapper device timing to be
synchronized with the transceiver transmitter timing.
This pin is provided with an internal pull-down.
