I
Single Rail / Dual Rail Select Input
This pin is used to select Single Rail or Dual Rail data formats. By default,
Dual Rail is selected. To select Single Rail mode, this pin must be pulled
"High". Once this pin is pulled "High", TNEGn/CODEn can be used to select
between AMI and HDB3 Encoding/Decoding.
NOTE: Internally pulled "Low" with a 50k
resistor.

I
Termination Impedance Select
TERSEL[1:0] are used to set the internal impedance of the LIU for the Receive
and Transmit paths.
"00" = 75
for Tx and "High-Z" for Rx
"01" = 120
for Tx and "High-Z" for Rx
"10" = 75
for Tx and Rx
"11" = 120
for Tx and Rx

I
Transmit Clock Data
"Low" = TPOS/TNEG data is sampled on the falling edge of TCLK
"High" = TPOS/TNEG data is sampled on the rising edge of TCLK
NOTE: Internally pulled "Low" with a 50k
resistor.
RCLKinv

I
Receive Clock Data
"Low" = RPOS/RNEG data is updated on the rising edge of RCLK
"High" = RPOS/RNEG data is updated on the falling edge of RCLK
NOTE: Internally pulled "Low" with a 50k
resistor.

I
Loop Back Mode Select
LBM[1:0] are used to configure the LIU into diagnostic loopback modes. To
select the channel number, see pins CHLB[3:0].
NOTE: Internally pulled "Low" with a 50k
resistor.

I
Jitter Attenuator Select
JASEL[1:0] are used to configure the jitter attenuator into the Receive or
Transmit path for all eight channels.
NOTE: Internally pulled "Low" with a 50k
resistor.
