CDR’s Recovered High-speed Serial Clock Reference
Controls CDR’s operation.
"Low" = Forced to lock to CDR PLL reference training clock
"High" = Normal Operation (Locked to incoming serial data)
This pin is provided with an internal pull-up.

Receive Parallel Data Output Disable
Hardware Mode
If this pin is set to "0", the 16-bit parallel
receive data output will asynchronously mute.
"Low" = Forces RXDO[15:0]P/N to a logic state of "0"
"High" = Normal Mode
This pin is provided with an internal pull-up.
Host Mode 2

-1 PRBS Pattern Lock Output Indicator
This pin indicates the current state condition of the PRBS pat-
tern analyzer when the PRBS pattern generator is enabled.
"Low" = PRBS pattern analyzer currently Out of Lock
"High" = PRBS pattern analyzer currently Locked

Receive Parallel Clock Output Disable
This pin is used to asynchronously control the activity of the
parallel receive clock output.
"Low" = Forces RXPCLKOP/N to a logic state of "0"
"High" = Normal Mode
This pin is provided with an internal pull-up.

CDR Lock Detect
This pin is used to monitor the lock condition of the clock and
data recovery unit.
"Low" = CDR Out of Lock
"High" = CDR Locked

Signal Detect Input from Optical Module
When inactive, it will automatically mute received data output
bus RXDO[15:0]P/N upon Loss of Signal Detection (LOSD)
condition.
"Active" = Normal Operation (SDEXT detects signal presence)
"Inactive" =Mutes upon LOSD (SDEXT detects signal absence)
This pin is provided with an internal pull-up.
POLARITY

E10
Polarity for SDEXT Input
Controls the Signal Detect polarity convention of SDEXT.
"Low" = SDEXT is active "Low"
"High" = SDEXT is active "High"
This pin is provided with an internal pull-up.
