Description
RPWDN = Low will put the Receiver in low power, stand-by, mode.
Note: The Receiver PLL will lose lock.(Note 11)
REN = Low will disable the Receiver outputs. Receiver PLL
remains locked. (See LOCK pin description)(Note 11)
Frequency reference clock input for the receiver.

Transmitter reference clock. Used to strobe data at the DIN Inputs
and to drive the transmitter PLL. See TCLK Timing Requirements.
DEN = Low will disable the Transmitter outputs. The transmitter
PLL will remain locked.(Note 11)
SYNC = High will cause the transmitter to ignore the data inputs
and send SYNC patterns to provide a locking reference to
receiver(s). See Functional Description.(Note 11)
Transmitter data inputs.(Note 11)
PLL Ground.
PLL Voltage supply.
Digital Ground.
CMOS, I TPWDN = Low will put the Transmitter in low power, stand-by
mode. Note: The transmitter PLL will lose lock.(Note 11)
Digital Voltage Supplies.
CMOS, O Receiver Outputs.
CMOS, O Recovered Clock. Parallel data rate clock recovered from
embedded clock. Used to strobe ROUT (0:17). LVCMOS Level
output.
CMOS, O LOCK indicates the status of the receiver PLL. LOCK = H -
receiver PLL is unlocked, LOCK = L - receiver PLL is locked.
PLL Grounds.
PLL Voltage Supplies.
CMOS, I LINE_LE = High enables the receiver loopback mode. Data
received at the RIN± inputs is fed back through the DO±
outputs.(Note 11)
CMOS, I LOCAL_LE = High enables the transmitter loopback mode. Data
received at the DIN inputs is fed back through the ROUT
outputs.(Note 11)
Note 11: Input defaults to "low" state when left open due to an internal on-chip pull-down circuit.
