Description
Transmitter LVDS Inverting Output
Transmitter reference clock. Used to strobe data at the DIN Inputs and
to drive the transmitter PLL. See SERIALIZER TIMING
REQUIREMENTS FOR TCLK
Configuration pin - strap or tie this pin to High with pull-up resistor. No-
connect or Low reserved for future use.
DEN = Low will disable the Transmitter outputs. The transmitter PLL will
remain locked.⁽¹⁾
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.⁽¹⁾
Transmitter data inputs.⁽¹⁾
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.⁽²⁾
Digital Voltage Supplies.
CMOS, O Receiver Outputs.
CMOS, O Recovered Clock. Parallel data rate clock recovered from embedded
clock. Used to strobe ROUT (0:15). 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.⁽²⁾
CMOS, I LOCAL_LE = High enables the transmitter loopback mode. Date
received at the DIN inputs is fed back through the ROUT outputs.⁽²⁾
(2) Input defaults to "low" state when left open due to internal pull-device.
