Rising or Falling Latch Edge Select. LVTTL/LVCMOS input. Selects the edge of PCLK_OUT
for latching data into the next chip. Set R/F = high for a rising latch edge. Set R/F = low for a
falling latch edge. Internally pulled down to GND.
LVTTL/LVCMOS Range Select Input. Set to the range that includes the serializer parallel
clock input frequency. Internally pulled down to GND.

LVDS Supply Ground
PLL Supply Ground
PLL Supply Voltage. Bypass to PLLGND with 0.1µF and 0.001µF capacitors in parallel as
close to the device as possible with the smallest value capacitor closest to the supply pin.
LVTTL/LVCMOS Range Select Input. Set to the range that includes the serializer parallel
clock input frequency. Internal pulldown to GND.
Digital Supply Ground
Digital Supply Voltage. Supply for LVTTL/LVCMOS inputs and digital circuits. Bypass to
GND with 0.1µF and 0.001µF capacitors in parallel as close to the device as possible with
the smallest value capacitor closest to the supply pin.
LVTTL/LVCMOS Reference Clock Input. Apply a reference clock that is within ±2% of the
serializer PCLK_IN frequency. Internally pulled down to GND.
LVTTL/LVCMOS Power-Down Input. Internally pulled down to GND.
LV TTL/LV C M OS S p r ead - S p ectr um Inp ut. S S sel ects the fr eq uency sp r ead of P C LK_O U T and
outp ut d ata r el ati ve to P C LK_IN . D r i ve S S hi g h for 4% sp r ead and p ul l l ow for 2% sp r ead .
LVTTL/LVCMOS Control Data Outputs. CNTL_OUT[8:0] are latched into the next chip on the
rising or falling edge of PCLK_OUT as selected by R/F when DE_OUT is low, and are held
at the last state when DE_OUT is high.
LVTTL/LVCMOS Data-Enable Output. High indicates RGB_OUT[17:0] are active. Low
indicates CNTL_OUT[8:0] are active.
Output Supply Ground
Output Supply Voltage. Bypass to GND with 0.1µF and 0.001µF capacitors in parallel as
close to the device as possible with the smallest value capacitor closest to the supply pin.
