Input Buffer Supply and Digital Supply Ground
Input Buffer 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.
LVTTL/LVCMOS Red, Green, and Blue Digital Video Data Inputs. Eighteen data bits are loaded
into the input latch on the rising edge of PCLK_IN when DE_IN is high. Internally pulled down to
GND.
LVTTL/LVCMOS Control Data Inputs. Control data are latched on the rising edge of PCLK_IN
when DE_IN is low. Internally pulled down to GND.
Digital 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.
LVTTL/LVCMOS Data-Enable Input. Logic-high selects RGB_IN[17:0] to be latched. Logic-low
selects CNTL_IN[8:0] to be latched. DE_IN must be switching for proper operation. Internally
pulled down to GND.
LVTTL/LVCMOS Parallel Clock Input. Latches data and control inputs and provides the PLL
reference clock. Internally pulled down to GND.
Internally Connected. Leave unconnected for normal operation.
Preemphasis Enable Input. Drive PRE high to enable preemphasis.
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 Power-Down Input. Internally pulled down to GND.
Common-Mode Filter. Optionally connect a capacitor between CMF and LVDSGND to filter
common-mode switching noise.
LVDS Supply Ground
Inverting LVDS Serial-Data Output
Noninverting LVDS Serial-Data Output
LVDS Supply Voltage. Bypass to LVDSGND 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 Frequency Range Select Input. Set to the frequency range that includes the
PCLK_IN frequency as shown in Table 3. Internally pulled down to GND.
LVTTL/LVCMOS Frequency Range Select Input. Set to the frequency range that includes the
PCLK_IN frequency as shown in Table 3. Internally pulled down to GND.
