PIN DESCRIPTION
+5V for delay circuitry and input amp
Red channel video input
0V for delay circuitry supply
Green channel video input
-5V for input amp
Blue channel video input
Chip Enable input, active high: logical high enables chip, low disables chip
Serial Enable input, active low: logical low enables serial communication
Serial Data input, logic threshold 1.2V: data to be programmed into chip
Serial Clock input: Clock to enter data; logical; data written on negative edge
Blue channel video output
-5V for video output buffers
Green channel video output
0V reference for input and output buffers
Red channel video output
+5V for video output buffers
Blue channel phase detector output
Green channel phase detector output
Red channel phase detector output
Gain Select Input: logical high = 2x (+6dB), logical low = 1x (0dB)
MUST be tied to -5V. For best thermal conductivity also tie to a larger -5V copper plane (inner
or bottom). Use many vias to minimize thermal resistance between thermal pad and copper
plane. Do not connect to GND - connection to GND is equivalent to shorting the -5V and GND
planes together.
