PIN DESCRIPTION
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, 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.
