A to D Input Module (Optional)

The optional A to D Input module is an 8 input board that replaces a “standard” 8 input HD/SD
board.

This board will take a valid NTSC or PAL composite video signal and convert it to 270 Mbps
video.

There are 8 A to D converters on each board and each of them operates independently.

Each input will automatically detect the incoming signal format (525 NTSC or 625 PAL) and
output 270Mbps digital video.

Input Impedance: 75 ohm

Quantization: 10 bits

Differential gain: less than +/- 0.7 % @ 3.58 MHz or 4.443 MHz

Differential phase: less than +/- 0.7 degrees @ 3.58 MHz or 4.443 MHz

Luma non-linearity: less than +/- 0.7% @ 3.58 MHz or 4.443 MHz

SNR unweighted: > 54 db using Luma flat field test signal

Hue Accuracy: better than 1 degree

Color Saturation Accuracy: better than 1%
