Composite PAL/NTSC to Serial Digital Module.
 High Performance Conversion
 Adaptive Comb filter decoding
 Minimal conversion delay
 Auto NTSC/PAL detection
 Six cards in a 1U frame

This module converts analogue PAL or NTSC composite video
to 270 Mb/s component serial digital video. The PAL/NTSC
decoder is fully digital providing excellent stability and quality.
The input is sampled at 13.5 MHz and then filtered digitally to
separate the luminance and chrominance information. A
remote control option enables adjustment of the basic video
parameters such as gain, black level, etc.

The CSD203 is part of our modular Series 200 range.

Input:
Analogue Composite PAL or NTSC.
Input levels - 0.7V (100IRE) video, 0.3V (40IRE) sync.
Input present LED.

Outputs:
3 x 270Mb/s serial digital to EBU Tech. 3267-E, (SMPTE 259M)
Loop through of analogue video provided on BNC.

Conversion:
The composite signal is digitised to 10 bit resolution.
A 3 line adaptive comb decoder is used to decode the composite signal. This can be
turned off to give simple band pass filtering.
Frequency Response within +/-1dB to 5.5 MHz (with comb dec)
Differential Gain Error <1%
Differential Phase Error <1 deg

Adjustments:
Loop through of analogue video or 75R internal terminator can be set by on board link.
DIP switches at the front of the board allow -
Comb decode or simple band pass decode control.
Automatic standard (PAL /NTSC) select can be disabled.
Select Pedestal removal in 525 operation.
VBI can be passed through or blanked off.
Rotary switch allows adjustment of horizontal positioning

Physical:
Eurocard size module (220x100mm) for mounting in Microvideo's 1U and 3U frames
