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
