Projects - RGB to S-Video Converter - Circuit

The circuit schematic for my PAL RGB -> S-Video converter is below. You probably want to look at the notes about it too. If you want to print it out then grab the PostScript version or the gschem version.

Circuit diagram

All Vcc connections are +5v

C25, C26, C29, C30, C31, C32 220uF Electrolytic
R1 4.7M
R2, R3, R4, R10 1K Pot
R5 47K
R6 16K 1%
R7, R8, R9, R36, R37, R38 75 Ohm

U1 CXA1645P Video Encoder
U2 LM1881N Video Sync Separator
U3 74HCT04 Hex Inverter
XTL1 4.433619MHz Parallel-Cut Crystal

The CXA1645P seems to be reasonably difficult to get hold of according to the emails I get about this circuit. I got it from RS Components.
