Can we build one ourselves? You might use a MM5321 TV camera sync generator from National Semiconductor. It is a P-channel MOS LSI device which uses either a 1.26 Mhz or a 2.04545 Mhz clock which can be derived from dividing down a 14.31818 Mhz clock by 7. The device outputs color burst gate, horizontal drive, color burst sync, composite sync, composite blanking, vertical drive, and a field index pulse which can be used to gen lock another 5321. I have breadboarded this device, and it is easy to use and costs about $20.00 . geo
