It converts a wide-band analog signal (such as a video signal) to digital data at sampling rates up to 20 MSPS minimum. The TLC5733 contains a feed-back type high-precision clamp circuit for each ADC channel for video (YUV) applications and a clamp pulse generator that detects COMPOSITE SYNC† pulses automatically. A clamp pulse can also be supplied externally. The output data format multiplexer selects a ratio of Y:U:V of 4:4:4, 4:1:1, or 4:2:2. For RGB applications, the 4:4:4 output format without clamp function can be used. The TLC5733 is characterized for operation from – 20°C to 75°C.
