TDA8758 Overview
The TDA8758 is an 8-bit video high-speed low-power analog-to-digital conversion (ADC) interface for YC and CVBS signal processing. It converts 1-of-3 CVBS input signals or 1-of-2 YC input signals into binary or two’s plement words at a sampling rate of 32 MHz. All analog signal inputs are digitally clamped and an ADC interface is provided on the Y/CVBS channel.
