SAA7103H/V4,557

Encoders, Decoders, Converters Overview

The SAA7103H/V4,557 is a digital video encoder designed to convert PC graphics data into PAL or NTSC video signals. It supports maximum resolutions of 800 × 600 at 50 Hz or 60 Hz frame rates. The device features an integrated programmable scaler and anti-flicker filter for flicker-free TV displays via CVBS or S-video outputs. It includes three 10-bit Digital-to-Analog Converters (DACs) operating at a 27 MHz sample rate. The unit operates on a 3.3 V supply with 5 V tolerant I/Os and utilizes a Fast I2C-bus control port.
