SAA7105E/V1/G,518

Encoders, Decoders, Converters Overview

The SAA7105E/V1/G,518 is a digital video encoder designed to convert PC graphics data into PAL or NTSC video signals. It supports resolutions up to 1280 × 1024 progressive and 1920 × 1080 interlaced at 50/60 Hz frame rates. The device features a programmable scaler, anti-flicker filter, and triple 10-bit DACs operating at a 27 MHz sample rate for CVBS, S-video, and RGB outputs. It utilizes a monolithic CMOS process with a 3.3 V supply and 5 V tolerant I/Os, incorporating an on-chip 27 MHz crystal oscillator and a fast I2C-bus control port.
