SAA7182A and SAA7183A are digital video encoders produced by Philips. They feature CMOS 3.3V devices and 5V input circuits, support PAL/NTSC/SECAM decoded data, and accept data on an 8-bit wide input port. In addition, the product also has three DACs for CVBS, Y and C, as well as RGB output.
The Philips SAA7182A and SAA7183A are monolithic CMOS digital video encoders that convert YUV video data to NTSC, PAL, SECAM, CVBS, S‑Video, and RGB outputs. They support 13.5 MHz pixel frequency, accept MPEG‑decoded data, and include on‑chip DACs, colour‑bar generator, and optional Macrovision copy‑protection.
