SAA7151B Overview
The SAA7151B is a digital multistandard colour-decoder having two 8-bit input channels, one for CVBS or Y, the other for chrominance or time-multiplexed colour-difference signals. 5.5 250 TTL-patible TTL-patible 70 °C V mA UNIT ORDERING INFORMATION EXTENDED TYPE NUMBER SAA7151B Note 1. Philips Semiconductors Product specification Digital multistandard colour decoder with SCART interface.
SAA7151B Key Features
- 8-bit performance on chip for luminance and chrominance signal processing for PAL, NTSC and SECAM standards
- Separate 8-bit luminance and 8-bit chrominance input signals from Y/C, CVBS, S-Video (S-VHS or Hi8) sources
- SCART signal insertion by means of RGB/YUV convertion; fast switch handling
- Horizontal and vertical sync detection for all standards
- Real time control output RTCO
- Fast sync recovery of vertical blanking for VCR signals (bottom flutter pensation)
- Controls via the I2C-bus
- User programmable aperture correction (horizontal peaking)
- Cross-colour reduction by chrominance b-filtering (NTSC) or by special cross-colour cancellation (SECAM)
- 8-bit quantization of output signals in 4:1:1 or 4:2:2 formats
