SAA7199B Description
The SAA7199B encodes digital baseband colour/video data into analog Y, C and CVBS signals (S-video included). Pixel clock and data are line-locked to the horizontal scanning frequency of the video signal. The circuit can be used in a square pixel or in a consumer TV application.
SAA7199B Key Features
- Monolithic integrated CMOS video encoder circuit
- Standard MPU (12 lines) and I2C-bus interfaces for controls
- Three 8-bit signal inputs PD7 to PD0 for RGB respectively YUV or indexed colour signals (Tables 19 to 26)
- Square pixel and CCIR input data rates
- Band limited posite sync pulses
- Three 256 × 8 colour look-up tables (CLUTs) for example for gamma correction
- External subcarrier from a digital decoder (SAA7151B or SAA7191B)
- Multi-purpose key for real time format switching
- Autonomous internal blanking
- Optional GENLOCK operation with adjustable horizontal sync timing and adjustable subcarrier phase
