NXP Semiconductors SAA7199B
The SAA7199B encodes digital baseband colour/video data into analog Y, C and CVBS signals (S-video included). The circuit can be used in a square pixel or in a consumer TV application.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 composite 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
● Stable GENLOCK operation in VCR standard playback mode
● Optional still video capture extension
● Three suitable video 9-bit digital-to-analog converters
● Composite analog output signals CVBS, Y and C for PAL/NTSC
● Line 21 data insertion possible. QUICK REFERENCE DATA SYMBOL VDDD VDDA IP(tot) VI Vo RL ILE DLE Tamb PARAMETER digital supply voltage (pins 2, 2...
