QUICK REFERENCE DATA SYMBOL VDDD VDDA IP(tot) VI Vo RL ILE DLE Tamb PARAMETER digital supply voltage (pins 2, 21 and 41) analog supply voltage (pins 64, 66, 70 and 72) total supply current input signal levels analog output voltage Y, C and CVBS without load (peak-to-peak value) output load resistance LF integral linearity error in output signal (9-bit DAC) LF differential linearity error in output signal (9-bit DAC) operating ambient temperature - 90 - - 0 MIN. 4.5 4.75 - SAA7199B GENERAL 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.
