The ADV7177/ADV7178 is an integrated digital video encoder that converts Digital CCIR-601 4:2:2 8- or 16-bit component video data into a standard analog baseband television signal compatible with worldwide standards. The 4:2:2 YUV video data is interpolated to two times the pixel rate. The color-difference components (UV) are quadrature modulated using a subcarrier frequency generated by an on-chip 32-bit digital synthesizer (also running at two times the pixel rate). The two times pixel rate sampling allows for better signal-to-noise ratio. A 32-bit DDS with a 9-bit look-up table produces a superior subcarrier in terms of both frequency and phase. In addition to the composite output signal, there is the facility to output S-Video (Y/C) video, YUV or RGB video. * ITU-R BT601/656 YCrCb to PAL/NTSC video encoder * High quality, 9-bit video DACs * Integral nonlinearity <1 LSB at 9 bits * NTSC-M, PAL-M/N, PAL-B/D/G/H/I * Single 27 MHz crystal/clock required (±2 oversampling) * 75 dB video SNR * 32-bit direct digital synthesizer for color subcarrier * Multistandard video output support: Composite (CVBS) Component S-video (Y/C) Component YUV or RGB
