The outputs are capable of driving doubly terminated 75 ohm loads with standard video levels. The device will also accept YUV data. Progressive scan (non-interlaced fields) video display is available in both NTSC and PAL modes. The output pixel rate is approximately 7 times Fsc (color subcarrier frequency) for NTSC (6.6 times Fsc for PAL) which is approximately 25MHz. Input pixel rate is half this frequency; approximately 12.5MHz. All the necessary synchronization signals are generated internally. Digital horizontal and vertical sync outputs are available for use by the host system. The rise and fall times of sync, burst envelope and video blanking are internally controlled to be within composite video specifications. Two 8-bit digital to analog converters (DACs) ar...
