RTCO contains serialized information about actual clock frequency, subcarrier frequency and PAL/SECAM sequence. - Controls via the I2C-bus - User programmable aperture correction (horizontal peaking) - patible with memory-based Features (line-locked clock) - Cross-colour reduction by chrominance b-filtering (NTSC) or by special cross colour cancellation (SECAM) - 8-bit quantization of input signals - 768/640 active samples per line equals 50/60 Hz (SQP) - The YUV bus supports data rates of 780 × f H equal to 12.2727 MHz for 60 Hz (NTSC-M) and 944 × f H equal to 14.75 MHz for 50 Hz (PAL-B/G, SECAM) in 4 : 1 : 1 or 4 : 2 : 2 formats (via the I2C-bus) - One crystal oscillator of 26.8 MHz 3 QUICK REFERENCE DATA SYMBOL VDD IDD VIL VOL Tamb 4 PARAMETER The SAA7191B is a digital multistandard colour decoder suitable for 8-bit...
