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) • Compatible with memory-based features (line-locked clock) • Cross-colour reduction by chrominance comb-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 × fH equal to 12.
2727 MHz for 60 Hz (NTSC-M) and 944 × fH 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.
