The integrated delay line circuit U3666M is suitable for all chroma decoders with baseband color-difference outputs. It is suitable for PAL-, SECAM- and NTSC-signals as well. The U3666M contains two separate delay lines for processing (RY)-output and (BY)-output separately. The delay is performed by internally switched capacitors. On-chip postfiltering avoids the need for external filter components. In the case of the U3666M, the postfilter is tuned to Bessel-characteristic.
