IC U3665M Chroma Baseband Delay Line 64

IC Chroma untuk televisi - U3665M
Application In TV sets, the integrated baseband delay line circuit is suitable for decoders with color-difference signal outputs

Description The integrated delay line circuit U3665M is suitable for all chroma decoders with baseband color-difference outputs. It is suitable for PAL-, SECAM- and NTSC-signals as well. The U3665M 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 U3665M, the postfilter is tuned to Bessel-characteristic. A summing circuitry combines the information of adjacent TV-lines, thus giving an interpolated sum for the PAL-system, storing preceeding lines for the SECAMsystem and providing a comb-filtered output for NTSC-signals.

Due to internally generated timing, synchronization is easily done by feeding a line-frequent impulse (usually the SC-impulse) to the sync-input of the IC.
