Baseband Delay Line 64
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 U3666M is suitable for
all chroma decoders with baseband
outputs. It is suitable for PAL-, SECAM- and
NTSC-signals as well. The U3666M contains two
separate delay lines for processing (R–Y)-output and
(B–Y)-output separately. The delay is performed by inter-
nally 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.

A summing circuitry combines the information of
adjacent TV-lines, thus giving an interpolated sum for the
PAL-system, storing preceeding lines for the SECAM-
system 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.
