TECHNICAL DATA
BASEBAND DELAY LINE
GENERAL DESCRIPTION
The ILA4661 is an integrated baseband delay line circuit with one line delay. It is
suitable for decoders with colour-difference signal outputs ± (R-Y) and ± (B-Y).
Device is functionally identical to the TDA4661 Philips.
FEATURES
Two comb filters, using the switched-capacitor technique, for one line delay time (64
µS)
3 MHz internal clock signal derived from a 6 MHz CCO, line-locked by the sandcastle
pulse (64 µS line)
Comb filtering functions for NTSC colour-difference signals to suppress cross-colour
mClamping of AC-coupled input signals ± (R-Y) and ± (B-Y)
