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 • Clamping of AC-coupled input signals ± (R-Y) and ± (B-Y) QUICK REFERENCE DATA Parameter Analogy supply current, mA Digital supp...
