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.

Key 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.
