ILA4661
ILA4661 is Baseband Delay Line manufactured by IK Semiconductor.
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 b 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)
- b 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
