KKA4661 Overview
The KKA4661 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.
KKA4661 Key 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
- 350 320 54
