TDA4663T Overview
plastic small outline package; body width 3.9 mm −1 −1 0 − − 1.3 1.3 MIN. GENERAL DESCRIPTION TDA4663T The TDA4663T is an integrated baseband delay line circuit with a delay time of one horizontal line (1H) minus 55 ns (64 µs − 55 ns).
TDA4663T Key Features
- Two delay lines, using the switched-capacitor technique, for a delay time of one horizontal line (1H) minus 55 ns (64 µs
- 55 ns)
- Adjustment-free application
- Handles negative or positive colour-difference input signals
- Clamping of AC-coupled input signals [mostly colour-difference signals ±(R-Y) and ±(B-Y)]
- VCO without external ponents
- 3 MHz internal clock signal derived from a 6 MHz CCO, line-locked by the sandcastle pulse (64 µs line)
- Sample-and-hold circuits and low-pass filters to suppress the 3 MHz clock signal
- 1.3 1.3 MIN. 4.75 4.75
