Product specification

Baseband delay line

TDA4663T

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 components

• 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

• Output buffer amplifiers.

GENERAL DESCRIPTION

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).
