Product specification
Baseband delay line
TDA4661
FEATURES
Two comb filters, using the switched-capacitor
technique, for one line delay time (64
μ
s)
Adjustment-free application
No crosstalk between SECAM colour carriers (diaphoty)
Handles negative or positive colour-difference input
signals
Clamping of AC-coupled input 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
μ
s line)
Sample-and-hold circuits and low-pass filters to
suppress the 3 MHz clock signal
Addition of delayed and non-delayed output signals
Output buffer amplifiers
Comb filtering functions for NTSC colour-difference
signals to suppress cross-colour.
GENERAL DESCRIPTION
The TDA4661 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).
