Product speciï¬cation
TDA4662
FEATURES
⢠Two comb filters, using the switched-capacitor
technique, for one line delay time (64 µs)
⢠For PAL and NTSC
⢠Adjustment-free application
⢠Handles negative or positive colour-difference input
signals
⢠Clamping of AC-coupled input signals [±(RâY) and
±(BâY)]
⢠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
⢠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 TDA4662 is an integrated baseband delay line circuit
with one line delay. It is suitable for PAL and NTSC
decoders with colour-difference signal outputs ±(RâY) and
±(BâY).
