GENERAL DESCRIPTION
The TDA4650 is a monolitic
integrated multistandard colour
decoder for PAL, SECAM and NTSC
(3.58 and 4.43 MHz) with negative
colour difference output signals. The
colour-difference output signals are
fed to the TDA4660/TDA4661,
Switched capacitor delay line.
MIN.
Gain controlled chrominance
amplifier
ACC demodulation controlled by
system scanning
Internal colour-difference signal
output filters to remove the residual
