Preliminary specification
Generic multi-standard decoder
TDA4657
FEATURES
Low voltage (8 V)
Low power dissipation (250 mW)
Automatic standard recognition
No adjustments required
Reduced external components
Not all time constants integrated
(ACC, SECAM de-emphasis).
GENERAL DESCRIPTION
The TDA4657 is a monolithic integrated multi-standard
colour decoder for PAL, SECAM and NTSC 4.43 MHz with
negative colour difference output signals. It is adapted to
the integrated baseband delay line TDA4660/61.
