Multistandard decoder

TDA4555

TDA4556

GENERAL DESCRIPTION

The TDA4555 and TDA4556 are monolithic integrated

multistandard colour decoders for the PAL, SECAM,

NTSC 3,58 MHz and NTSC 4,43 MHz standards. The

difference between the TDA4555 and TDA4556 is the

polarity of the colour difference output signals (B-Y)

and (R-Y).

Features

Chrominance part

• Gain controlled chrominance amplifier for PAL, SECAM

and NTSC

• ACC rectifier circuits (PAL/NTSC, SECAM)

• Burst blanking (PAL) in front of 64 µs glass delay line

• Chrominance output stage for driving the 64 µs glass

delay line (PAL, SECAM)

• Limiter stages for direct and delayed SECAM signal

• SECAM permutator

Demodulator part

• Flyback blanking incorporated in the two synchronous

demodulators (PAL, NTSC)

• PAL switch

• Internal PAL matrix

• Two quadrature demodulators with external reference

tuned circuits (SECAM)

• Internal filtering of residual carrier

• De-emphasis (SECAM)

• Insertion of reference voltages as achromatic value

(SECAM) in the (B-Y) and (R-Y) colour difference output

stages (blanking)

Identiﬁcation part

• Automatic standard recognition by sequential inquiry

• Delay for colour-on and scanning-on

• Reliable SECAM identification by PAL priority circuit

• Forced switch-on of a standard

• Four switching voltages for chrominance filters, traps

and crystals

• Two identification circuits for PAL/SECAM (H/2) and

NTSC

• PAL/SECAM flip-flop

• SECAM identification mode switch (horizontal, vertical

or combined horizontal and vertical)

• Crystal oscillator with divider stages and PLL circuitry

(PAL, NTSC) for double colour subcarrier frequency

• HUE control (NTSC)

• Service switch
