Preliminary speciﬁcation

Multistandard VIF-PLL demodulator

and FM-PLL detector

TDA9802

FEATURES

• Suitable for negative and positive vision modulation

• Gain controlled 3-stage IF amplifier; suitable for VIF

frequencies up to 60 MHz

• True synchronous demodulation with active carrier

regeneration (ultra-linear demodulation, good

intermodulation figures, reduced harmonics and

excellent pulse response)

• Peak sync AGC for negative modulation, e.g. B/G

standard

• Peak white AGC for positive modulation, e.g. L standard

• Video amplifier to match sound trap and sound filter

• AGC output voltage for tuner; adjustable take-over point

(TOP)

• AFC detector without extra reference circuit

• Alignment-free FM-PLL detector with high linearity

• Stabilizer circuit for ripple rejection and to achieve

constant output signals

• 5 to 8 V positive supply voltage range, low power

consumption (300 mW at +5 V supply voltage)

GENERAL DESCRIPTION

The TDA9802 is a monolithic integrated circuit for vision

and sound IF signal processing in multistandard TV and

VTR sets.
