Product speciﬁcation

Single/multistandard VIF/SIF-PLL and

FM-PLL/AM demodulators

TDA9817; TDA9818

FEATURES

• AC-coupled limiter amplifier for sound intercarrier signal

• Alignment-free FM Phase-Locked Loop (PLL)

demodulator with high linearity

• 5 V supply voltage

• Applicable for Intermediate Frequencies (IFs) of

• Sound IF (SIF) input for single reference Quasi Split

Sound (QSS) mode (PLL controlled); SIF AGC detector

for gain controlled SIF amplifier; single reference QSS

mixer able to operate in high performance single

reference QSS mode and in intercarrier mode

38.9, 45.75 and 58.75 MHz

• Gain controlled wide band Video IF (VIF) amplifier

(AC-coupled)

• True synchronous demodulation with active carrier

regeneration (very linear demodulation, good

intermodulation figures, reduced harmonics and

excellent pulse response)

• AM demodulator without extra reference circuit

• Stabilizer circuit for ripple rejection and to achieve

constant output signals

• Robustness for over-modulation better than 105% due

to gated phase detector at L/L accent standard and

PLL-bandwidth control at negative modulated standards

• ElectroStatic Discharge (ESD) protection for all pins.

• Voltage Controlled Oscillator (VCO) frequency

switchable between L and L accent (alignment external)

picture carrier frequency

GENERAL DESCRIPTION

The TDA9817 is an integrated circuit for single standard

vision IF signal processing and FM demodulation.

• VIF Automatic Gain Control (AGC) detector for gain

control, operating as peak sync detector for B/G, peak

white detector for L; signal controlled reaction time for L

The TDA9818 is an integrated circuit for multistandard

vision IF signal processing, sound AM and FM

demodulation.

• Tuner AGC with adjustable TakeOver Point (TOP)

• Automatic Frequency Control (AFC) detector without

extra reference circuit
