Multistandard multimedia IF-PLL and FM radio demodulator

Philips Electronics 

Philips Semiconductors

Multistandard multimedia IF-PLL and FM

radio demodulator

Preliminary specification

TDA9816M

FEATURES

• 5 V supply voltage

• Gain controlled wideband Video IF (VIF) amplifier

(AC-coupled)

• True synchronous demodulation with active carrier

regeneration (very linear demodulation, good

intermodulation figures, reduced harmonics,

excellent pulse response)

• Robustness for over-modulation better than 105% due

to gated phase detector at L/L accent standard and PLL

bandwidth control for negative modulation standards

• VCO (Voltage Controlled Oscillator) frequency can be

switched between L and L accent (alignment external)

picture carrier frequency

• VIF AGC (Automatic Gain Control) detector for gain

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

peak white detector for L; signal controlled reaction time

for L

• Tuner AGC with adjustable TakeOver Point (TOP)

• AFC (Automatic Frequency Control) detector without

extra reference circuit

• AC-coupled limiting amplifier for sound intercarrier

signal

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

demodulator with high linearity; integrated de-emphasis

resistor

• Integrated level detector

• Alignment-free FM radio AFC detector with external

resonator

• RIF (Radio IF) amplifier for 10.7 MHz

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

Split Sound) 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

• AM demodulator without extra reference circuit

• Stabilizer circuit for ripple rejection and to achieve

constant output signals

• ESD (Electrostatic Discharge) protection for all pins.

GENERAL DESCRIPTION

The TDA9816M is an integrated circuit for multistandard

vision IF signal processing, sound AM and FM

demodulation and FM radio demodulation in multimedia

sets.
