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.

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.
