3. Applications
TDA8296
Product data sheet
Gated IF AGC acting on black level by using H/V PLL or peak IF AGC (I
selectable)
Internal digital logarithmic IF AGC amplifier with up to 48 dB gain and 68 dB control
range
Peak search tuner IF AGC for optimal adaptive drive of the IF ADC
Switchable IF PLL and IF AGC loop bandwidths
Precise AFC and lock detector
Accurate group delay equalization for all standards
Very robust IF demodulator coping with adverse field conditions
Wide PLL pull-in range up to ±1 660 kHz (I
CVBS and SSIF or audio output with simple postfilter (capacitor only)
CVBS gain levelling stage to provide nearly constant signal amplitude during over
modulation
Video equalizer with eight settings
Nyquist filter in video baseband
Excellent video S/N (typically 60 dB weighted)
High selectivity video low-pass filter for all standards
Low video into sound crosstalk
SSIF AGC
Sound performance comparable to QSS single reference concepts
AM/FM mono sound demodulator
Switchable de-emphasis
Excellent FM sound
Good AM sound
High FM Deviation mode for China
Preprocessing of FM radio (mono and stereo) with highly selective digital band-pass
filter
No ceramic filter or external components needed for FM radio
FM radio available in mono
Automatic or forced mute for mono sound
Automatic or forced blank for video
Mostly digital FIR filter implementation (NSC notches and video low-pass filters)
Three GPIO pins
Power-On Reset (POR) block for reliable power-up behavior
Very low total power dissipation (typically 150 mW)
No power sequence requirement
Standby mode (typically 5 mW)
40-pin HVQFN package
CMOS technology (0.090 μm 1.2 V and 3.3 V)
TV applications
Recording
