Digital IF demodulation for all analog TV standards worldwide (M/N, B/G/H, D/K, I, L and L-accent standard)
Multistandard true synchronous demodulation with active carrier regeneration
Alignment-free
16 MHz typical reference frequency input (from low IF tuner) or operating as crystal oscillator
Internal PLL synthesizer which allows the use of a low-cost crystal (typically 16 MHz)
Especially suited for the NXP Silicon Tuner TDA8275A or TDA1827x
No SAW filter needed
Low application effort and external component count in combination with the TDA8275A or TDA1827x
Pin compatible with predecessor TDA8290
Simple upgrade of TDA8290 possible
12-bit IF ADC on chip running with 54 MHz or 27 MHz
Two 10-bit DACs on chip for CVBS and SSIF or audio
Easy programming for I²C-bus
High flexibility due to various I²C-bus programming registers
I²C-bus interface and I²C-bus feed-through for tuner programming
Four I²C-bus addresses selectable via two external pins
Gated IF AGC acting on black level by using H/V PLL or peak IF AGC (I²C-bus 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 1660 kHz (I²C-bus selectable)
CVBS and SSIF or audio output with simple postfilter (capacitor only)
CVBS gain levelling stage to provide nearly constant signal amplitude during overmodulation
Video equalizer with eight settings
Nyquist filter in video baseband
Excellent video S/N (typically 62 dB weighted)
High selectivity video low-pass filter for all standards
Low video into sound crosstalk
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
Low total power dissipation (typically 465 mW)
Standby mode (typically 7 mW)
40-pin HVQFN package
CMOS technology (0.12 m 1.2 V and 3.3 V)

TDA8295HN/C2,518
