VIF Automatic Gain Control (AGC) detector for gain control; operating as a peak sync
detector for negative modulated signals and as a peak white detector for positive
modulated signals
Optimized AGC modes for negative modulation; e.g. very fast reaction time for VIF and
SIF
External VIF AGC access for car mobile applications; enable function via control port
Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit
Digital-to-Analog Converter (DAC); AFC bits can be read-out via I
High precise Tuner AGC (TAGC) TakeOver Point (TOP) for negative modulated
standards; TOP adjust via I
TAGC TOP for positive standards and Received Signal Strength Indication (RSSI);
adjustable via I
Fully integrated Sound Carrier (SC) trap for any ATV standard (SC at 4.5 MHz,
5.5 MHz, 6.0 MHz and 6.5 MHz)
SIF AGC for gain controlled SIF amplifier and high-performance single-reference
Quasi Split Sound (QSS) mixer
True Split Sound (TSS) mode; picture carrier independent sound demodulation for car
mobile applications
Fully integrated sound BP filter supporting any ATV standard
Optional use of external FM sound BP filter
AM sound demodulation for L and L-accent standard
Alignment-free selective FM Phase-Locked Loop (PLL) demodulator with high linearity
and low noise; external FM input
Weak Audio Frequency Processing (WAFP) in the event of FM audio; audio gain and
bandwidth dependent on received signal quality
VIF AGC voltage monitor output or port function
VIF AFC current or tuner, SIF or FM AGC voltage or WAFP voltage monitor output
Buffered SIF wide-band output, gain controlled by internal SIF AGC
2nd SIF output, gain controlled by internal SIF AGC or by internal FM carrier AGC for
Digital Signal Processor (DSP)
Fully integrated BP filter for 2nd SIF at 4.5 MHz, 5.5 MHz, 6.0 MHz or 6.5 MHz
Applicable for terrestrial and cable TV reception
70 dB variable gain wide-band IF amplifier (AC-coupled)
Gain control via external control voltage (0 V to 3 V)
2 V (p-p) differential low IF (downconverted) output or 1 V (p-p) 1st IF output for direct
Analog-to-Digital Converter (ADC) interfacing
DVB downconversion with integrated selectivity for Low IF (LIF)/Zero IF (ZIF)
Integrated anti-aliasing tracking low-pass filter
Fully integrated synthesizer controlled oscillator with excellent phase noise
performance
Synthesizer frequencies for a wide range of world wide DVB standards (for IF center
frequencies of 34.5 MHz, 36 MHz, 44 MHz and 57 MHz)
All DVB bandwidth ranges supported (including ZIF I/Q)
TAGC detector for independent tuner gain control loop applications
