TDA9899
Multistandard hybrid IF processing including car mobile
n 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
n Optimized AGC modes for negative modulation; e.g. very fast reaction time for VIF and
SIF
n External VIF AGC access for car mobile applications; enable function via control port
n Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit
Digital-to-Analog Converter (DAC); AFC bits can be read-out via I
2
C-bus
n High precise Tuner AGC (TAGC) TakeOver Point (TOP) for negative modulated
standards; TOP adjust via I
2
C-bus
n TAGC TOP for positive standards and Received Signal Strength Indication (RSSI);
adjustable via I
2
C-bus or alternatively by potentiometer
n 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)
n SIF AGC for gain controlled SIF amplifier and high-performance single-reference
Quasi Split Sound (QSS) mixer
n True Split Sound (TSS) mode; picture carrier independent sound demodulation for car
mobile applications
n Fully integrated sound BP filter supporting any ATV standard
n Optional use of external FM sound BP filter
n AM sound demodulation for L and L-accent standard
n Alignment-free selective FM Phase-Locked Loop (PLL) demodulator with high linearity
and low noise; external FM input
n Weak Audio Frequency Processing (WAFP) in the event of FM audio; audio gain and
bandwidth dependent on received signal quality
n VIF AGC voltage monitor output or port function
n VIF AFC current or tuner, SIF or FM AGC voltage or WAFP voltage monitor output
n Buffered SIF wide-band output, gain controlled by internal SIF AGC
n 2nd SIF output, gain controlled by internal SIF AGC or by internal FM carrier AGC for
Digital Signal Processor (DSP)
n Fully integrated BP filter for 2nd SIF at 4.5 MHz, 5.5 MHz, 6.0 MHz or 6.5 MHz
2.3 Digital TV processing
n Applicable for terrestrial and cable TV reception
n 70 dB variable gain wide-band IF amplifier (AC-coupled)
n Gain control via external control voltage (0 V to 3 V)
n 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
n DVB downconversion with integrated selectivity for Low IF (LIF)/Zero IF (ZIF)
n Integrated anti-aliasing tracking low-pass filter
n Fully integrated synthesizer controlled oscillator with excellent phase noise
performance
n 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)
n All DVB bandwidth ranges supported (including ZIF I/Q)
n TAGC detector for independent tuner gain control loop applications
