NXP Semiconductors
TDA9897; TDA9898
Multistandard hybrid IF processing
I Optimized AGC modes for negative modulation; e.g. very fast reaction time for VIF and
SIF
I Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit
Digital-to-Analog Converter (DAC); AFC bits can be read-out via I2C-bus
I High precise Tuner AGC (TAGC) TakeOver Point (TOP) for negative modulated
standards; TOP adjust via I2C-bus
I TAGC TOP for positive standards and Received Signal Strength Indication (RSSI);
adjustable via I2C-bus or alternatively by potentiometer
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)
I SIF AGC for gain controlled SIF amplier and high-performance single-reference
Quasi Split Sound (QSS) mixer
I Fully integrated sound BP lter supporting any ATV standard
I Optional use of external FM or AM sound BP lter
I AM sound demodulation for L and L-accent standard
I Alignment-free selective FM Phase-Locked Loop (PLL) demodulator with high linearity
and low noise; external FM input
I Port function
I VIF AGC voltage monitor output or port function
I TAGC voltage monitor output or port function
I VIF AFC current or tuner, VIF, SIF or FM AGC voltage monitor output
I 2nd SIF output, gain controlled by internal SIF AGC or by internal FM carrier AGC for
Digital Signal Processor (DSP)
I Fully integrated BP lter for 2nd SIF at 4.5 MHz, 5.5 MHz, 6.0 MHz or 6.5 MHz
2.3 Digital TV processing
I Applicable for terrestrial and cable TV reception
I 70 dB variable gain wideband IF amplier (AC-coupled)
I Gain control via external control voltage (0 V to 3 V)
I 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
I DVB downconversion with integrated selectivity for Low IF (LIF)
I Integrated anti-aliasing tracking low-pass lter
I Fully integrated synthesizer controlled oscillator with excellent phase noise
performance
I Synthesizer frequencies for a wide range of world wide DVB standards (for IF center
frequencies of e.g. 34.5 MHz, 36 MHz, 44 MHz and 57 MHz)
I TAGC detector for independent tuner gain control loop applications
I TAGC operating as peak detector, fast reaction time due to additional speed-up
detector
I Port function
I TAGC voltage monitor output
