TDA9897; TDA9898

NXP Semiconductors

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 ampliﬁer and high-performance single-reference

Quasi Split Sound (QSS) mixer

I Fully integrated sound BP ﬁlter supporting any ATV standard

I Optional use of external FM sound BP ﬁlter

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 VIF AGC voltage monitor output or port function

I VIF AFC current or tuner, 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 ﬁlter 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 wide-band IF ampliﬁer (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)/Zero IF (ZIF)

I Integrated anti-aliasing tracking low-pass ﬁlter

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 34.5 MHz, 36 MHz, 44 MHz and 57 MHz)

I All DVB bandwidth ranges supported (including ZIF I/Q)

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
