General
- 5 V supply voltage
- I²C-bus control over all functions
- Four I²C-bus addresses provided; selection by programmable Module Address (MAD)
- Three I²C-bus voltage level supported; selection via pin BVS
- Separate gain controlled amplifiers with input selector and conversion for incoming IF [analog Vision IF (VIF) or Sound IF (SIF) or Digital TV (DTV)] allows the use of different filter shapes and bandwidths
- All conventional ATV standards applicable by using DTV bandwidth window [Band-Pass (BP)] filter
- Easy to use default settings for almost every standard provided, selectable via I²C-bus
- Two 4 MHz reference frequency stages; the first one operates either as crystal oscillator or as optional signal input, the second one either as external signal input or as buffered reference frequency output
- Stabilizer circuit for ripple rejection and to achieve constant output signals
- Smallest size, simplest application
- ElectroStatic Discharge (ESD) protection for all pins
Analog TV processing
- Gain controlled wide-band VIF amplifier; AC-coupled
- Multistandard true synchronous demodulation with active carrier regeneration: very linear demodulation, good intermodulation figures, reduced harmonics and excellent pulse response
- Internal Nyquist slope processing; switch-off able for alternative use of inexpensive Nyquist slope SAW filter with additive video noise improvement
- Separate passive video detector; monitor output for antenna diversity applications
- Gated phase detector for L and L-accent standards
- Fully integrated VIF Voltage-Controlled Oscillator (VCO), alignment-free, frequencies switchable for all negative and positive modulated standards via I²C-bus

- 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 I²C-bus
- High precise Tuner AGC (TAGC) TakeOver Point (TOP) for negative modulated standards; TOP adjust via I²C-bus
- TAGC TOP for positive standards and Received Signal Strength Indication (RSSI); adjustable via I²C-bus or alternatively by potentiometer
- 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
Digital TV processing
- 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
- TAGC operating as peak detector, fast reaction time due to additional speed-up detector
- Port function
- TAGC voltage monitor output
Dual mode
- Fully performed DTV processing and additional ATV video signal processing in parallel, but with reduced performance, for very fast channel scan
- VIF AGC voltage monitor output or port function
- VIF AFC current monitor output or TAGC voltage output
FM radio mode
- Gain controlled wide-band Radio IF (RIF) amplifier; AC-coupled
