Product data sheet
1. General description
The TDA18271HD is a Silicon Tuner IC designed mainly for terrestrial analog and digital
TV reception. The TDA18271HD integrates the overall tuning function, including
selectivity.
The TDA18271HD is compatible with all analog and digital TV standards and delivers a
low IF signal to a demodulator (for analog TV) and/or channel decoder (for digital TV).
This specification is based on software version 3.4.
2. Features
I Fully integrated RF tracking filters for unwanted signal suppression
I Fully integrated IF selectivity (no need for external SAW filters)
I Worldwide multistandard terrestrial (all analog and digital worldwide terrestrial
standards supported)
I Integrated loop-through and slave tuner output for straightforward multi-silicon tuner
application
I Fully integrated oscillators with no external components
I Alignment free
I Integrated wide-band gain control
I Single 3.3 V power supply
I Low power consumption
I Crystal oscillator output buffer (16 MHz) for single crystal applications
I I2C-bus interface compatible with 3.3 V and 5 V microcontrollers
I Three Standby modes
I RoHS packaging
3. Applications
3.1 Target applications
I Hybrid (analog and digital TV) for PCTV, DVD-R and TV applications
I Application optimization is described in application notes AN602, AN604 and AN605
