TDA18271HD

The TDA18271HD is designed as one kind of Hybrid (analog and digital) Silicon Tuner device that integrates the overall tuning function, including selectivity, and 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).

Features of the TDA18271HD are:(1)Fully integrated RF tracking filters for unwanted signal suppression; (2)Fully integrated IF selectivity (no need for external SAW filters); (3)Worldwide multistandard terrestrial (all analog and digital worldwide terrestrial standards supported); (4)Integrated loop-through and slave tuner output for straightforward multi-Silicon Tuner application; (5)Fully integrated oscillators with no external components; (6)Alignment free; (7)Integrated wide-band gain control; (8)Single 3.3 V power supply; (9)Low power consumption; (10)Crystal oscillator output buffer (16 MHz) for single crystal applications; (11)I2C-bus interface compatible with 3.3 V and 5 V microcontrollers; (12)Three Standby modes; (13)RoHS packaging.

The absolute maximum ratings of the TDA18271HD can be summarized as:(1)supply voltage: 3.13 to +3.47 V;(2)supply current: 180 to 290 mA;(3)storage temperature: -40 to +150 °C;(4)junction temperature: 125 °C;(5)ambient temperature: -20 °C.
