TDA18218HN

The TDA18218HN is designed as one kind of single-chip direct conversion Silicon Tuner IC device that integrates the overall tuning function, including selectivity and provides a low-IF output signal. And this device requires only one single 16 MHz crystal for clock generation. A clock signal is available on crystal oscillator output pins (XTO_P / XTO_N) to synchronize the channel decoder.

Features of the TDA18218HN are:(1)Fully integrated IF selectivity; eliminating the need for external SAW filters; (2)Fully integrated oscillators with no external components; (3)Integrated wideband gain control; (4)Alignment free; (5)RF loop-through for easy implementation in the Set-Top Box (STB); (6)Integrated die thermal sensor; (7)Single 3.3 V power supply; (8)Low power consumption (750 mW); (9)Crystal oscillator output buffer (16 MHz) for single crystal applications; (10)I2C-bus interface compatible with 3.3 V and 5 V microcontrollers; (11)Three Standby modes; (12)RoHS packaging.

The absolute maximum ratings of the TDA18218HN can be summarized as:(1)supply voltage: -0.3 to +3.60 V;(2)input voltage: -0.3 to +5.5 V;(3)storage temperature: -40 to +150 ;(4)junction temperature: 95 ;(5)electrostatic discharge voltage: +/-2 kV or 200 V.
