1 / 10 page 1. General description The TDA18272HN is a Silicon Tuner designed for terrestrial and cable TV reception for both analog and digital signals. TDA18272HN/M (Master) is to be used as a stand-alone tuner IC or Master in dual tuner application. TDA18272HN/S (Slave) is only to be used as Slave Silicon Tuner in dual tuner application. The TDA18272HN supports all analog and digital TV standards and delivers a LOW IF (LIF) signal to a demodulator for analog TV and/or a channel demodulator for digital TV. 2. Features and benefits Fully integrated IF selectivity; eliminating the need for external SAW filters Worldwide multistandard terrestrial and cable Fully integrated oscillators Alignment free Single 3.3 V supply voltage Integrated wideband gain control Crystal oscillator output buffer (16 MHz) for single crystal applications I2C-bus interface compatible with 3.3 V microcontrollers Slave tuner output function to drive second (slave) Silicon Tuner Easy programming 5 ms tuning time LIF channel center frequency output ranging from 3 MHz to 5 MHz 1.7 MHz, 6 MHz, 7 MHz, 8 MHz and 10 MHz channel bandwidths Ready for DVB-T2 RoHS compliant 3.
