Working Principles

SI2168-A20-GM operates by receiving the RF signal from the antenna through the RFIN pin. The integrated RF tuner then selects the desired frequency and converts it to an intermediate frequency (IF). The demodulator section decodes the modulated digital TV signal, performing error correction and equalization to ensure accurate data recovery. The processed signal is then available at the IFOUT pin for further processing by external audio and video components.
