Abstract
In one example, a semiconductor die includes multi-standard, multi-channel expandable television/satellite receiver that can be flexibly implemented in a number of different configurations to enable incorporation into a plurality of different systems. The semiconductor die may include multiple tuners to receive and tune a terrestrial radio frequency (RF) signal and a satellite RF signal. These tuners may include different frequency synthesizers including voltage controlled oscillators (VCOs) to generate VCO signals at different frequencies, mixers to downconvert the RF signals to baseband signals using the VCO signals. In an implementation, the semiconductor die may further include shared circuitry coupled to the tuners to digitize, process and demodulate the baseband signals.
