MXL5003S DATASHEET REV. 1.0 MAXLINEAR MXL5003S DIGITAL SILICON IC TUNER General Description The Mx L5003S is an integrated tuner IC, which meets the specifications of digital (DVB-T, DVBH, ISDB-T 13-seg, ATSC, and 64/256-QAM) TV standards. It enables a manufacturer to design a TV tuner module with a small footprint, low bill-of-materials cost, and low power consumption. The tuner IC can be configured through I2C interface to change modes for receiving different standards. It takes an input from a 75Ω antenna or cable and produces a programmable channel-selected IF output up to 57MHz. Gain control, LO generation, and channel selectivity functions are pletely integrated on the chip, which simplifies board-level design. The nominal power supply is 1.8V. If 1.8V supply is not available, an on-chip regulator can provide the 1.8V supply from a 2.3V to 3.6V supply. The Mx L5003S is available in a 6 x 6 mm2 40-pin QFN package. Other package options are available.
