描述 Description

The MxL603 is a highly integrated, low power silicon tuner IC, that targets all global digital cable and terrestrial standards. The high performance MxL603 is fully compliant with the latest specifications for DVB-T and DVB-T2 (including Nordig 2.6 and DTG D-Book V10.0), ATSC A/74:2010, ATSC 3.0, ISDB-T 13-Segment, SBTVD-T(Brazil), DTMB (China) and cable (DOCSIS 2.0/3.0, J.83 Annex A/B/C) reception.

?



The MxL603 supports an input tuning range from 44MHz to 1002MHz. A differential 75Ω RF input signal is filtered and converted to a programmable IF output up to 44MHz. The AGC, LO generation, channel selection, and Loop-Through (LT) output functions are completely integrated on the chip, which simplifies board-level design. All functions of the IC can be controlled via an I2C interface. Driver integration with all commercially available third-party demodulators is made easy through the use of simple software APIs.

?Immunity to LTE and WiFi interference is optimized and provides significant margin above industry requirements. The high level of integration enables a very compact, cost effective design with few external components, low BOM costs, and low power consumption.

The MxL603 is available in a 4 mm x 4 mm x 0.85mm3 24-pin QFN package.
