RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MICROTUNER™ MT2011 SINGLE-CHIP BROADBAND TUNER PRODUCT BRIEF The MicroTuner MT2011 is a fully integrated single-chip tuner, optimized for digital OpenCable compliant STB PRELIMINARY applications. MT2011 Single-Chip Broadband Tuner The MicroTuner™ MT2011 is a fully integrated single-chip tuner, with functional blocks specifically designed to ease implementation of highperformance digital OpenCable™ settop boxes. The MT2011 is a dual-conversion tuner design which requires no external tracking filters. This eliminates the need for manual alignments and simplifies its deployment on the production line where consistent high quality and reliability are key factors. The device maintains its controlled impedance across the entire input spectrum and exhibits good selectivity and sensitivity and low in-band emissions. Its low phase noise makes it an excellent choice for digital set top box applications. The high level of circuit block integration in the MT2011 reduces the number of external components required for a fully functional design, thereby lowering the overall solution cost. It includes a low noise amplifier (LNA) in the front, a Forward Data Channel (FDC) amplifier and an intermediate frequency (IF) buffer amplifier at the back-end. An on-chip System Reference Oscillator (SRO) output with selectable sub-multiples of 1, 2, or 4 can drive an additional tuner or IC in a multi-tuner application. A high first IF followed by an imagereject mixer gives the MT2011 unparalleled performance over its entire operating range from 48 MHz to 1 GHz. All functions of the MT2011 are controlled over a two-wire serial bus. This includes the ability to readback the status registers of the tuner as well as the on-board die temperature sensor.
