Introduction

The MxL608 is a high performance, low power digital terrestrial and cable television silicon tuner that is targeted at price-sensitive Set-Top Boxes (STBs). Based on market-proven 65nm digital CMOS technology, the MxL608 is software configurable for all global terrestrial and cable reception standards without the need for any hardware modifications. Supported standards include: The MxL608 converts a single-ended 75Ω RF input signal to an IF output frequency that is software programmable between 4MHz and 44MHz. All channel selection filters are fully integrated and software configurable for 6MHz, 7MHz, or 8MHz channel bandwidths. The MxL608 includes an accurate input power detector and channel scan algorithm that offers significant improvement in channel scan time, especially under blindscan conditions. Channel filtering, Low Noise Amplifier (LNA), and loop-through output are completely integrated. The external Bill Of Materials (BOM) is limited to a small number of standard value discrete components. The MxL608 has a typical power consumption of ~350mW in Digital Terrestrial mode. In Low Power Standby mode, the MxL608 consumes just 110mW, while still able to pass through the RF signal to an analog TV through the loop-through output. The MxL608 uses an API-based software architecture, which reduces the programming effort and eliminates the need for complicated register calls. The MxL608 is pin-compatible with the market-leading MxL603 tuner, which enables current customers to leverage their existing designs and achieve faster time-to-market with minimal engineering investment. A complete Reference Design Kit (RDK) is available for cable and terrestrial applications, including a reference PCB schematic and layout files, detailed BOM, hardware design guide, software programming guide, source code, and standard-specific performance test reports. The RDK supports a dual layout configuration, with or without an external balun, to enable manufacturers to trade-off cost vs sensitivity performance using the same hardware design.
