MxL608
Low Cost Digital Cable and Terrestrial
Silicon Tuner Product Brief
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 MaxLinear's 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 75 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 blind-
scan 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.
