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:

Applications

■

Digital terrestrial and cable STBs

Integrated Digital Televisions (iDTVs)

Tuner modules

Portable TVs and media players

Blu-Ray recorders

Multi-tuner Personal Video Recorder (PVRs)

■

DVB-T/T2

ISDB-T

J.83 Annex A/B/C

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.

Benefits

■

Single hardware design for all global digital

terrestrial applications

Ultra low power, 350mW (Active), or 110mW

(Standby)

Simple two-layer PCB design

No external Surface Acoustic Wave (SAW) filters

Low BOM cost
