ADVANCED LOW IF DIRECT CONVERSION CABLE TUNER

S U M M A R Y O F B E N E F I T S

F E A T U R E S

Single-chip direct conversion silicon tuner completes system

design with Broadcom cable modem

Extreme integration level leads to highly cost-effective BOM

Eliminates significant external components:

•

DOCSIS^®/EuroDOCSIS™ 1.0/1.1/2.0

•

SAW (Surface Acoustic Wave) IF filters

RSSI measurement components

IF amplifiers

Supports 64, 256, and 1024 QAM

Input frequency range of 50 MHz through 860 MHz

Oscillator components

IF (intermediate frequency) output range of 4 MHz, 4.5 MHz,

and 5 MHz

Package optimization enables low-cost 2-layer system PCB

Minimal in-house RF expertise required

•

For use in 6-MHz, 7-MHz, and 8-MHz systems

High linearity across entire frequency range

Differential signals for high noise immunity

Integrated and cost-effective BOM:

•

Support for DOCSIS/EuroDOCSIS 2.0 enables one device

solution to be used worldwide

Superior alternative to can tuners

•

High quality and reliability (no hand tweaking)

Enables lower profile and smaller designs

Proven reference design for quick time-to-market

Simplified manufacturing flow

•

True single-chip tuner

Single 3.3V supply voltage

Fully integrated oscillator

Fully integrated channel selectivity

Single supply voltage provides low-cost operation

Low-power consumption

•

Symmetrical IF output for direct connection to channel decoder

•

RSSI (Received Strength Signal Indicator) information

provided through I²C bus

A P P L I C A T I O N S

Standby mode

•

Cable Modems

•

40-pin MLF package

Cable Gateways

Voice Cable Modems

Tuner Application Example (Cable Modem)
