ADVANCED DIGITAL 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

Supports 64 and 256 QAM

Narrowband first IF eliminates processing of unnecessary

channels

•

Input frequency range of 50 MHz through 860 MHz *

IF output range of 36 MHz through 44 MHz

High linearity across entire frequency range

Differential signals for high noise immunity

Eliminates need for image reject mixer

DOCSIS and EuroDOCSIS 1.0/1.1/2.0 compliant

Minimal in-house RF expertise required

Superior alternative to can tuners

•

High quality and reliability (no hand tweaking)

Enables lower profile and smaller designs

Simplified manufacturing flow

Highly integrated and cost-effective

•

Minimal BOM with reference designs available

IF AGC and frequency synthesizers included

Standard logic CMOS with single 3.3V supply

48-pin TQFP

Lower BOM cost

Applications

•

Cable modems

Cable set-top boxes
