BCM3416

ADVANCED DIGITAL CABLE TUNER

Tuner Application Example (Cable Modem)

Supports 64 and 256 QAM

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

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

* = For use only in applications where the input frequency to the
diplexer is less than 1000 MHz.

Narrowband first IF eliminates processing of unnecessary
channels

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

Lower BOM cost
