GENERAL DESCRIPTION

The ADA4303-2 is a 75 Ω, two-output active splitter for use

in applications where a lossless signal split is required. Typical

applications include multituner digital set-top boxes, cable

splitter modules, multituner/digital cable ready (DCR)

televisions, and home gateways where traditional solutions

require discrete passive splitter modules with separate fixed

gain amplifiers.

The ADA4303-2 is a low cost alternative that simplifies designs

and improves system performance by integrating a signal

splitter element and a gain block into a single IC. The ADA4303-2

is available in a 12-lead chip scale package (LFCSP_VQ) and

operates in the extended industrial temperature range of −40°C

to +85°C.
