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) and operates

in the extended industrial temperature range of −40°C to +85°C.
