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.
