Description

The CXA3025N is a single chip TV tuner IC which

performs as a mixer, oscillator for UHF and VHF-

CATV bands. An IF amplifier is also provided.

This IC adopts a 24-pin SSOP package (0.8mm

pitch) in response to the trend towards miniaturizing

the tuner and automatic IC mounting.

Features

• Low noise figure

• Superior cross modulation
