CXA3025N
All Band TV Tuner IC (VHF-CATV-UHF)
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.
