CXA3095N
All Band TV Tuner IC (VHF-CATV-UHF)
Description
The CXA3095N is a single chip TV tuner IC which
performs as an oscillator, mixer for VHF-CATV and
UHF bands. An IF amplifier is also provided.
This IC adopts a 24-pin SSOP package (0.8mm
pitch) in response to the trend toward miniaturizing
the tuner and automatic IC mounting.
This IC is the inverted product of the CXA3025N
pin assignment.
