CXA3095N
24 pin SSOP (Plastic)
E95Y07-ST
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.
