CXA3556N
IF Down Converter for Digital Broadcast
Description
The CXA3556N is a one-chip integrated IC that
processes IF signals of a digital broadcast tuner and
includes an AGC amplifier circuit, a mixer circuit, a
local oscillator circuit and an output amplifier circuit.
The package utilizes a 24-pin SSOP suitable for
surface mounting.
