Reception Analog Signal Processor IC for Infrared Space Digital Audio Communication
Description
The CXA3668N is an IC that performs reception side
analog signal processing for optical communication
in combination with an infrared photodiode within a
Digital Infrared Audio Transmission (DIAT) system.
This IC incorporates a low noise trans-conductance
amplifier (I/V amplifier) that converts the optical
current from the photodiode into a voltage and
amplifies it, an AGC amplifier, a low-pass filter, band-
pass filters, and an output amplifier.
The band-pass filters are used to separate the
desired signal and the interfering signal. This chip
has the two types of Full (3 to 6MHz) and Half (3 to
4.5MHz) band-pass filters, and these can be
switched according to the application.
Full: Full-band width (3 to 6MHz)
Half: Half-band width (3 to 4.5MHz)
Features
Wide dynamic range
On-chip I/V amplifier
On-chip output filter
Filter band switching pin
Surface mounting package (24-pin SSOP)
