1390 FM RDS Tuner Module
The 1390 FM RDS Tuner Module
is a high-end product designed
to meet the demanding
performance, market, and
pricing targets of automotive
customers.
This tuner module is specifically
designed to be used as an FM
audio tuner and/or RDS data
tuner. Its special background
tuner technology minimizes
interference with the main tuner
and supports high-end double
tuner systems. Its excellent
sensitivity and large signal
performance produces clear
sound and reliable RDS data
even in weak receiving
situations. Additionally, the tuner
module is environmentally
hardened to operate under an
extended temperature range and
adverse climatic conditions.
The FM section contains a single
down-conversion system with a
selective prefilter circuit and
state-of-the-art three-stage
ceramic IF filtering. Using
appropriate external signal

processing, the stereo audio
signal can be derived from the
MPX signal. The integrated RDS
demodulator provides a serial
clock and data output. Decoding
this data with an external
microprocessor enables use of
the RDS for numerous
applications, including
alternative frequencies and traffic
messaging channels. Monitoring
the RDS quality output provides
a simple method of evaluating
the current block error rate.
Analog outputs for field strength
and multipath allow optimization
of tuner performance. The
sensitivity of the seek stop mode
can be adjusted via I
2
C bus.
The 1390 FM RDS Tuner Module
provides two software-controlled
switching outputs (open drain).
Frequency setting and multiple
tuner functions are controlled via
I
2
C serial bus. This control is
intended to be handled by an
external microprocessor.
