MT1393ETC FM/RDS
TUNER MODULE
PRODUCT BRIEF
The MT1393ETC is a highly integrated
FM tuner module with an on-board
data decoder for RDS (Europe) as well
as RBDS (US).

MT1393ETC FM/RDS Tuner Module
RF SILICON AND SUBSYSTEMS SOLUTIONS
FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS
Module is specifically designed to
meet the demanding performance
targets of automotive customers, at an
attractive price. This tuner module has
been developed for both FM audio
reception as well as RDS/RBDS data
reception and includes both an
integrated receiving condition
analyzer and an integrated RDS/RBDS
decoder. The high level of functionality
makes this tuner module an ideal
solution for use as a dedicated
background tuner enabling data
services offered via RDS/RBDS and
monitoring alternate frequencies. Its
excellent sensitivity and strong signal
performance produce clear audio and
reliable data reception, even under
critical receiving situations.
hardened to operate over an extended
temperature range and under adverse
climatic conditions and offers a very
small form factor for space-critical
applications. The tuner section of the
module contains a double down-
conversion system with a selective
pre-filter circuit and image reject
mixers. The dynamic selectivity
function evaluates the current
receiving situation continuously and
automatically determines the optimum
IF bandwidth. The audio path provides
an MPX signal output for external
stereo decoding.
MT1393ETC contains, in addition to
the demodulator and decoder, data
processing functions including
synchronization and error correction.
An integrated RAM buffer for up to 24
RBS/RBDS blocks decreases the
number of data pulls via the I2C bus.
This serial bus is used to control
frequency settings and multiple
programmable functions of the
MT1393ETC.
