MT1501 EDC DAB TUNER
MODULE
PRODUCT BRIEF
The MT1501 tuner module is designed for
terrestrial digital audio broadcasting
(DAB) in high-end automobile radios and
entertainment system.
MT1501 Tuner Module
RF SILICON AND SUBSYSTEMS SOLUTIONS
FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS
The MT1501 EDC DAB Tuner
Module is designed for VHF Band
III and L-Band reception
according to the Eureka 147 DAB
standard. It has been optimized to
meet the specific requirements for
mobile applications and to provide
superior performance under
extreme environmental conditions
(-40 to +85 °C).
The MT1501 module features a
down-conversion to a fixed IF
which can be demodulated by an
appropriate external channel
decoder. An internal closed-loop
AGC automatically controls the IF
output level. The threshold level
can be set by the serial bus.
The MT1501 module also
features digitally aligned tracking
filters for both bands as well as an
IF SAW filter in order to minimize
interferences and distortion
caused by undesired signals or
adjacent channels. The antenna
matching is also digitally aligned.
An integrated EEPROM is
provided to store these alignment
data.
By using the WAGC input pin
the external demodulator can
freeze the integrated AGC circuit
to keep the IF output level
unchanged during the null symbol
of the DAB signal. This prevents
the A/D converter from clipping as
the transmission resumes.
A 12V DC phantom power
supply can be routed from the pin
connector to the antenna input of
an active antenna system.
Moreover a level indicator circuit
provides a DC-voltage dependent
on the RF-input level.
The MT1501 module fully
complies with RoHS
requirements. Customized
mechanics and connectors are
available on request.
