MT1467 AM/FM DOUBLE

TUNER MODULE

PRODUCT BRIEF

The MT1467 tuner modules are designed

for high-end automobile radios and

entertainment system.

MT1467 Tuner Module

Module is designed specifically for

high-end automotive radio and

entertainment systems. It is optimized

to meet the performance, market and

pricing demands of automotive

customers.

minimize dropouts due to multipath

interference, the MT1467 module

incorporates one AM tuner and two

independent FM tuner sections to

support a high-performance phase

diversity function. The 10.7 MHz IF

output can interface readily with a

dedicated DSP (e.g. Philips SAF

7730) to form a DSP-based digital

AM/FM radio system.

same frequency in “phase diversity”

mode, the FM tuners can also be

set to different frequencies to

receive a RDS channel in the

background while listening to

another station. An AF sample-and-

hold interface for the external DSP

enables inaudible checking of

alternative frequencies within the

RDS network.

AGC with a closed loop control and

adjustable thresholds. A keyed AGC

function is implemented to prevent

receiver desensitization due to

erroneous AGC response. The IF

AGC is controlled by the external

DSP. Furthermore the module

features automatic alignment for the

tracking filters and the image rejection

filters. All tuner functions and

parameters can be controlled via a

serial bus interface.

optional. Versions for special AM

(LW/MW/SW) and FM bands

(Europe, USA, Japan) are also

available. The MT1467 module is

designed specifically for typical

automotive operating conditions. It

fully complies with RoHS

requirements.

While both FM tuners receive the
