Device: MSP3410D.
Features: Integrated A/D converter for sound-IF inputs
Automatic Gain Control (AGC) for analog IF input
FM demodulation
1) Description
The MSP 3410D is designed to perform demodulation of FM or AM-Mono TV sound.
Alternatively, two-carrier FM systems according to the German or Korean terrestrial specs or
the satellite specs can be processed with the MSP 3410D.
Digital demodulation and decoding of NICAM-coded TV stereo sound, is done only by the MSP
3410.
The MSP 3410D offers a powerful feature to calculate the carrier field strength which can be
used for automatic standard detection (terrestrial) and search algorithms (satellite). The IC may
be used in TV sets, as well as in satellite tuners and video recorders. It offers profitable
multistandard capability, including the following advantages.
Fabricated in an advanced CMOS process, the MSP3410D is provided in a space-saving
80-lead PQFP surface-mount plastic package.
