FRONTEND 4049 FM5
3x8168; 3x8292
TARGET SPECIFICATION ELECTRICAL DATA
1. Description:
The frontend 4049 FM5 is specially designed for multimedia applications. It includes TV as well as
FM reception possibility. TV reception standard are B/G; I, D/K, L, L`. The frontend includes a
hyperband tuner which covers the frequency range from 45 to 865 MHz and an IF-part with SAW-
filter, IF-amplifier, video- and sound demodulator. So the AF signal is available at the audio output
terminal, the CVBS signal is available at the video output terminal. Also a 2nd IF output is provided,
which allows external sound demodulation for stereo and NICAM reception. A video buffer is built
in which makes a direct connection to 75 inputs possible. The reception frequency range is
divided in VHF low, VHF high and UHF.
VHFlow part of the tuner is used for FM reception also. Complete FM signal processing including
demodulation and stereo decoding is built in. Baseband signals L (left) and R (right) as well as
MPX (Baseband Multiplex signal) are on pins available.
Band, standard selection and tuning are done via I²C-bus, completely. Also a digital AFC-function
can be realized, because the AFC-voltage generated by the IF-demodulator is fed to an
analogue/digital converter which is integrated in the IF demodulator-IC and readable via I²C-bus.
A DC/DC converter is built in. Therefore supply voltage is 5V only.
