1 / 14 page 3X8168 ED Page: 1/14 November 02 8168ED01.DOC 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 2 nd 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 Ω 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. 2. Mechanical Characteristics: 2.1. Dimensions: according drawing 3x8168GZ 2.2. Weight: appr. 52 g I²C bus signal SCL I²C bus signal SDA Address selection for I²C bus FM sound output R FM sound output L 2nd IF Video output CVBS Supply voltage V S1 AF sound output / FM MPX |
