Haier digital satellite reception demodulation and channel decode chip (Hi3102)


    The Hi3102 is mainly used in digital satellite receiver, unitary digital television and digital satellite receiving PC card, and can also be used in satellite data communication compatible with the DVB-S standard.


     Products’characters:
 

•  Receive I-input and Q-input baseband analog signals which come from ZIF-Tuner
•  The sampling frequency of dual 6-bit ADCs in the chip can be as high as 100Msps
•  All-digital carrier recovery loop’s capture range is very wide, so it can correct the significant carrier frequency deviation which is caused by low cost LNB or low cost tuner
•  In-chip integrated FEC circuit is mainly composed of high-efficient Viterbi soft decision decoder and RS decoder. The viterbi soft decoder block can decode the convolutional code with rate 1/2, 2/3, 3/4, 5/6 and 7/8
•  It provides extensive locking indication and channel performance (signal intensity, signal-to-noise rate and error code rate etc.) monitoring, which can save debugging time and test implements
•  It supports fast channel automatic scan, which can increase test efficiency and save installation time
