描述 Description

The FCI FC8080 chip is a highly integrated device for terrestrial digital multimedia Broadcasting. FC8080 has all of the performance needed to enable the full range of T-DMB application. It consists of two main blocks, RF tuner and channel decoder.
RF block supports single-band (Band-III). It is a highly integrated component working with a single 1.2V power supply. Because direct-conversion architecture is used in RF block, additional components such as bulky IF SAW filter and other IF matching components are no longer required. For the direct-conversion, it has low noise fractional-N type frequency synthesizer and VCO. RF block contains LNA, down-conversion mixer, channel selection filter (CSF), and LO distribution network for Band-3.
Baseband block is a integrated circuit provides channel decoder for Digital Multimedia Broadcasting(DMB) signals based on ETS 300 401 (EUREKA-147). It is also in compliance with the function of Korea DAB/DMB (TTAS.KO -07.0024 and TTAS.KO-07.0026) standard. It contains 10-bit Analog to Digital Converter (ADC) for IF input, OFDM demodulator, Reed Solomon decoder and convolutional de-interleaver for providing forward error correcting. For Audio data, It uses MPEG I/II Layer II (MUSICAM) algorithm. It provides EBI2 LCD Interface of Qualcomm QSC series modem chip, SPI and I2C as a HOST interface. When it is used I2C as host interface, serial TS interface is supported for data transmission also.
