Description
The FCI FC8050Q chip is a highly integrated device for Terrestrial Digital Multimedia Broadcasting (T-DMB). FC8050Q has all of the performance needed to enable the full range of T-DMB applications. It consists of two main blocks, the RF tuner and channel decoder.
The 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 the RF block, additional components such as a bulky IF SAW filter and other IF matching components are no longer required. For the direct-conversion, it has a low noise fractional-N type frequency synthesizer and VCO. The RF block contains a Low Noise Amplifier (LNA), down-conversion mixer, Channel Selection Filter (CSF), and LO distribution network for Band-III.
The baseband block (BB) is an integrated circuit that provides a 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 a 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 an MPEG I/II Layer II (MUSICAM) algorithm. It provides HPI, EBI2 LCD Interface of Qualcomm QSC series modem chip, SPI and I2C as a HOST interface. When it is used, I2C is the host interface, serial TS interface is also supported.
