FC8001
Terrestrial Digital Multimedia Broadcast
RF tuner & Demodulator
1. Overview
1.1. Introduction
The FCI FC8000 chip is a highly integrated device for terrestrial digital multimedia
Broadcasting. FC8000 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 double-band (Band-3/L-Band). 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 each band such as Band-3, and L-Band.
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 HPI, SPI and I2C as a
HOST interface.
