FC8400
Advanced Terrestrial Digital Multimedia Broadcast
RF tuner & Demodulator
1. Overview
1.1. Introduction
The FCI FC8400 chip is a highly integrated device for AT-DMB (Advanced Terrestrial Digital
Multimedia Broadcasting). FC8400 has all of the performance needed to enable the full range
of AT-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 AT-DMB (Advanced
Terrestrial Digital Multimedia Broadcasting) signals based on ETS 300 401 (EUREKA-147). It is
also in compliance with the function of Korean DAB/DMM/AT-DMB (TTAS.KO -07.0024 and
TTAS.KO-07.0026 and TTAK.KO-07-0070) 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, 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 also.
