FC8080 Terrestrial Digital Multimedia Broadcast RF tuner & Demodulator 1. Overview 1.1. Introduction 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.
FC8080 Terrestrial Digital Multimedia Broadcast RF tuner & Demodulator 1.2. Features Highly integrated digital device for DAB receiver (Eureka 147) Korea DAB/DMB (TTAS.KO -07.0024 and TTAS.KO-07.0026) standard compliant DAB OFDM channel demodulator and decoder Fully integrated, supports all DAB functions and modes (I, II, III and IV) Automatic Mode Detection (AMD) Full data rate of 1.

FC8080 Terrestrial Digital Multimedia Broadcast RF tuner & Demodulator 1.3. Block Diagram Figure 1. FC8080 Block Diagram 1.4. RF Tuner RF tuner has a direct-conversion structure that converts Band-3 signal around DC frequency. RF AGC and MIX AGC are controlled by the on-chip demodulator, and they regulate signal level to a proper value for the internal tuner blocks. The on-chip demodulator controls the gain of the PGA (Programmable Gain Amplifier), and PGA supply uniform signal to ADC as a result.
FC8080 Terrestrial Digital Multimedia Broadcast RF tuner & Demodulator 1.5. Functional Description 1.5.1. Frame Synchronization and Mode Detection Frame synchronization could get the start position of a frame and transmission mode by calculating the energy range of the sampling data. 1.5.2. Automatic Gain Control (AGC) AGC should preserve the amplitude of received signal to uniformity automatically. It is affected to control the level of Viterbi soft decision signal. 1.5.3.
FC8080 Terrestrial Digital Multimedia Broadcast RF tuner & Demodulator should detect sync byte of 204 bytes RS frame. 1.5.8. RS Decoder RS decoder should adapt (204, 188) shorten RS specification. It is capable of 8 byte error correction of 204 bytes. 1.5.9. Clock Generator The DMB Baseband Chip operates using internal clocks generated from various external clock source like as 16.384/19.2/24/24.576/27/27.12/38.4MHz oscillator. ⓒCopyright 2013 FCI (All Rights Reserved) Product datasheet 10/52 Rev.0.
