| Popis: | A dual-band digital TV tuner for CMMB application SoC is presented. The single-chip SoC satisfies all requirements of CMMB application with margin. Moreover, the SoC meets the GSM IOP which means the co-operation GSM transmitter and mobile TV reception. To suppress GSM transmitter signal in UHF band, LC-tuned load and tunable input matching scheme are adopted in UHF LNA. The SoC consists of two RF LNAs covering the 470 to 798MHz (UHF), and 2635 to 2660MHz (S-BAND) bands, an analog baseband filter supporting low pass filtering for direct conversion, and ΔΣ fractional-N synthesizer with one VCO. The measured sensitivity at UHF for the QPSK mode is −9.8dBm with ADC clock shift scheme. |
