DPS7000 Hi-IQ TM Cable Modem VLSI RF Tuner IC OVERVIEW FEATURES The DPS7000 is a highly integrated, high-performance, very low-power RF Receiver/Tuner IC capable of receiving input signals between 48 MHz-1 GHz over a wide dynamic range and providing IF out to baseband PHY demodulators. • VLSI RF Cable Tuner IC This VLSI product integrates all the essential elements of the down conversion receiver: LNA, AGCs, Mixers, PLLs, IF Amplifier and varacters, thereby requiring minimal external components and no manual tuning. Only one external SAW filter is required. • 7 dB Noise Figure • Single 3.3 V supply operation • Very low operating power: 600 mW • 0-70°C operation The unique and proprietary architecture eliminates the need for tracking filters. The LNA provides a low Noise Figure and better than 6 dB return loss across the entire input frequency range. The integrated PLLs and VCOs provide fast lock and superior phase noise characteristics (better than 80 dBc/Hz at 10 KHz offset). The DPS7000 supports both DOCSIS and DAVIC standards and provides selectable 36/44 MHz IF out for the selected 6 or 8 MHz channels. • Fast channel select and lock • Very small form factor solution: 64 QFP • Integrates: - LNA - Gain control (RF and IF) - Wide dynamic range - Programmable dual synthesizers - Mixers - On-chip oscillator tuning elements - Serial port control • Minimal external components: - No manual tuning - No varactor - No other power supplies - Only one external SAW filter - No IF amplifier required VLSI Solution: Truly Minimal External Components The Communication Company TM DPS7000 Hi-IQ TM Cable Modem VLSI RF Tuner IC For more information please call: APPLICATIONS LSI Logic Corporation • DOCSIS/DAVIC Cable Modems North American Headquarters • Voice Over IP Telephony Milpitas, CA • MMDS Receivers Tel: 800 574 4286 • Cable TV, STB and DTV - call LSI Logic LSI Logic Europe Ltd.
