New PLLs for Commercial Space Applications Offer Improved Phase Noise, One-tenth the Power of Competitive Parts; Core of Two New Device Families Also Available For Custom Chip Development.Business/Government/Aerospace Editors SAN DIEGO--(BUSINESS WIRE)--Feb. 28, 2000 Peregrine Semiconductor Corp. today introduced the first products in two new families of high-performance phase-locked loop A phase-locked loop or phase lock loop (PLL) is an electronic control system that generates a signal that has a fixed relation to the phase of a "reference" signal. A phase-locked loop circuit responds to both the frequency and the phase of the input signals, automatically (PLL PLL - phase-locked loop ) devices that provide precise frequency synthesis capabilities for commercial satellite communications. The PE9600 and PE9700 PLL family devices feature greater than 10 dB in phase noise improvement and one-tenth the power consumption of competitive devices, making them ideal replacements in existing designs and the clear first choice in new designs. Peregrine also announced that the PLL circuit core used in the new devices is available as a building block for customer-defined devices. The PE9600 devices operate at up to 2.2 GHz and are combined with an external prescaler to generate the LO (local oscillator Noun 1. local oscillator - an oscillator whose output heterodynes with the incoming radio signal to produce sum and difference tones heterodyne oscillator ) signals required by satellite communications transceivers. The prescaler typically divides the required LO signal frequency down to 1.4 GHz, placing it within the operating frequency of the PE9600 low-phase-noise PLL. The PE9700 devices operate at up to 3.0 GHz, and are intended for newer designs, eliminating the external prescalar function and reducing the parts count and cost of a frequency synthesizer A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie-talkies, CB radios, satellite board. The PE9600/PE9700 chips are fabricated in Peregrine's patented UTSi(R) (Ultra-Thin Silicon) CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. process technology, which utilizes a synthetic sapphire substrate that is a pure insulator, rather than semiconductor. As a result, they provide excellent RF performance, and easily surpass the rad-hard (radiation-hardened) requirements for reliable operation in commercial satellites. The PLLs are immune to single-event latch-up (SEL (SELect) A toggle switch on a printer that takes the printer alternately between online and offline. 1. SEL - Self-Extensible Language. 2. SEL - Subset-Equational Language. ), have single-event upset (SEU SEU Shoot 'Em Up (game category) SEU St. Edward's University (Austin, Texas) SEU Southeast University SEU Single Event Upset ) of less than 10(-9) errors per bit/day, and offer total-dose radiation tolerance of 100 krad. Initially, each of the new product families contains two ICs. The PE9601 and PE9602 operate at 2.2 GHz, and the PE9701 and PE9702 operate at 3.0 GHz. All of the devices feature a 10/11 dual-modulus prescaler, counters and a phase comparator comparator Instrument for comparing something with a similar thing or with a standard measure, in particular to measure small displacements in mechanical devices. In astronomy, the blink comparator is used to examine photographic plates for signs of moving bodies. . The counters are programmable through either a serial or parallel interface, and can also be directly hard-wired. Two of the PLLs, the PE9601 and PE9701, have an on-chip charge pump, while the PE9602 and PE9702 have an up/down output to drive an external charge pump. Performance Specifics The Peregrine PLLs exhibit industry-leading performance for commercial space applications. Phase noise and power consumption at various comparison frequencies, and under both temperature and radiation extremes, are unmatched by any comparably priced devices. At a 1 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. comparison frequency, with an ambient temperature of from -40 degrees C to 85 degrees C, PE9600/PE9700 devices have a -159 dBc/Hz phase noise floor, which is 10 dBc/Hz lower than the best-performing competitive chips. Power consumption of the PE9600 is 60 mW, and of the PE9700 is 75 mW, compared to the 625 mW consumed by the leading competitive parts. After exposure to 100 krads of radiation, phase noise performance of the Peregrine PLLs changes by less than 1 dBc/Hz, and there is no change in power consumption. Packaging, Price and Availability The PE9600/PE9700 PLLs are offered in a 44-pin CQFJ CQFJ Ceramic Quad Flat Pack J-Leaded (ceramic quad-flat-pack, J-lead) package at a price of $2500 each in quantities of 100 for fully flight-screened devices. Sample quantities are available now, with volume production planned for early in the third quarter. About Peregrine Semiconductor Headquartered in San Diego, California “San Diego” redirects here.
