Characterized by high input sensitivity and low phase noise, these devices are specially designed for use in high-frequency phased-locked loop (PLL PLL - phase-locked loop ) oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air and signal-path down conversion circuits. Inphi's new prescalers deliver unsurpassed performance in a small form factor package for equipment manufacturers seeking a reliable and affordable solution for a broad array of commercial, military, and government systems. Until recently, prescalers above 14 GHz were not commercially available, which presented serious limitations for advanced synthesizers at higher frequencies. Inphi's line of DC to 25 GHz prescalers, announced in May in die form and land grid array The land grid array (LGA) is a type of surface-mount packaging used for integrated circuits. It can be electrically connected to a PCB either by the use of a socket or by soldering directly to the PCB. (LGA LGA abbr. large for gestational age LGA Large for gestational age, see there ) ceramic packages, enabled design engineers to phase lock a high-frequency oscillator to a low-frequency reference source by means of a prescaler and a commercial off-the-shelf Commercial off-the-shelf (COTS) is a term for software or hardware, generally technology or computer products, that are ready-made and available for sale, lease, or license to the general public. digital PLL circuit for the first time. This new approach reduced the total part count and eliminated the labor-intensive tuning process associated with analog circuits. Through the introduction of these high-frequency prescalers in low-cost QFN plastic packages, Inphi now extends this competitive advantage to high-volume commercial applications such as point-to-point microwave radios, yttrium iron garnet Yttrium iron garnet (YIG) is a kind of synthetic garnet, with chemical composition Y3Fe2(FeO4)3, or Y3Fe5O12. It is a ferrimagnetic material with Curie temperature 550 K. (YIG YIG Yttrium-Iron-Garnet (bandwidth filter) YIG Youth in Government ) phase-locked oscillators, and advanced synthesizers that require low-cost surface-mount components. Inphi's DC to 25 GHz prescaler circuits, listed in Table 1, perform divide-by-2, divide-by-4, or divide-by-8 functions in a variety of microwave and communications systems. Available in positive 3.3 V power supply version, these prescalers exhibit high input power sensitivity (see Figure 1), low added phase noise, and low DC power consumption across a wide frequency range.

Inphi's prescalers are currently sampling to OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and customers worldwide. These products are offered in a 3 x 3 mm2 QFN plastic package, in a 7 x 7 mm2 LGA ceramic package, or in die form. The packaged parts are also available on an evaluation board with SMA connectors for testing purposes. Unit pricing for all three prescalers in the QFN plastic package is $22 for production quantities of 5,000 units.
