Peregrine Semiconductor PE334x Integer-N PLLs Embed EEPROM; Permanent Store of Control Bits Allows Easy Configuration
SAN DIEGO --(Business Wire)-- June 24, 2004 -- Peregrine Semiconductor Corporation, a leading supplier of high-performance RF CMOS and mixed-signal communications ICs, today broadened its high-performance integer-N phased locked-loop (PLL) family with the introduction of the PE3341 and PE3342 devices. The new PLLs feature embedded field-programmable EEPROM capable of frequency synthesis up to 2.7 GHz, with a speed-grade option to 3.0 GHz. The EEPROM allows designers to permanently store control bits, allowing easy configuration of self-starting synthesizers.
The PE334x devices, operating with 20 mA at 3V, include a /10/11 dual modulus prescaler, counters, and a phase comparator. The counter chain operates in high-frequency or prescaler bypass mode. Counter values are programmable through a three-wire serial interface. The PE3341 features a complete charge pump, while the PE3342 utilizes phase-frequency detector (PD) outputs, making it easier to scale to higher tuning voltages. The PD outputs generate up and down frequency control signals and are also used to enable a lock detect circuit.
"UTSi(R) RF CMOS Silicon-on-Sapphire technology enables the unique ability to monolithically integrate EEPROM with our standard PLL core," said Rodd Novak, director of marketing and business development. "This feature effectively eliminates a microcontroller from our customers' bill of materials, simplifies design, and lowers total cost," he added.
The PE3341 and PE3342 devices are available in 24-lead TSSOP or 20-lead 4x4mm QFN package and are the newest members of Peregrine's extensive PLL family. Peregrine also offers space-qualified PLLs with embedded EEPROM as the PE9721 and PE9722 devices in a 24-lead CFPG package. Product samples, unit pricing, and volume production are available now through Peregrine Semiconductor and its worldwide distribution partner, Richardson Electronics.
About UTSi(R) RF CMOS Silicon-On-Sapphire (SOS) Technology
UTSi(R) (Ultra-Thin-Silicon) RF CMOS is a proprietary, patented variation of silicon-on-insulator (SOI) technology. It is the first commercially qualified use of sapphire substrates with high yields and competitive costs. Significant performance advantages exist over competing mixed-signal processes such as GaAs, SiGe BiCMOS, and bulk silicon CMOS in applications where RF performance, low power, and integration are paramount.
