PE3341 Datasheet | pSemi

Product Specification Product Description The PE3341 is a high performance integer-N PLL with embedded EEPROM capable of frequency synthesis up to 2700 MHz with a speed-grade option to 3000 MHz. The EEPROM allows designers to permanently store control bits, allowing easy configuration of self-starting synthesizers. The superior phase noise performance of the PE3341 is ideal for applications such as sonet, wireless base stations, fixed wireless, and RF instrumentation systems. The PE3341 Features a ÷10/11 dual modulus prescaler, counters, a phase parator, and a charge pump as shown in Figure 1. Counter values are programmable through a threewire serial interface. The PE3341 Ultra CMOS™ Phase Locked-Loop is manufactured in Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS process, offering excellent RF performance with the economy and integration of conventional CMOS. 2700 MHz Integer-N PLL with Field-Programmable EEPROM Features - Field-programmable EEPROM for self- starting applications - Standard 2700 MHz operation, 3000 MHz speed-grade option - ÷10/11 dual modulus prescaler - Internal charge pump - Serial programmable - Low power - 20 m A at 3 V - Ultra-low phase noise - Available in 24-lead TSSOP or 20-lead 4x4 mm QFN package Figure 1.
