Product Summary

The PE3291 is a dual fractional-N FlexiPowerTM phase-lock loop (PLL) IC designed for frequency synthesis. Each PLL includes a FlexiPowerTM prescaler, phase detector, charge pump and on-board fractional spur compensation. The PE3291 provides fractional-N division with power-of-two denominator values up to 32. The applications of it are CDMA handsets, CDMA base stations, Analog Cordless phones, One and two way pagers. The PE3291 Phase Locked-Loop is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.

Parametrics

PE3291 absolute maximum ratings: (1)Supply voltage: -0.3V to 4.0V ; (2)Voltage on any input:-0.3V to VDD+0.3V ; (3)DC into any input:-10mA to +10mA ; (4)DC into any output:-10mA to +10mA ; (5)Storage temperature range:-65℃ to 150℃.

Features

PE3291 features: (1)Ultra-Low Power via FlexiPower variable supply voltages ; (2)Modulo-32 fractional-N main counters ; (3)On-board fractional spur compensation: No tuning required, stable over temperature ; (4)Improved phase noise compared to integer-N architectures.
