Peregrine Semiconductor Expands PLL Frequency Synthesizer Portfolio

(Product News, 4 Mar 2008)

Peregrine Semiconductor Corp. has launched the UltraCMOS PE97022 and PE97042 phase locked loop (PLL) frequency synthesizers that are rated at 3.5GHz. The new Integer-N PLLs boast an ultra-low normalized phase noise of -216dBc/Hz and feature programmable counters, a phase comparator and +10/11 Dual Modulus Prescaler, allowing for backward compatibility to previous generation PLLs.

The PE97042 offers direct or serial programming modes, while the PE97022 offers an additional parallel mode option. The devices are suitable for use in skew suppression, frequency synthesis for local oscillators, signal modulation and demodulation, clock recovery, jitter reduction, regeneration of signals and pulse synchronization of signals from mass storage devices.

The UltraCMOS silicon-on-sapphire based devices are fully space qualified and immune to Single Event Latch-up (SEL). A superior resistance to Single Event Upset (SEU) of less than 10-9 errors per bit-day and tolerance to total dose radiation of up to 100 Krads (Si) make these devices ideal for the demanding rigors of space applications. Further, because the PE97022 and PE97042 are manufactured on the UltraCMOS process, the devices utilize ultra-low power of approximately 45mA to meet system-level requirements.

Both devices are offered in the 44-pin CQFJ package, while the PE97042 is also available in die form. The PE97022 is a drop-in replacement for the PE9702, while upgrading from the PE9704 to the PE97042 requires only minimal design modification.
