Product Specification
PE3335
Product Description
Peregrine’s PE3335 is a high performance integer-N PLL
capable of frequency synthesis up to 3000 MHz. The
superior phase noise performance of the PE3335 makes it
ideal for applications such as LMDS / MMDS / WLL
basestations and demanding terrestrial systems.
The PE3335 features a 10/11 dual modulus prescaler,
counters, phase comparator and a charge pump as shown
in Figure 1. Counter values are programmable through
either a serial or parallel interface and can also be directly
hard wired.
The PE3335 Phase Locked-Loop is optimized for terrestrial
applications. It 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.

Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS™ device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the specified rating in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
