PRODUCT SPECIFICATION
PE3336
3.0 GHz Integer-N PLL for Low
Phase Noise Applications
Features
3.0 GHz operation
10/11 dual modulus prescaler
Internal phase detector
Serial, parallel or hardwired
programmable
Pin compatible with PE3236
Available in 44-lead PLCC and
miniature 48-lead MLP package
Ultra-low phase noise
Peregrine's PE3336 is a high performance integer-N PLL
capable of frequency synthesis up to 3.0 GHz. The
superior phase noise performance of the PE3336 makes
it ideal for applications such as LMDS / MMDS / WLL
basestations and demanding terrestrial systems.
The PE3336 features a 10/11 dual modulus prescaler,
counters and a phase comparator as shown in Figure 1.
Counter values are programmable through either a serial
or parallel interface and can also be directly hard wired.
The PE3336 is optimized for terrestrial applications.
Fabricated in Peregrine's patented UTSi (Ultra Thin
Silicon) CMOS technology, the PE3336 offers excellent
RF performance with the economy and integration of
conventional CMOS.

Electrostatic Discharge (ESD) Precautions
When handling this UTSi 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
rating specified in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UTSi CMOS
devices are immune to latch-up.
