Product Description
Peregrine’s PE3340 is a high performance integer-N PLL
capable of frequency synthesis up to 3.0 GHz. The
superior phase noise performance of the PE3340 makes
it ideal for applications such as wireless local loop
basestations, LMDS systems and other demanding
terrestrial systems.
The PE3340 features a 10/11 dual modulus prescaler,
counters and a phase comparator as shown in Figure 1.
Counter values are programmable through a three wire
serial interface.
Fabricated in Peregrine’s patented UTSi® (Ultra Thin
Silicon) CMOS technology, the PE3340 offers excellent
RF performance with the economy and integration of
conventional CMOS.

PE3340
Advance Information
Functional Description
The PE3340 consists of a prescaler, counters, a
phase detector and control logic. The dual modulus
prescaler divides the VCO frequency by either 10 or
11, depending on the value of the modulus select.
Counters “R” and “M” divide the reference and
prescaler output, respectively, by integer values
stored in a 20-bit register. An additional counter
(“A”) is used in the modulus select logic.
Figure 3. Functional Block Diagram
The phase-frequency detector generates up and
down frequency control signals. Data is written into
the internal registers via the three wire serial bus.
There are also various operational and test modes
and a lock detect output.
