Die Form
Peregrine’s PE3337 is a high-performance integer-N PLL
capable of frequency synthesis up to 3.0 GHz. The
device is designed for superior phase noise performance
while providing an order of magnitude reduction in
current consumption, when compared with existing
commercial space PLL’s. The device is offered in
electrically screened die form for MCM/Hybrid
applications.
The PE3337 features a ÷10/11 dual modulus prescaler,
counters, and a phase comparator as shown in Figure 1.
Counter values are programmable through a serial
interface, and can also be directly hard wired.
Fabricated in Peregrine’s patented UTSi (Ultra Thin
Silicon) CMOS technology, the PE3337 offers excellent
RF performance and intrinsic radiation tolerance.
