PE97042 Datasheet, PDF (1/11 Pages) Peregrine Semiconductor – 3.5 GHz UltraCMOS Integer-N PLL Rad Hard for Space Applications

Product Description
Peregrine’s PE97042 is a high-performance integer-N PLL
capable of frequency synthesis up to 3.5 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 PLLs.
The PE97042 features a ÷10/11 dual modulus prescaler,
counters, and a phase comparator as shown in Figure 1.
Counter values are programmable through a serial or direct
hardwired mode.
The PE97042 is optimized for commercial space
applications. Single Event Latch up (SEL) is physically
impossible and Single Event Upset (SEU) is better than 10^-9
errors per bit / day. It is manufactured on Peregrine’s
UltraCMOS™ process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate, offering
excellent RF performance and intrinsic radiation tolerance.
