Peregrine’s PE97042 is a high-performance integer-N PLL
capable of frequency synthesis up to 3500 MHz. 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
interface, and can also be directly hard wired.
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.
