PE9701

www.DataSheet4U.com Product Specification PE9701 Product Description Peregrine’s PE9701 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 PLLs. The PE9701 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 PE9701 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-oninsulator (SOI) technology on a sapphire substrate, offering excellent RF performance and intrinsic radiation tolerance.
