PE97240
Description
Peregrine’s PE97240 is a radiation tolerant highperformance Integer-N PLL capable of frequency synthesis up to 5 GHz. The device is designed for mercial space applications and optimized for superior phase noise performance.
The PE97240 features a selectable prescaler modulus of 5/6 or 10/11, counters and a phase parator as shown in Figure 1. Counter values are programmable through either a serial interface or directly hard-wired.
The PE97240 is available in a 44-lead CQFP and is manufactured on Peregrine’s Ultra CMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering excellent RF performance and intrinsic radiation tolerance.
