Product Description Peregrine’s TDPL97240 is a radiation tolerant high-performance, Integer-N PLL capable of frequency synthesis up to 5 GHz. The device is designed for commercial space applications and optimized for superior phase noise performance. The TDPL97240 features a selectable prescaler modulus of 5/6 or 10/11, counters and a phase comparator as shown in Figure 1. Counter values are programmable through either a serial interface or directly hard-wired. The TDPL97240 is available in a ceramic 7 x 7 mm, 48-lead CQFN and is manufactured on the UltraCMOS® process, a patented variation of silicon-on- insulator (SOI) technology on a sapphire substrate, offering excellent RF performance and intrinsic radiation tolerance.
