Radiation Tolerant UltraCMOS® Delta-Sigma Modulated Fractional-N Frequency Synthesizer: PE97640
The PE97640 from Peregrine Semiconductor is a delta-sigma, modulated fractional-N synthesizer optimized for frequency synthesis up to 5 GHZ in commercial space applications. With a 5/6 or 10/11 dual modulus prescaler, counters, a delta sigma modulator, a phase comparator, and charge pump, the device is optimized for superior phase noise performance, radiation tolerance, and high frequency selectivity.
The PE97640 synthesizer features a phase noise floor figure of -225 dBc/Hz. It is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, and is available in a 64-lead QCFP package.
