Product Specification
PE3501
Product Description
The PE3501 is a high-performance dynamic UltraCMOS™
prescaler with a fixed divide ratio of 2. Its operating frequency
range is 400 MHz to 3.5 GHz. The PE3501 operates on a
nominal 3 V supply and draws only 12 mA. It is packaged in a
small 8-lead TSSOP and is ideal for frequency scaling and
microwave PLL synthesis solutions.
The PE3501 is manufactured on Peregrine’s UltraCMOS™
process, a patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering the performance
of GaAs with the economy and integration of conventional
CMOS.
