Product Specification
PE3512
Product Description
The PE3512 is a high-performance static
UltraCMOS™
prescaler with a fixed divide ratio of 4. Its operating frequency
range is DC to 1500 MHz. The PE3512 operates on a nominal
3 V supply and draws only 8 mA. The input and output
interfaces support both AC-coupled, low-Z RF as well as direct
connection to low voltage positive logic devices. It is packaged
in a small 6-lead SC-70 and is ideal for frequency scaling
solutions
The PE3512 is manufactured in Peregrine’s patented Ultra
Thin Silicon (UTSi©) CMOS process, offering the performance
of GaAs with the economy and integration of conventional
CMOS.
