Prescalers PE35110 pages

Product Specification

PE3511
1500 MHz Low Power UltraCMOS™
Divide-by-2 Prescaler

Product Description
The PE3511 is a high-performance static UltraCMOS™
prescaler with a fixed divide ratio of 2. Its operating frequency
range is DC to 1500 MHz. The PE3511 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 PE3511 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.

Note 1:

CMOS logic levels can be used to drive the reference input if DC coupled. Voltage input needs to be a minimum of 0.5 Vp-p. The
input edge rate should be faster than 80mV/ns from DC - 10 MHz.
