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.
