DSC2011FE2-F0016

Crystal-less™ Configurable Clock Generator

General Description

The DSC2011FE2-F0016 is a programmable, high

performance dual LVCMOS output oscillator utilizing

Micrel's proven silicon MEMS technology to provide

excellent jitter and stability

while

incorporating

additional device functionality. Two LVCMOS outputs

are controlled by separate supply voltages to allow for

independent voltage level control. The frequencies of

the outrputs can be identical or independently derived

from a common PLL frequency source.

The DSC2011FE2-F0016 has provision for up to eight

user-defined pre-programmed, pin-selectable output

frequency combinations. The DSC2011FE2-F0016 is

also equipped with independent pin-selectable output

drive strengths to reduce EMI and noise.
