DSC2011FI2-F0016
Crystal-less™ Configurable Clock Generator
General Description
The DSC2011FI2-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 DSC2011FI2-F0016 has provision for up to eight
user-defined pre-programmed, pin-selectable output
frequency combinations. The DSC2011FI2-F0016 is
also equipped with independent pin-selectable output
drive strengths to reduce EMI and noise.
