Field Programmable Oscillator
Description
SiTime offers a wide range of field programmable (FP)
MEMS oscillators including simple oscillators, differential
oscillators, high temperature oscillators, VCXO and
spread spectrum oscillators. These FP devices support
the same specifications and performance as their factory-
programmed counterparts.
They enable engineers to experiment with different
configurations and generate customized samples in
seconds for fast prototyping.
Figure 1
illustrates the simple programming setup
required for programming SiTime FP devices by using
the SiT6100DK, a field programming kit. Refer to
SiT6100DK quick start guide and
other documents for
more information.
For production volume, SiTime offers factory
programming of its entire portfolio with the shortest lead
time available in the industry.
