SiT3373
220 MHz to 725 MHz Ultra-low Jitter Differential VCXO
Description
The
SiT3373
is a 220.000001 MHz to 725 MHz
differential MEMS VCXO engineered for low-jitter
applications. Utilizing SiTime’s unique DualMEMS™
temperature
sensing
and
TurboCompensation™
technology, the SiT3373 delivers exceptional dynamic
performance by providing resistance to airflow, thermal
gradients, shock and vibration. This device also
integrates multiple on-chip regulators to filter power
supply noise, eliminating the need for a dedicated
external LDO.
The SiT3373 can be factory programmed for any
combination of frequency, stability, voltage, output
signaling, and pull range. Programmability enables
designers to optimize clock configurations while
eliminating long lead times and customization costs
associated with quartz devices where each frequency is
custom built.
The wide frequency range and programmability makes
this device ideal for telecom, networking, and industrial
applications that require a variety of pullable frequencies
and operate in noisy environments.
Refer to
Manufacturing
Notes
for proper reflow profile,
tape and reel dimension, and other manufacturing
related information.
