SiT9366
Description
1 MHz to 220 MHz Ultra-low Jitter Differential Oscillator
Features
The
SiT9366
is a 1 MHz to 220 MHz differential MEMS
XO engineered for low-jitter applications. Utilizing
SiTime’s unique DualMEMS® temperature sensing and
TurboCompensation® technology, the SiT9366 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 SiT9366 can be factory programmed for any
combination of frequency, stability, voltage, and output
signaling. 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 frequencies and
operate in noisy environments.
Refer to
Manufacturing Notes
for proper reflow profile,
tape and reel dimension, and other manufacturing
related information.
Any frequency between 1 MHz and 220 MHz accurate to
6 decimal places
