SiT3342
1 MHz to 220 MHz Ultra-low Jitter, Endura™ Series Differential VCXO
Description
The
SiT3342
is a ruggedized 1 MHz to 220 MHz
differential MEMS VCXO with a maximum acceleration
sensitivity of 0.1 ppb/g, engineered for low-jitter
applications. Utilizing SiTime’s unique DualMEMS
®
temperature
sensing
and
TurboCompensation
®
technology, the SiT3342 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
SiT3342
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.
Refer to
Manufacturing Notes
for proper reflow profile,
tape and reel dimension, and other manufacturing
related information.
Features
Best acceleration sensitivity of 0.1 ppb/g
Any frequency between 1 MHz and 220 MHz accurate
to 6 decimal places
Widest pull range options: ±25, ±50, ±80, ±100, ±150,
±200, ±400, ±800, ±1600, ±3200 ppm
0.225 ps RMS phase jitter (typ) over 12 kHz to 20 MHz
bandwidth
Frequency stability as low as ±15 ppm
Wide temperature range support from -40°C to 105°C
Industry-standard packages: 7.0 x 5.0 mm,
5.0 x 3.2 mm, 3.2 x 2.5 mm packages
Applications
