SiT5156
Description
1 MHz to 60 MHz, ±0.5 to ±2.5 ppm, Elite Platform™ Super-TCXO
Features
TCXO that is engineered for best dynamic performance. It
is ideal for high reliability telecom, wireless and networking,
industrial, precision GNSS and audio/video applications.
Leveraging SiTime’s unique DualMEMS™ temperature
sensing and TurboCompensation™ technologies, the
SiT5156 delivers the best dynamic performance for timing
stability in the presence of environmental stressors such as
air flow, temperature perturbation, vibration, shock, and
electromagnetic interference. This device also integrates
multiple on-chip regulators to filter power supply noise,
eliminating the need for a dedicated external LDO.
The SiT5156 offers three device configurations that can be
ordered using
Ordering Codes
for:
1) TCXO with non-pullable output frequency,
2) VCTCXO allowing voltage control of output
frequency, and
3) DCTCXO, enabling digital control of output frequency
2
using an I C interface, pullable to 5 ppt (parts per
trillion) resolution.
The SiT5156 can be factory programmed for any
combination of frequency, stability, voltage, 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 Guideline
for proper reflow profile
and PCB cleaning recommendations to ensure best
performance.
The
SiT5156
is a ±0.5 ppm to ±2.5 ppm MEMS Super-
