Description
PRELIMINARY
±0.5
ppm Elite Platform™ Precision Super-TCXO for GNSS/GPS
Features
The
SiT5155
is a ±0.5 ppm MEMS Super-TCXO
engineered for high accuracy GNSS based positioning and
timing applications.
By leveraging SiTime’s unique DualMEMS™ temperature
sensing and TurboCompensation™ technology, the
SiT5155 delivers the most stable timing in the presence of
environmental stressors – air flow, temperature
perturbation, vibration, shock and electromagnetic
interference (EMI). This device also integrates multiple on-
chip regulators, providing power supply noise filtering and
eliminating the need for a dedicated external LDO.
The SiT5155 offers three device configurations that can be
ordered with the associated
ordering codes:
1)
2)
3)
TCXO with non-pullable output frequency
VCTCXO allowing voltage control of output frequency
DCTCXO enabling digital control of the output
2
frequency through the I C interface
SiT5155 can be factory-programmed to any combination of
frequency, stability, voltage, and pull range. This
programmability enables designers to optimize the clock
configuration while eliminating the long lead time and
customization cost associated with quartz TCXOs where
each frequency is custom built.
13 common GNSS frequencies
Excellent dynamic stability under airflow and rapid
temperature change
±0.5 ppm over-temperature stability
±15
ppb/C frequency slope (ΔF/ΔT)
3e-11 ADEV at 10 second averaging time
No activity dips or micro jumps
Resistant to shock, vibration and board bending
Up to ±3200 ppm pull range (VCTCXO or DCTCXO)
2
Digital frequency pulling (DCTCXO) via I C
Digital control of output frequency and pull range
Frequency pull resolution as low as 5 ppt (0.005 ppb)
-40°C to +85°C operating temperature, contact
SiTime
for +105C option
2.5V, 2.8V, 3.0V and 3.3V supply voltage
On-chip regulators, eliminating the need for the
external LDO
LVCMOS or clipped sinewave output
RoHS and REACH compliant, Pb-free, Halogen-free
and Antimony-free
Applications
Precision GNSS for agriculture, construction and
Surveying
Precision GNSS for Mobile mapping, marine and
aerospace
GPS, Galileo, Beidou and other GNSS systems
