SiT5155
±0.5 ppm, Elite Platform™ Super-TCXO for GNSS/GPS
Description
The
SiT5155
is a ±0.5 ppm MEMS Super-TCXO that is
Features
engineered for high reliability, GNSS-based precision
positioning and timing applications.
Leveraging SiTime’s unique DualMEMS™ temperature
sensing and TurboCompensation™ technologies, the
SiT5155 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 SiT5155 offers three device configurations that can be
ordered using
Ordering Codes
for:
12 frequencies from 10 MHz to 40 MHz
Factory programmable options for short lead time
Best dynamic stability under airflow, thermal shock
±0.5 ppm stability across temperature
±15 ppb/°C typical frequency slope (ΔF/ΔT)
-40°C to +105°C operating temperature
No activity dips or micro jumps
Resistant to shock, vibration and board bending
On-chip regulators eliminate the need for external LDOs
Digital frequency pulling (DCTCXO) via I
2
C
Digital control of output frequency and pull range
Up to
±3200
ppm pull range
Frequency pull resolution down to 5 ppt
2.5 V, 2.8 V, 3.0 V and 3.3 V supply voltage
LVCMOS or clipped sinewave output
RoHS and REACH compliant
Pb-free, Halogen-free, Antimony-free
Applications
The SiT5155 can be factory programmed for specific
combinations of frequency, 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.

Manufacturing Guideline
for proper reflow profile
and PCB cleaning recommendations to ensure best
performance.
