SiT5346
1 MHz – 60 MHz, ±0.1 to ±0.25 ppm,
Endura™ Series Precision Super-TCXO
Description
The
SiT5346
is a ruggedized ±100 ppb precision MEMS
Super-TCXO with a maximum acceleration sensitivity of
0.009 ppb/g or 0.1 ppb/g. Fully compliant to Telcordia GR-
1244-CORE Stratum 3 oscillator specifications, and
engineered for best dynamic performance, the SiT5346 is
ideal for high reliability defense, space, avionics, guidance,
precision GNSS and communications applications.
Leveraging SiTime’s unique DualMEMS™ temperature
sensing and TurboCompensation™ technologies, the
SiT5346 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 SiT5346 offers three device configurations that can be
ordered using
Ordering Codes
for:
Features
Any frequency from 1 MHz to 60 MHz in 1 Hz steps
Factory programmable options for short lead time
Best dynamic stability under airflow, thermal shock
0.009 ppb/g or 0.1 ppb/g acceleration sensitivity
±100 ppb stability across temperature
±1 ppb/C typical frequency slope (ΔF/ΔT)
1.5e-11 ADEV at 10 second averaging time
-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

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 SiT5346 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.
