Elite Platform™ Precision Super-TCXO
Features
The
SiT5356
is a ±100 ppb precision MEMS Super-TCXO
that is fully compliant to the GR-1244 Stratum 3 oscillator
specifications. This device is engineered for best dynamic
performance. It is ideal for high reliability telecom, wireless
and networking, industrial, precision GNSS and
audio/video applications.
By leveraging SiTime’s unique DualMEMS™ temperature
sensing and TurboCompensation™ technology, the
SiT5356 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 SiT5356 offers three device configurations that can be
ordered with the associated
ordering codes:
1)
2)
TCXO with non-pullable output frequency
VCTCXO allowing voltage control of output frequency
3)
DCTCXO enabling digital control of the output

frequency through the I C interface
Any frequency between 1 MHz and 60 MHz in
1 Hz steps
Exceptional dynamic stability under airflow, thermal
shock
±100 ppb over-temperature stability
±2.5
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)

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
On-chip regulators, eliminating the need for an
external LDO
2.5V, 2.8V, 3.0V and 3.3V supply voltage
LVCMOS or clipped sinewave output
RoHS and REACH compliant, Pb-free, Halogen-free
and Antimony-free
SiT5356 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.
