SiT5156
Description
PRELIMINARY
1 to 60 MHz,
±0.5
ppm Elite Platform™ Super-TCXO
Features
The
SiT5156
is a ±0.5 to ±2.5 ppm MEMS Super-TCXO
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
SiT5156 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 SiT5156 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
SiT5156 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.
Any frequency between 1 MHz and 60 MHz in
1 Hz steps
Excellent dynamic stability under airflow and rapid
temperature change
±500 ppb 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
Microwave backhaul
Network switches and routers

Why is my MOSFET always on?
[i=s]This post was last edited by dontium on 2015-1-23 12:51[/i] It’s so strange... The gate is driven and the duty cycle is 50%, so why are the D and S pole voltages almost always equal?...

Ask about the calculation of the baud rate of the msp430 serial port
I read in the user manual that if the clock is 32.768K and the baud rate is set to 9600, then uxbr0 = 0x03, uxmctl = 0x4a. I don't quite understand the origin of uxmctl = 0x4a. According to the formul...
