SiT5146
PRELIMINARY
1 MHz to 60 MHz, ±0.5 to ±2.5 ppm, Endura™ Series Super-TCXO
Description
The
SiT5146
is a ruggedized ±0.5 to ±2.5 ppm MEMS
Features
Super-TCXO with a maximum acceleration sensitivity of
0.009 ppb/g or 0.1 ppb/g. Engineered for best dynamic
performance, it is ideal for high reliability telecom, wireless
and networking, industrial, precision GNSS and
audio/video applications.
Leveraging SiTime’s unique DualMEMS™ temperature
sensing and TurboCompensation™ technologies, the
SiT5146 delivers the best dynamic performance for timing
stability in the presence of environmental stressors due to
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 SiT5146 offers three device configurations that can be
ordered using
Ordering Codes
for:
1) TCXO with non-pullable output frequency,
2) VCTCXO allowing voltage control of output
frequency, and
3) DCTCXO, enabling digital control of output frequency
using an I
2
C interface, pullable to 5 ppt (parts per
trillion) resolution.
The SiT5146 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.
Refer to
Manufacturing Guideline
for proper reflow profile
and PCB cleaning recommendations to ensure best
performance.
Any frequency from 1 MHz to 60 MHz in 1 Hz steps
Factory programmable options for low lead times
Best dynamic stability under airflow, thermal shock
0.009 ppb/g or 0.1 ppb/g acceleration sensitivity
±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
