SiT5156
Description
1 MHz to 60 MHz, ±0.5 to ±2.5 ppm, Elite Platform™ Super-TCXO
Features
The
SiT5156
is a ±0.5 ppm to ±2.5 ppm MEMS Super-
TCXO that is 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
SiT5156 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 SiT5156 offers three device configurations that can be
ordered using
Ordering Codes
for:
Any frequency from 1 MHz to 60 MHz in 1 Hz steps
Factory programmable options for short lead times
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 SiT5156 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.

一位射频工程师分享的感想
十年了,依然两手空空。回首一望,心里无比苍凉。 由于学历比较低吧,知名的企业进不了。也就一些小公司看在我经验丰富的份上要了我,工资老涨不上去;而且那些公司确确实实是要会干活的人 ......

Sigh,刚才do evil了一把
1、封了一个发非法广告的; 2、抓住一个为了赚分灌纯净水的,把纯净水统统删掉了。 删完以后,这哥们倒欠31个芯币了…… 没辙:)...
