MEMS oscillator reference clocks for industrial IoT

June 13, 2017 // By Graham Prophet
SiTime’s SiT1569 oscillator and SiT1576 Super-TCXO offer expanded frequency range of 1 Hz to 2 MHz, for ultra-low-power MCUs and AFEs (analogue front-ends). They offer 2 µA power demand and ±5 ppm accuracy, in a 1.2 mm2 CSP (chip-scale package) footprint.

Using SiTime’s TempFlat MEMS and mixed-signal technology, these devices deliver increased timekeeping accuracy and system power savings. The ultra-reliable, low-jitter SiT1576 and SiT1569 reference clocks are designed to drive microcontrollers (MCUs) and analogue front end (AFE) modules in a range of portable and IoT applications such as railroad activity sensors in harsh environments, seismic sensor interface applications, and personal medical diagnostics.


The MEMS timing solutions replace quartz oscillators that have limited frequency options, or internally-generated (MCU) power-hungry frequencies that lack accuracy and consume I/O pins.
