Using SiTimes’ SOI-MEMS based oscillator can extend battery life by a full day in some apps, Piyush Sevalia, Executive Vice President, Marketing for SiTime explained in a recent Planet Analog piece (read the whole thing here).
The traditional timing device is a quartz (passive crystal) resonator, which doesn’t draw any power itself. But it doesn’t save any either. As Piyush describes:
In a portable audio application for example, a SiT8021 oscillator operating at 3.072 MHz draws only 60 μ A compared to a quartz oscillator at 2.5 mA. In this case, the power consumption is 98% lower. This can effectively extend battery life by a full day – a huge improvement.
SiTime is a Bosch spin-off that’s now part of Megachips Corporation. The SiTime CTO first described their SOI-MEMS fabrication technology for ASN back in 2009 (read that here). Since then, they’ve shipped more than 300 million devices and captured 80% market share. Click here for more about SiTime’s SOI-MEMS solutions in ASN.
