Micro-electro-mechanical systems (MEMS) enable system clocks to fit into a few square millimeters, and now cover a larger range of available frequencies. Look for migration to MEMS oscillators that reduce further the size of mobile electronic devices over the next five years. RColinJohnson @ NextGenLog
SiTime fills out its low-end with the world's first kHz-range MEMS silicon oscillator chip.
Here is what EETimes says about MEMS oscillators: SiTime Corp. has fielded what it says is the first kilohertz-range microelectromechanical system (MEMS) oscillator chip. The SiT8503 covers the 200-kHz to 1,000-kHz range with claimed five-decimal-place accuracy...SiTime already claims to have the broadest portfolio of MEMS-based silicon oscillators, voltage-controlled oscillators, resonators, clock generators and spread-spectrum timing products. With the addition of a kilohertz offering, it hopes to become a one-stop-shop for all the timing needs of application developers...
