[Mark] from SpikenzieLabs was wrapping up a project using an Arduino the other day and found himself in need of a few more I/O pins. He could have added extra circuitry to the project, but he decid… ...

A newer type of oscillator, which has been in development since the 1960s and available in production volumes since 2005, is the microelectromechanical-system (MEMS) resonator clock.

At 40.0MHz the phase noise performance of IQD’s CFPS-115 crystal clock oscillator is -80dBc/Hz at 10Hz offset and -145dBc/Hz at 1kHz offset. Low power consumption is specified at 7mA. The device is ...
