Frequently asked questions
Can the DSC1001CI5-020.0000 replace a standard quartz crystal oscillator?
Yes, this is a MEMS-based XO (Standard) with a CMOS output at 20 MHz, so it is a direct replacement for a quartz crystal oscillator in the same frequency and output logic. The MEMS resonator is more shock- and vibration-tolerant than quartz, and the part includes a standby power-down function that a basic quartz oscillator may not offer.
