Programmable MEMS oscillator for flexible clock trees
The DSC1101BL5-PROGT is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a CMOS output across a programmable frequency range of 2.3 MHz to 170 MHz. Unlike a fixed-frequency crystal oscillator, this part ships as a blank device that must be programmed to the desired output frequency before use — a key distinction for BOM planning and prototype turnaround.
The supply voltage range of 2.25V to 3.6V lets it run from common 2.5V or 3.3V rails without an external regulator.
Standby function and package footprint
The 6-VDFN package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm, a standard footprint that matches many quartz oscillator land patterns.
