The DSC1101DL1-027.0000T is a 27 MHz MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a CMOS output with ±50 ppm frequency stability across its full operating range. Its 2.25V to 3.6V supply range lets it run directly off a 2.5V or 3.3V rail without an extra regulator, simplifying the power tree on mixed-voltage boards.
6-VDFN package and board layout
Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a seated height of 0.90mm, it fits tight PCB real estate and is hand-solderable with a fine-tip iron and magnification. Surface-mount only—no through-hole variant—so plan for a stencil or manual paste deposition during prototyping.
