The DSC1001BL5-080.0000T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering an 80 MHz CMOS clock with ±10 ppm frequency stability across a 1.8V to 3.3V supply range.
The 1.8V to 3.3V supply range covers 1.8V, 2.5V, and 3.3V logic rails without an external level translator — a single BOM line serves multiple voltage domains across a platform.
Package, footprint, and layout notes
Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard 5×3.2 mm oscillator footprint that matches many quartz XO land patterns, simplifying a drop-in MEMS substitution. The CMOS output eliminates the need for external termination resistors required by differential clocks, saving two passives per oscillator on the BOM.
