The DSC6001JI2B-022.5792T is a MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a 22.5792 MHz CMOS output with ±25 ppm frequency stability across -40°C to 85°C.
The 1.71V to 3.63V supply range lets this oscillator run directly off a 1.8V, 2.5V, or 3.3V rail without an intermediate LDO—useful in multi-voltage designs where the clock rail is already present.
Package Footprint and Board-Level Fit
Housed in a 2.50 mm × 2.00 mm 4-SMD no-lead package, this oscillator occupies roughly the same PCB area as a 2012-size capacitor. The 0.89 mm seated height suits tight mezzanine or stacked-board assemblies. Surface-mount reflow follows standard JEDEC profiles; no special bake-out is needed for MEMS devices.
No direct second-source is listed, but the DSC60XX family includes multiple frequency and stability variants sharing the same footprint.
