The DSC6001HE3B-027.1200 is a 27.12 MHz XO (Standard) oscillator from Microchip's DSC60XXB series, built around a MEMS resonator rather than a quartz crystal. It outputs a CMOS-level clock and includes an Enable/Disable function for power management on the clock line. The supply voltage range of 1.71V to 3.63V covers common 1.8V, 2.5V, and 3.3V rails, so it fits into a mixed-voltage design without a dedicated regulator for the oscillator.
Housed in a 4-VFLGA package measuring 1.60mm x 1.20mm with a seated height of 0.89mm, this oscillator is a surface-mount part that suits space-constrained layouts.
No direct pin-compatible second source or successor is listed; the DSC60XXB series is Microchip's own MEMS oscillator family. For volume commitments, confirm the lead time at quote.
