The DSC1001AE2-027.0000T is a 27 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to +70°C operating range. The supply voltage spans 1.8V to 3.3V, covering the common digital rails without an external LDO; the 7.2 mA max supply current at 27 MHz keeps the thermal budget low in a sealed enclosure.
Standby function for battery-backed systems
Package and board-fit details
Housed in a 4-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many 7x5 mm XO patterns, simplifying a drop-in replacement for quartz oscillators.
