The DSC1101DL2-025.0000T is a 25 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a CMOS output. Unlike a quartz crystal, the MEMS resonator is inherently more shock- and vibration-tolerant, and starts up faster — no startup jitter from a crystal's motional inductance. The wide supply range (2.25V to 3.6V) lets it run directly off a 2.5V or 3.3V rail without an extra LDO — one less part on the BOM.
Standby function and power budget
A dedicated Standby (Power Down) pin drops the supply current to 95 µA max when the oscillator is disabled — useful for battery-operated sensors or IoT nodes that sleep most of the time and wake only to transmit. When active, the part draws 35 mA max at 25 MHz — a typical figure for a CMOS-output MEMS oscillator at this frequency. Budget this into the rail's current capacity; it's not a low-power oscillator but a general-purpose one.
Package and board layout
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits space-constrained PCBs.
