DSC1001CI2-038.4000 Microchip MEMS Oscillator 38.4 MHz CMOS

The DSC1001CI2-038.4000 is a 38.4 MHz XO (Standard) oscillator from Microchip's DSC1001 series, built on a MEMS resonator rather than a quartz crystal. The CMOS output delivers a rail-to-rail square wave that drives most digital clock inputs directly — no external termination or level translation needed for 1.8 V to 3.3 V logic families.

The Standby (Power Down) function drops the supply current to 15 µA max when the enable pin is de-asserted — useful for battery-backed RTC or CAN wake-up circuits where the oscillator must stop drawing its full 7.2 mA during sleep. The 7.2 mA max supply current at 38.4 MHz is typical for a MEMS oscillator at this frequency; the CMOS output swing is the main power draw, not the resonator itself.
