MEMS oscillator for wide-temperature clocking
The DSC1101DM1-040.0000 is a MEMS-based XO (Standard) from Microchip Technology's DSC1101 series, delivering a 40 MHz CMOS output with ±50 ppm frequency stability. The MEMS resonator replaces a quartz crystal, giving better shock and vibration immunity and faster start-up than a conventional oscillator.
Standby function and wide supply flexibility
A dedicated Standby (Power Down) pin disables the output and drops supply current to 95 µA max, useful for battery-powered or intermittent-duty systems that need to gate the clock tree. The supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V logic rails without an external LDO, simplifying power distribution.
Package and board-fit considerations
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator occupies minimal PCB area and suits space-constrained designs. Maximum supply current is 35 mA at 40 MHz, so the thermal dissipation in the small package is manageable even at the high end of the temperature range.
