Product details

MEMS resonator replaces quartz in this 37.125 MHz XO

The DSC1033CI2-037.1250T is a MEMS-based oscillator (XO) from Microchip's PureSilicon™ series, outputting a fixed 37.125 MHz CMOS clock from a 3.3V rail. Unlike quartz crystal oscillators, the MEMS resonator is immune to vibration-induced frequency shifts and has no crystal aging drift—a practical advantage for industrial environments where mechanical shock is present.

Standby mode cuts supply to 1 µA for battery-powered holds

Industrial temperature grade and 3.2 mm × 2.5 mm footprint

The 4-SMD no-lead package measures 3.20 mm × 2.50 mm with a seated height of 0.90 mm—compatible with standard reflow profiles and tight board stacks.

Frequently asked questions

Is the DSC1033CI2-037.1250T a drop-in replacement for a standard 37.125 MHz crystal oscillator?

It is a direct functional replacement for a 3.3V, CMOS-output, 37.125 MHz XO in a 4-SMD no-lead package. The MEMS resonator eliminates quartz aging and vibration sensitivity, but the pinout and supply voltage match the standard footprint—confirm your PCB's enable/power-down pin assignment against the datasheet.

Does the DSC1033CI2-037.1250T have a standby mode?

Yes, the function is Standby (Power Down). When the enable pin is deasserted, the oscillator draws 1 µA maximum, allowing the clock to be gated without an external load switch.
