Product details

The DSC1001DI2-027.0000T is a 27 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a standard XO function with CMOS output.

Runs on any rail from 1.8V to 3.3V, so it can clock a 1.8V MCU or a 3.3V FPGA without a separate level translator. The wide supply tolerance simplifies BOM consolidation across multiple voltage domains.

Industrial temp range and low power

Maximum supply current is 7.2 mA, and the standby function drops draw to 15 µA when the output is disabled — useful for battery-backed systems that need to idle without draining the rail.

Frequently asked questions

Is DSC1001DI2-027.0000T compatible with a 1.8V supply?

Yes. The supply range is 1.8V to 3.3V, so it runs directly on a 1.8V rail without an external regulator.

Is DSC1001DI2-027.0000T automotive qualified?

Yes, it carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability testing including temperature cycling and ESD stress. Suitable for under-hood and cabin applications within its -40°C to 85°C range.

How does the standby function work on DSC1001DI2-027.0000T?

The standby (power-down) pin disables the output and drops current consumption to 15 µA max. The oscillator stops; when brought out of standby, the output resumes after the start-up settling time. Use it for power gating in battery-operated designs.

Is DSC1001DI2-027.0000T a drop-in replacement for quartz oscillators?

The DSC1001DI2-027.0000T is a MEMS oscillator in a standard 4-SMD no-lead package (2.5mm x 2.0mm). It is footprint-compatible with many quartz XO packages of the same size, but confirm the pinout and output type (CMOS) against your existing quartz part. MEMS oscillators generally offer better shock and vibration tolerance than quartz.
