Product details

The DSC1001DI2-018.4320T is an 18.432 MHz MEMS-based XO that delivers a CMOS output with ±25 ppm frequency stability — a common clock for MCUs, CAN transceivers, and serial buses where the ppm budget must hold across temperature.

Standby mode and disable current for power-conscious BOMs

This matters for battery-backed modules that must wake on a bus activity interrupt. Supply voltage spans 1.8 V to 3.3 V, so the same oscillator can be shared across a 3.3 V MCU and a 1.8 V FPGA bank without a level translator — one BOM line covers two rails.

The 4-SMD no-lead package (2.50 mm × 2.00 mm, 0.90 mm seated height) uses a standard MEMS-oscillator footprint shared across the DSC1001 family. No pin-compatible alternate is listed; the base product number DSC1001 covers multiple frequency and stability variants.

Frequently asked questions

What is the output frequency of DSC1001DI2-018.4320T?

18.432 MHz, CMOS output. That frequency is common for MCU clocks, CAN controllers, and USB full-speed references.

Is DSC1001DI2-018.4320T qualified for automotive use?

Yes — it carries AEC-Q100 rating, which means it passed the automotive IC qualification flow including temperature cycling, ESD, and reliability stress.

Does the DSC1001DI2-018.4320T support 3.3V operation?

Yes. The same part also works at 2.5 V or 1.8 V without a separate regulator.

What is the standby function on the DSC1001DI2-018.4320T?

Standby (power down) disables the output and drops current consumption to 15 µA max. It is a logic-controlled shutdown — useful for battery-powered or intermittent-duty systems that need to cut clock power between active periods.
