Product details

It is part of Microchip's DSC1001 series and comes in a 4-VDFN surface-mount package measuring 3.20 mm x 2.50 mm.

Supply voltage and power-down standby

Supply voltage spans 1.7V to 3.6V, so the oscillator can be powered directly from a 1.8V, 2.5V, or 3.3V rail without an intermediate regulator. This is useful for battery-powered modules that need to cut clock power between active cycles. Active current consumption is 6.5 mA max at the rated frequency — a reasonable draw for a precision clock source in a mixed-signal system.

Frequently asked questions

Is the DSC1001CL1-018.4320T compatible with AEC-Q100 automotive requirements?

Yes. The oscillator is rated AEC-Q100, which means it has passed the automotive-grade qualification tests for temperature, reliability, and PPAP documentation. It is suitable for deployment in under-hood and cabin electronic modules.

Does the DSC1001CL1-018.4320T have a standby mode?

Yes. The function is listed as Standby (Power Down). When the enable pin is deasserted, the output stops and the supply current drops to 15 µA max.

What is the footprint of the DSC1001CL1-018.4320T?

The package is a 4-VDFN measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The exact land pattern is in the datasheet; the small footprint suits space-constrained PCB layouts.
