Product details

Why choose a MEMS oscillator over quartz for this timing node

Operating from 1.8V to 3.3V, this single oscillator covers 1.8V, 2.5V, and 3.3V logic domains without a separate voltage regulator — one BOM line serves multiple rail voltages.

Package footprint and board layout considerations

Housed in a 4-SMD, No Lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm max, the DSC1001DI1-033.3333 fits tight PCB real estate. The 4-pad land pattern is standard for MEMS oscillators — no via-in-pad required, and the small footprint leaves room for adjacent decoupling caps near the supply pin.

Frequently asked questions

Is DSC1001DI1-033.3333 AEC-Q100 qualified?

Yes, the DSC1001DI1-033.3333 carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and cabin electronics where standard commercial oscillators would not be accepted.

What is the closest pin-compatible alternative to DSC1001DI1-033.3333?

No official pin-compatible second source is listed by Microchip. The DSC1001 series uses a standard 4-SMD, No Lead footprint common to many MEMS oscillators, but electrical compatibility (supply range, output type, stability) must be verified against the target application's timing budget before substitution.
