Product details

Active MEMS oscillator for 1.8V LVCMOS clock trees

The DSC1505AI3A-26M00000T is a MEMS-based XO (Standard) oscillator from Microchip's DSC150X series, delivering a 26 MHz LVCMOS output from a 1.8V supply rail.

Industrial temperature grade and standby power-down

The 7.5 mA max active current is typical for a 26 MHz MEMS oscillator at 1.8V.

Package and footprint for pick-and-place

Housed in a 4-VDFN exposed pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. Surface-mount, supplied on tape and reel.

Frequently asked questions

What is the output type and supply voltage for the DSC1505AI3A-26M00000T?

LVCMOS output from a 1.8V supply rail. It is not compatible with 3.3V logic without a level translator — the output swing is 0 to 1.8V, so a 3.3V receiver may not recognize the high level.

Can the DSC1505AI3A-26M00000T replace a quartz oscillator in a 26 MHz 1.8V design?

Yes, if the board already has a 1.8V supply and expects a standard LVCMOS clock input. The MEMS oscillator drops in with the same 4-pin footprint as many quartz XOs in the 7.0mm x 5.0mm package. No external load capacitors are needed — the MEMS resonator is self-contained. Confirm the enable polarity matches your design's standby logic.
