Product details

The DSC1001BI2-012.2888T is a surface-mount MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 12.2888 MHz CMOS output.

Operating from 1.8V to 3.3V, the oscillator can be powered directly from a 1.8V core rail or a 3.3V I/O rail without an external regulator.

Package footprint and board layout

Housed in a 4-SMD, no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. The 0.197" x 0.126" footprint matches industry-standard 5x3.2mm oscillator pads, so it is a drop-in replacement for many quartz oscillators of the same size. The no-lead package requires a solder-paste stencil aperture matching the pad layout — no through-hole or hand-solder step.

Sourced through independent distribution channels. No minimum order quantity constraints beyond standard reel increments.

Frequently asked questions

Is the DSC1001BI2-012.2888T AEC-Q100 qualified?

Yes, it is rated AEC-Q100, which qualifies it for automotive-grade applications including under-hood and cabin electronics.

What is the standby function on this oscillator?

The standby (power-down) function disables the output and reduces supply current to 15 µA max. This is useful for battery-powered systems that need to conserve power during idle periods.
