Product details

MEMS oscillator for industrial clock trees

The DSC1033BI1-012.0000 is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 12 MHz CMOS output with ±50 ppm frequency stability across -40°C to 85°C.

Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1033BI1-012.0000 fits standard 5x3.2 mm oscillator footprints. The no-lead construction eliminates side-castellation solder joints; the pad layout under the body should match the recommended land pattern for 4-pin ceramic SMD oscillators to avoid tombstoning during reflow. Surface-mount assembly with the 0.90 mm profile clears typical board-to-board clearance constraints in stacked mezzanine designs. No external load capacitors are required — the MEMS resonator and output driver are self-contained.

Sourcing posture and lifecycle

Frequently asked questions

How can I order the DSC1033BI1-012.0000 or check current availability?

The DSC1033BI1-012.0000 is an active Microchip part sourced through independent distribution. Submit an RFQ with your target quantity; we confirm pricing and lead time against that specific order. No stock-holding claim is made on this page.

What is the output type of the DSC1033BI1-012.0000?

CMOS output — the oscillator drives standard 3.3 V logic levels directly, compatible with most MCU and FPGA clock inputs without external level translation.

Does the DSC1033BI1-012.0000 require external load capacitors?

No. As a MEMS-based XO, the resonator and output driver are self-contained in the 4-pin package. No external load capacitors are needed — the output is a rail-to-rail CMOS signal ready for the clock input.
