Product details

The MEMS resonator core provides inherent shock and vibration immunity compared to quartz-based oscillators, reducing failure risk in high-G environments like engine compartments or portable equipment.

Operating from 1.8V to 3.3V, this oscillator can be powered from a 1.8V core rail or a 3.3V I/O rail without a level translator — the same BOM position works across multiple voltage domains.

Compact 4-VDFN package for space-constrained layouts

Housed in a 2.50mm x 2.00mm 4-VDFN package with a seated height of 0.90 mm, this oscillator fits into tight PCB real estate typical of automotive ECUs, IoT modules, and portable devices. Surface-mount assembly with a small footprint reduces board area compared to larger SMD crystals, though the 4-VDFN requires careful solder paste stencil design to avoid bridging on the narrow pads.

Active production — sourced per RFQ

It is available through independent distribution; quantities are confirmed and quoted against your BOM at RFQ time.

Frequently asked questions

Does the DSC1001DI2-012.2880T require an external load capacitor?

No. As a MEMS oscillator with a CMOS output, the DSC1001DI2-012.2880T generates a rail-to-rail clock signal internally and does not need external load capacitors — unlike a quartz crystal resonator, which requires them for correct oscillation.

Can the DSC1001DI2-012.2880T replace a standard quartz oscillator directly?

Yes, in most cases. The DSC1001DI2-012.2880T is a drop-in replacement for a 12.288 MHz quartz XO with CMOS output, provided the supply voltage (1.8V to 3.3V) and package footprint (4-VDFN) match the existing PCB layout. No external components are needed, and the MEMS core offers better shock resistance.

What is the exact footprint of the DSC1001DI2-012.2880T?

The package is a 4-VDFN measuring 2.50mm x 2.00mm with a seated height of 0.90 mm. The exact pad layout and recommended land pattern are provided in the datasheet — the 4-pin footprint is symmetric, with two corner pins for supply and output.
