Product details

MEMS resonator with HCSL output

The DSC1214CI3-C0020 is a MEMS-based oscillator from Microchip's DSC12X4 series, delivering an HCSL output — the differential logic family specified for PCIe reference clocks and high-speed serial links. Operating from a 2.25 V to 3.63 V supply, the device draws 40 mA typical at full load.

Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1214CI3-C0020 occupies a footprint comparable to a standard quartz oscillator in a 2.5 x 3.2 mm ceramic package.

Frequently asked questions

Can DSC1214CI3-C0020 replace a quartz oscillator in a PCIe clock application?

Yes, the HCSL output is the standard logic family for PCIe reference clocks. The MEMS resonator provides equivalent frequency stability (±20 ppm) over the industrial temperature range, with the advantage of faster startup and lower aging drift compared to quartz. Verify the supply voltage (2.25 V–3.63 V) and package footprint (6-VDFN, 3.2 x 2.5 mm) match the existing PCB layout.
