Product details

MEMS oscillator at 125 MHz — active production

HCSL output and supply range

HCSL (High-Speed Current Steering Logic) output is the de facto standard for PCIe reference clocks and many high-speed SerDes interfaces.

Industrial temperature and ±20 ppm stability

6-VDFN package — board layout note

The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm. Surface-mount assembly on standard FR-4; the small footprint frees board area for other routing. No exposed pad — the thermal path is through the package body and solder joints.

Frequently asked questions

Is DSC1124DL3-125.0000T compatible with HCSL logic?

Yes, the output is HCSL. It drives PCIe reference clocks and other HCSL inputs directly. For LVDS or LVPECL loads, a level translator or AC-coupling with termination resistors is needed.

Can DSC1124DL3-125.0000T replace a quartz oscillator?

Functionally yes — it is a drop-in MEMS replacement for a 125 MHz HCSL quartz oscillator in the same 6-VDFN footprint. The MEMS version offers better shock and vibration tolerance, no crystal aging drift, and faster start-up.
