Product details

100 MHz MEMS oscillator with HCSL output – active and available

HCSL swings 700–900 mV peak-to-peak into a 50-Ω termination to ground, which means the output stage is DC-coupled to the receiver without a series capacitor — a layout simplification on high-speed serial interfaces. Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without a separate LDO; the wide input tolerance reduces BOM count on multi-voltage boards.

Package and footprint – 7.0×5.0 mm 6-SMD

Housed in a 7.00 mm × 5.00 mm 6-SMD no-lead package, seated height 0.90 mm max — a standard footprint shared with many 7×5 oscillators, easing second-sourcing or layout reuse.

Frequently asked questions

What is the output type of the DSC1124NE1-100.0000T?

HCSL (High-Speed Current Steering Logic) — a differential output that swings 700–900 mV into a 50-Ω termination to ground. It is the standard reference clock format for PCIe Gen1/2/3, SATA, and 1 GbE PHYs.

Is the DSC1124NE1-100.0000T a MEMS oscillator?

Yes, the base resonator is MEMS, not quartz. MEMS oscillators offer faster start-up, better shock/vibration tolerance, and smaller package options compared to traditional crystal-based XOs.
