Product details

100 MHz HCSL clock from a MEMS resonator

Its HCSL output is the differential clock standard used by PCIe, SATA, and other high-speed serial interfaces — the 100 MHz frequency is the reference for PCIe Gen 1/2/3 root complexes and switches. Supply voltage spans 2.25V to 3.6V, so it can run from a 2.5V or 3.3V rail without an extra regulator. The wide tolerance also helps if the rail droops under load.

Standby (power down) and disable current

Package, footprint, and temperature grade

Housed in a 6-VDFN exposed pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. Not qualified for automotive or extended industrial environments where -40°C operation is required.

Frequently asked questions

How can I order DSC1104AE1-100.0000 or check stock?

This part is Active and available through independent distribution. Submit an RFQ with your target quantity — we source against your BOM line and confirm availability and current pricing at quote time. No stock-holding claim; every order is quoted to order.

What output type does DSC1104AE1-100.0000 have?

HCSL (High-Speed Current Steering Logic) — a differential output standard used for PCIe reference clocks. It requires 50-ohm termination to ground at the receiver, typically via a pair of resistors. The swing is about 700 mV peak-to-peak differential.
