Product details

Dual HCSL clock for PCIe and Ethernet reference

The DSC2044FE2-F0018T is a MEMS-based XO that delivers two HCSL outputs at 100 MHz and 125 MHz simultaneously — the two most common reference frequencies for PCIe Gen1/2/3 and 1 GbE / 10 GbE PHYs.

Housed in a 14-VFQFN Exposed Pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm height. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an external regulator.
