Product details

MEMS clock source for dual 100MHz lanes

Supply flexibility and output logic selection

Operates from a 2.25V to 3.6V supply rail — the same BOM entry serves 2.5V or 3.3V clock domains without a separate voltage translator. The dual outputs can be independently assigned HCSL or LVPECL, so one device feeds both a PCIe reference clock (HCSL) and a SerDes PLL (LVPECL) on the same board.

Housed in a 20-VFQFN with exposed pad (5.00mm x 3.20mm footprint, 0.90mm height).

The DSC400 series is the current-generation MEMS oscillator family; no pin-compatible successor has been announced.
