Product details

Quad-output MEMS XO for multi-rate timing trees

The DSC400-4444Q0015KE1 is a MEMS-based XO (Standard) that delivers four independent HCSL clock outputs from a single 20-VFQFN package — two banks: outputs 1 at 25/50/125/150 MHz and outputs 2 at 100/156.25 MHz.

Supply flexibility and frequency stability

The 2.25V–3.6V supply range lets this part work on a 2.5V or 3.3V rail without a dedicated LDO — one less component on the board.

The 20-VFQFN package with exposed pad is a standard reflow profile; no special moisture sensitivity handling beyond the MSL label on the reel.
