Four 50 MHz outputs from a single MEMS resonator
Each output runs at the same 50 MHz frequency, which means a single oscillator can clock a CPU, an FPGA bank, an Ethernet PHY, and a USB controller from one source — the phase noise profile is identical across all four lanes.
Operating from 2.25 V to 3.6 V, the part covers 2.5 V and 3.3 V logic rails without an external regulator — the wide input tolerance absorbs rail droop from a switching converter.
Package and layout — 20-VFQFN with exposed pad
Housed in a 20-VFQFN with an exposed thermal pad, the 5.00 mm x 3.20 mm footprint matches standard oscillator land patterns — the pad must be soldered to a ground plane with thermal vias to keep the junction temperature within the commercial range.
