Active dual-output MEMS oscillator for mixed-frequency clocks
The DSC2011FI2-F0017 is an active-production MEMS-based XO that delivers two independent CMOS clock outputs from a single resonator — 24 MHz on Output 1 and either 100 MHz or 200 MHz on Output 2, selectable via the part number configuration.
Supply flexibility and enable/disable control
The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails without an intermediate regulator — one less part on the BOM and one less voltage drop to budget.
The 14-VFQFN exposed-pad package (3.20mm x 2.50mm, 0.90mm height) needs a thermal via pattern under the pad for heat sinking — the exposed pad is electrically connected to the die attach, so the PCB layout should tie it to the ground plane for both thermal and noise reasons.
