Dual-frequency MEMS clock in a military-temp envelope
The DSC2011FM1-F0041T is a MEMS-based XO (standard) from Microchip's DSC2011 series, delivering two independent CMOS clock outputs from a single resonator: 25 MHz on output 1 and 125 MHz on output 2. The MEMS resonator itself is inherently more shock- and vibration-tolerant than a quartz blank, and startup time is typically under 5 ms — no crystal oscillator startup delay in a power-cycled system.
Supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an intermediate regulator — one less component on the power tree. Maximum supply current is 32 mA typical when both outputs are enabled; with the enable/disable function pulling the outputs to high-Z, the disable current drops to 23 mA max. The CMOS output swings rail-to-rail, so the 25 MHz and 125 MHz clocks drive standard digital loads directly — no external termination or level translation needed for typical FPGA or MCU clock inputs.
Housed in a 14-VFQFN exposed-pad package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC2011FM1-F0041T fits into space-constrained designs like compact radio modules or sensor hubs. Supplied on tape and reel, it is compatible with standard pick-and-place assembly; no special handling beyond normal MSL precautions.
