40 MHz MEMS oscillator with wide supply tolerance
The DSC1101CL5-040.0000T is a 40 MHz MEMS-based XO (standard) from Microchip's DSC1101 series, delivering a CMOS output from a 2.25V to 3.6V supply rail — it runs on 3.3V, 2.5V, or anything between without a separate regulator. The 6-SMD no-lead package (3.20 mm x 2.50 mm footprint, 0.90 mm seated height) is a common MEMS-oscillator land pattern; it sits on the same PCB footprint as many quartz oscillators of similar size.
No stock-holding claim — each quote reflects the multi-source reach at that moment.
Why a MEMS resonator matters here
The 35 mA max supply current at 40 MHz is competitive with quartz oscillators of the same output type; the standby current of 95 µA is the real differentiator for designs that must pass a low-power idle test.
