The DSC1101BI2-125.0037T is a MEMS-based XO that delivers a precise 125.0037 MHz CMOS clock from a 6-VDFN package — no quartz crystal to source, no external load capacitors to place.
Rated for 2.25V to 3.6V supply, the oscillator runs directly off a 2.5V or 3.3V rail without a series regulator — one less part on the BOM.
Microchip lists the DSC1101BI2-125.0037T as Active.
Yes — the function is listed as Standby (Power Down). When disabled, the supply current drops to 95 µA max, allowing the oscillator to be gated off in low-power sleep states without removing the supply rail.
Yes — the supply range is 2.25V to 3.6V, so a 3.3V rail is within the operating envelope. No external regulator needed.
