The DSC1101DM2-007.3700T is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a 7.37 MHz CMOS clock output.
Standby function for power-gated designs
In a battery-backed RTC or a sensor node that sleeps between reads, the oscillator's own draw becomes negligible compared to the rest of the system. The supply voltage range spans 2.25V to 3.6V, so the same part runs from a 2.5V or 3.3V rail without an intermediate LDO — one fewer component in the power tree.
