45.1584 MHz MEMS XO with standby power-down
The DSC1101DE2-045.1584 is a MEMS-based XO (Standard) that outputs a 45.1584 MHz CMOS clock from a 2.25V to 3.6V supply rail, drawing a maximum of 95 µA. The standby (power-down) function pulls the output to high-impedance and drops the core current to near-zero — useful for battery-powered designs that gate the clock during sleep and wake on a timer or external event.
Active production — no last-time-buy window
Microchip lists the DSC1101DE2-045.1584 as Active.
Housed in a 6-VDFN package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The operating temperature range is -20°C to +70°C — commercial-grade, suited for indoor equipment, office electronics, and appliance PCBs where ambient stays within that band. Surface-mount assembly with standard reflow profiles; the small footprint frees board area for other routing.
