The 4-SMD, No Lead package (5.00mm x 3.20mm) is a common footprint shared with many quartz oscillators, making it a drop-in replacement candidate on existing PCB layouts. ## Standby power-down and supply flexibility A dedicated Standby (Power Down) function pulls the output to high-impedance and drops supply current to 15 µA max — useful for battery-powered nodes that sleep between transmissions. The supply voltage range spans 1.8V to 3.3V, so the same BOM line can serve a 1.8V-core MCU or a 3.3V peripheral bus without a separate voltage translator. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1001BI2-040.0000 MEMS Oscillator – 40 MHz, AEC-Q100","metaDescription":"Microchip DSC1001BI2-040.0000: 40 MHz XO (Standard), CMOS, AEC-Q100, -40°C to 85°C, 4-SMD No Lead.

The MEMS construction offers better shock and vibration tolerance, faster start-up, and a wider supply voltage range (1.8V to 3.3V) compared to many quartz oscillators that are tied to a single supply.
