The MEMS resonator replaces a quartz crystal, which means the part is inherently more resistant to vibration and shock than a traditional crystal oscillator — a practical advantage in motor-drive or transportation applications where board-level mechanical stress can pull a quartz fundamental off frequency. Sourced through independent distribution; quoted to order against the BOM quantity. The 4-VDFN exposed-pad package (7.00 mm x 5.00 mm footprint, 0.90 mm seated height) is a standard MEMS oscillator land pattern. ## Standby function and supply current profile The Standby (Power Down) function drops the supply current to 1 µA typical when the enable pin is de-asserted. For a system that spends most of its time in a low-power sleep state and wakes periodically to transmit or log data, this standby current is below the leakage floor of most battery-backed RTCs — the oscillator does not add a meaningful drain to the sleep budget. Active supply current is 7.5 mA max at 66.6667 MHz — a reasonable figure for a MEMS oscillator at this frequency and supply voltage. The 1.8V rail keeps dynamic power lower than a 3.3V equivalent, which matters when the oscillator shares a regulator with other 1.8V logic.","metaTitle":"DSC1505AI3A-66M66670T MEMS Oscillator 66.6667 MHz 1.8V","metaDescription":"Microchip DSC1505AI3A-66M66670T XO (Standard) MEMS oscillator, 66.6667 MHz, ±20 ppm stability, 1.8V supply, LVCMOS output, -40°C to 85°C.
