The standby (power-down) function drops the current draw to 1 µA typical — useful for battery-backed systems that need to disable the clock between active intervals without removing power. ## Package and board-fit note Housed in a 4-VDFN with exposed pad, 7.00 mm x 5.00 mm footprint, seated height 0.90 mm max. Listed as Active by Microchip. Quoted to order against BOM quantities through independent distribution — availability confirmed at RFQ time.","metaTitle":"DSC1505AI3A-66M66670 MEMS XO – 66.6667 MHz, LVCMOS, ±20 ppm","metaDescription":"Microchip DSC1505AI3A-66M66670: 66.6667 MHz MEMS oscillator, LVCMOS output, ±20 ppm stability, 1.8V supply, standby power-down, -40°C to 85°C.
