Active current draw is 8 mA max; when the Standby (Power Down) function is asserted, supply current drops to 15 µA max — useful for battery-backed or sleep-mode subsystems where the clock tree must be gated without a discrete load switch. ## Package footprint and board integration Housed in a 4-SMD, No Lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — the compact footprint fits tight timing-tree layouts on multi-layer automotive PCBs, though the no-lead construction means the solder joints are hidden under the package and require X-ray inspection for voiding.","metaTitle":"DSC1004DI5-066.5800 MEMS XO 66.58 MHz AEC-Q100","metaDescription":"DSC1004DI5-066.5800: Microchip MEMS XO, 66.58 MHz, CMOS output, AEC-Q100, ±10 ppm stability, 1.8-3.3V, -40°C to 85°C.
