The standby (power-down) function drops supply current to 15 µA max — useful for modules that sleep between CAN wake-up cycles without a separate load-switch for the oscillator. ## Supply range, frequency stability, and standby current Operates from 1.8 V to 3.3 V, covering the common 1.8 V, 2.5 V, and 3.3 V logic rails without a voltage translator on the oscillator supply. The absolute pull range is ±20 ppm, which sets the frequency accuracy across voltage and temperature — enough for a UART baud clock or a CAN controller time base. Active supply current is 8 mA max; in standby the oscillator draws 15 µA max, preserving battery in always-powered automotive modules that spend most of their life asleep. ## Package and mounting — 4-VDFN, 3.20 mm x 2.50 mm Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The surface-mount footprint is compact enough for space-constrained ECU and sensor PCBs; the 0.90 mm height clears most enclosure standoffs. ## Active lifecycle — quoted to order Supplied in Tape & Reel (TR) — store the reels dry; the 4-VDFN package is not moisture-sensitive by default, but standard MSL handling applies. Quoted to order against the BOM quantity; availability confirmed at RFQ.","metaTitle":"DSC1001CI3-003.5790T Microchip MEMS XO 3.579 MHz CMOS","metaDescription":"Microchip DSC1001CI3-003.5790T MEMS oscillator: 3.579 MHz, CMOS output, 1.8-3.3 V supply, AEC-Q100, -40 to 85°C, standby function.
