For a battery-backed ECU that sleeps between ignition cycles, this keeps the quiescent draw below the module's self-discharge target. Maximum active current is 6.3 mA at 18.432 MHz — well within the budget of a 100 mA LDO feeding the oscillator and its load. ## Package, footprint, and layout note Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.126\" x 0.098\" footprint matches the industry-standard 3.2 x 2.5 mm oscillator land pattern — a drop-in replacement for quartz XOs of the same size, provided the supply voltage and enable polarity are verified. The four pads are the standard oscillator pinout: enable, ground, output, and supply. ## Active production status and sourcing posture No minimum order threshold beyond standard reel or tube multiples; the package is supplied in Tube per the listing.","metaTitle":"DSC1001CI2-018.4320 MEMS XO – AEC-Q100, 18.432 MHz, CMOS","metaDescription":"Microchip DSC1001CI2-018.4320 – active XO, MEMS resonator, 18.432 MHz CMOS output, ±25 ppm, AEC-Q100, -40°C to 85°C.
