Product details

Automotive-grade MEMS clock for precision serial buses

No external load caps or feedback resistor are needed; the output is a rail-to-rail CMOS signal that drives a single logic load directly.

Wide supply range and power-down for mixed-voltage designs

A single BOM line serves a 1.8V FPGA bank and a 3.3V microcontroller on the same board — no level translation or second oscillator needed. 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.

Frequently asked questions

How can I order DSC1001CI2-018.4320 or check current availability?

Submit an RFQ through this page. The part is Active and in production; we source it through independent distribution and confirm availability and pricing at quote time. No stock-holding claim is made — every order is confirmed against the BOM quantity before commitment.

Is DSC1001CI2-018.4320 AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating.

Can this MEMS oscillator replace a standard quartz oscillator in an existing design?

The DSC1001CI2-018.4320 is pin-compatible with standard 3.2 x 2.5 mm quartz oscillators of the same frequency and output type. The key differences are: no external load capacitors needed, faster start-up, and better vibration immunity. Verify the supply voltage range (1.8V to 3.3V) and enable polarity match the original part before substitution.
