Product details

Active production — AEC-Q100 qualified MEMS oscillator

Supply voltage and standby — power budget fit

Operating from 1.8V to 3.3V, the DSC1001AI1-001.0000 covers the three most common digital supply rails without needing a separate regulator. Maximum supply current is 6.5 mA, making it a low-power clock source for always-on domains.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The exposed pad provides a thermal and electrical connection to the ground plane — the PCB layout should include a matching pad with vias to the inner ground layer for heat sinking and noise shielding. Surface-mount mounting is standard for reflow assembly; the 4-pin footprint is compatible with common pick-and-place equipment. No special handling beyond standard MSL precautions is required.

Frequently asked questions

Does the DSC1001AI1-001.0000 have a standby function?

Yes, the DSC1001AI1-001.0000 includes a Standby (Power Down) function. When the standby pin is asserted, the output goes to high-impedance and the internal oscillator circuitry is disabled, reducing supply current to near-zero. This is useful for battery-powered or intermittently operated systems.
