Product details

The 4-SMD, No Lead package measures 3.20mm x 2.50mm with a seated height of 0.90mm — a standard footprint that fits most high-density PCB layouts without requiring via-in-pad or special fan-out. That 15 µA standby figure is low enough to leave the oscillator powered continuously in a battery-backed module without draining the cell.

The DSC1001CI2-049.1520 operates from a single supply rail spanning 1.8V to 3.3V. One order code covers 1.8V, 2.5V, and 3.3V logic families — no need to stock separate voltage variants for different board revisions. If the trace is short and the fan-out is one load, the oscillator stays well within its current budget.

Frequently asked questions

Is the DSC1001CI2-049.1520 AEC-Q100 qualified and suitable for automotive designs?

Yes, the DSC1001CI2-049.1520 is rated AEC-Q100, which means it has passed the automotive-grade qualification tests for temperature, reliability, and ESD. The MEMS resonator also withstands the shock and vibration levels typical of engine compartments and chassis-mounted modules.

How does the DSC1001 series compare to the DSC1002 series?

The DSC1001 series is a standard-performance MEMS oscillator family. The DSC1002 series typically offers tighter frequency stability options (e.g., ±10 ppm vs ±25 ppm) and may include extended temperature ranges. For the DSC1001CI2-049.1520, the ±25 ppm stability is sufficient for most serial communication clocks (I2C, SPI, UART) and general-purpose timing. If your application requires tighter ppm for Ethernet or USB, the DSC1002 series is the next step up.
