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. ## Active production status and sourcing posture The package is supplied in Tube; reel quantities are available through the same ordering channel.

The MEMS resonator also withstands the shock and vibration levels typical of engine compartments and chassis-mounted modules."},{"question":"How does the DSC1001 series compare to the DSC1002 series?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI2-049.1520","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI2-049.1520 when reusing this data.
