Product details

The DSC1001CI3-048.0000T is a 48 MHz MEMS-based XO with CMOS output, rated AEC-Q100 for automotive applications. The ±20 ppm frequency stability holds across that band, which is tight enough for CAN, LIN, and most MCU clock trees without external trimming. Supply voltage spans 1.7V to 3.6V, so a single BOM line covers 1.8V, 2.5V, and 3.3V logic rails — useful for multi-voltage designs or last-minute rail changes without requalifying the oscillator.

Maximum supply current is 10.5 mA when active.

Package, footprint, and mounting

Housed in a 4-VDFN package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. Surface-mount, tape-and-reel delivery.

Frequently asked questions

Is DSC1001CI3-048.0000T AEC-Q100 qualified?

Yes. The part carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood and cabin applications within its –40°C to 85°C range.

Does this MEMS XO replace a standard quartz oscillator?

Functionally yes — it outputs a CMOS clock at 48 MHz with ±20 ppm stability, same as a quartz XO. The MEMS resonator eliminates quartz startup time and is more vibration-tolerant, but the pinout and footprint (4-VDFN) differ from common quartz packages. Confirm board layout compatibility before substitution.

What is the output type and supply range?

CMOS output. Supply voltage is 1.7V to 3.6V, covering 1.8V, 2.5V, and 3.3V logic rails without a level translator.
