Product details

The DSC1001DL2-048.0000 is an AEC-Q100 qualified MEMS XO delivering a 48 MHz CMOS clock from a single 1.8–3.3 V supply. The -40 to +105 °C operating range covers under-hood and outdoor telecom enclosures without an external heater or fan.

The 1.8–3.3 V supply range means the same BOM line serves a 1.8 V core rail or a 3.3 V I/O rail; no level translator needed between the oscillator output and the downstream CMOS input.

Small footprint and layout considerations

Housed in a 2.50 mm × 2.00 mm 4-SMD no-lead package, the DSC1001DL2-048.0000 fits the same land pattern as standard 2.5×2.0 mm crystal oscillators. The 0.90 mm seated height clears low-profile enclosures. Because the package has no leads, the PCB footprint relies on the solder-paste stencil aperture to control standoff — a 0.125 mm stencil thickness with a 1:1 pad-to-aperture ratio is a typical starting point for reflow.

The DSC1001 series is Microchip's current MEMS oscillator family, so replacement risk is low for a design starting today.

Frequently asked questions

Is the DSC1001DL2-048.0000 automotive qualified?

Yes, it carries an AEC-Q100 rating, which covers the -40 to +105 °C temperature grade and the reliability stress tests required for automotive ICs. This qualifies it for under-hood and cabin-mounted electronics.

What supply voltage does the DSC1001DL2-048.0000 accept?

The CMOS output swings rail-to-rail, so the logic levels match the supply voltage without external translation.

Does the DSC1001DL2-048.0000 have a standby function?

Yes. The part includes a standby (power down) pin that reduces supply current to 15 µA max when the oscillator is disabled. This is useful for battery-powered designs that need to cut clock power during sleep.

What is the output type of the DSC1001DL2-048.0000?

CMOS. The output is a rail-to-rail square wave compatible with standard digital logic inputs. No external termination or level shifting is needed for typical MCU, FPGA, or SoC clock inputs.

Where can I buy the DSC1001DL2-048.0000?

Available through independent distribution channels.
