Product details

48 MHz MEMS oscillator with automotive qualification

The DSC1001DL5-048.0000T is an active-production MEMS-based XO (standard oscillator) delivering a 48 MHz CMOS output across a 1.8 V to 3.3 V supply range — one part number covers the common logic rails without a separate voltage variant.

Standby power-down for battery-aware designs

Active draw is 7.2 mA max at 48 MHz, so the wake-to-run current step is under 7.2 mA; the supply decoupling cap on the Vdd pin must handle this transient without a voltage dip that could trip the brown-out detector.

A buyer filling a BOM line for a multi-year automotive program can commit without stockpiling against a discontinuation window.

Frequently asked questions

What is the exact frequency and supply voltage of DSC1001DL5-048.0000T?

48 MHz with a supply range of 1.8 V to 3.3 V. The same order code covers all three common logic rails — no need to select a voltage-suffix variant.

Is DSC1001DL5-048.0000T qualified for automotive applications (AEC-Q100)?

Yes — it carries AEC-Q100 qualification and operates from -40°C to +105°C, covering the under-hood temperature grade with margin.

Does DSC1001DL5-048.0000T have a standby (power down) function and how does it work?

Yes — the standby (power down) function reduces supply current to 15 µA max. The output goes high-impedance in standby; a logic-low on the enable pin (typically pin 1 on the 4-pin package) triggers the power-down state.

Can I replace a quartz 48 MHz oscillator with DSC1001DL5-048.0000T?

Functionally yes — both deliver a 48 MHz CMOS clock. The MEMS base resonator means no quartz crystal aging drift, and the ±10 ppm frequency stability matches or beats many quartz XOs. The 4-SMD no-lead footprint is the same 2.5 mm x 2.0 mm land pattern used by standard quartz oscillators — confirm the enable-pin logic polarity against the quartz part's pin 1 function before swapping.
