Product details

The DSC1001CL5-007.3728: This is a 7.3728 MHz MEMS-based oscillator (XO) that outputs a CMOS-level clock from a 1.8V to 3.3V supply rail — a drop-in replacement for a quartz-based oscillator in designs where the MEMS die's shock and vibration tolerance buys reliability on the factory floor or in the engine bay. Rated -40 to +105 °C and AEC-Q100 qualified, it covers the under-hood temperature band without needing a separate industrial-grade part number.

Standby power-down for sleep-mode current budget

Active current is 8 mA max at the rated supply, so the part's contribution to the running power budget is predictable across the voltage range.

Listed as Active — Microchip continues to manufacture the DSC1001CL5-007.3728 for new and existing designs.

Frequently asked questions

Is the DSC1001CL5-007.3728 AEC-Q100 qualified?

Yes — it carries AEC-Q100 ratings, which means it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood and cabin electronics.

Does the DSC1001CL5-007.3728 have a power-down function?

Yes — the standby (power down) function disables the output and drops the supply current to 15 µA max, allowing the system to shut down the oscillator during low-power sleep modes.

Can the DSC1001CL5-007.3728 replace a standard quartz crystal oscillator?

Yes — it is a drop-in MEMS replacement for a quartz XO in the same 4-VDFN footprint. The CMOS output and 1.8V–3.3V supply range match common logic families. The MEMS die offers better shock and vibration tolerance than quartz.
