Product details

Active MEMS oscillator at 131.072 MHz

The DSC1001AE1-131.0720 is an active-production MEMS-based XO from Microchip, delivering a 131.072 MHz CMOS clock with ±50 ppm frequency stability across the full -20°C to 70°C operating range.

Supply voltage tolerance and standby function

The supply voltage range spans 1.8V to 3.3V, meaning a single BOM line can serve 1.8V, 2.5V, and 3.3V clock domains without a separate voltage regulator — just tie the Vdd pin to the rail.

Housed in a 7.00 mm × 5.00 mm 4-SMD no-lead exposed pad package, 0.90 mm seated height — the exposed pad provides a low-thermal-resistance path to the PCB ground plane, which helps keep the MEMS die temperature stable under airflow changes.

Frequently asked questions

Is the DSC1001AE1-131.0720 compatible with a 1.8V supply?

Yes — the supply voltage range is 1.8V to 3.3V, so it operates directly on a 1.8V rail without an external regulator.

What is the standby (power down) function on this oscillator?

The standby function disables the output and reduces supply current to 15 µA max. The oscillator resumes normal operation when the standby pin is de-asserted — no start-up delay penalty beyond the typical MEMS oscillator wake time.

Can the DSC1001AE1-131.0720 replace a quartz 131.072 MHz oscillator?

Yes, if the quartz oscillator has a CMOS output and operates within the same 1.8V–3.3V supply range. The MEMS version offers better shock and vibration immunity and a ±50 ppm stability spec that matches many quartz XOs. Confirm the footprint — the 7.00 mm × 5.00 mm 4-SMD package is a common size but verify pad layout against the quartz part's footprint.
