Product details

16.384 MHz MEMS oscillator with ±10 ppm stability

The DSC1001AL5-016.3840 is a standard XO (Standard) type oscillator built on a MEMS resonator, outputting a 16.384 MHz CMOS clock signal. Supply voltage spans 1.8V to 3.3V, covering the common digital core and I/O rails without an external regulator. The standby (power down) function drops supply current to 15 µA max, letting the system sleep the oscillator when the bus is idle.

AEC-Q100 qualification and temperature range

Rated AEC-Q100, this oscillator is qualified for automotive-grade reliability — temperature cycling, ESD, and latch-up tested per the AEC-Q100 stress regime. Lifecycle status is Active, meaning Microchip still produces this part and it is available for new designs.

Housed in a 4-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. The exposed pad should be soldered to a ground-plane thermal land on the PCB — this pulls heat from the MEMS die and stabilises the frequency against local hot spots from adjacent regulators or processors. Surface-mount mounting type means standard reflow profiles apply; the no-lead pad layout matches the common 7x5 mm oscillator footprint used across the DSC1001 family.

Frequently asked questions

Is DSC1001AL5-016.3840 AEC-Q100 qualified?

Yes, the part carries an AEC-Q100 rating, meaning it passed automotive-grade qualification tests for temperature, reliability, and ESD. It is suitable for deployment in automotive electronics where the AEC-Q100 certification is required by the tier-1 or OEM specification.

What is the difference between DSC1001AL5-016.3840 and DSC1001AL2-016.3840?

Both are 16.384 MHz MEMS XOs in the DSC1001 family. The difference is in the frequency stability grade and temperature range — the AL5 suffix indicates ±10 ppm stability over -40°C to 105°C, while the AL2 suffix typically specifies a wider stability or different temperature range. Confirm the exact AL2 variant's datasheet for the specific stability and temperature rating before substituting.

Can DSC1001AL5-016.3840 replace a standard quartz crystal oscillator?

Yes — this is a drop-in MEMS-based XO that outputs a CMOS-level clock directly, so it replaces a quartz crystal oscillator module in the same 7x5 mm footprint and supply voltage range. The MEMS resonator is less sensitive to vibration and shock than a quartz crystal, which can be an advantage in automotive or industrial environments. Ensure the load capacitance and drive level are matched per the oscillator's datasheet; the MEMS XO has its own internal PLL and does not require external load capacitors.
