Product details

The DSC1001AE1-016.6667T is a Microchip MEMS-based XO (Standard) oscillator delivering a 16.6667 MHz CMOS output with ±50ppm frequency stability across its -20°C to 70°C operating range.

No external load capacitors are needed — the MEMS oscillator integrates the resonator and load circuitry, so the BOM saves two passives compared to a quartz crystal + load cap pair.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — the standard 7050 footprint that matches most quartz oscillator pads, so a board designed for a quartz can of the same frequency often accepts this MEMS part without a layout change.

Frequently asked questions

Is DSC1001AE1-016.6667T a direct replacement for a standard quartz oscillator of the same frequency?

Yes, in most cases. The 7.00mm x 5.00mm 4-SMD footprint matches the common 7050 quartz oscillator footprint, and the CMOS output is the same logic level. The MEMS resonator eliminates the need for external load capacitors and offers better vibration resistance and long-term stability than quartz, but the electrical interface is the same.

What is the frequency stability of DSC1001AE1-016.6667T?

±50ppm over the -20°C to 70°C operating range. This is the total frequency deviation including temperature, supply voltage, and aging effects — tight enough for most MCU clock trees, CAN controllers, and USB interfaces without external trimming.

Does DSC1001AE1-016.6667T require external load capacitors?

No. Because the resonator is a MEMS device integrated with the oscillator circuitry, the part does not need the two external load capacitors that a quartz crystal would require. This saves two passives per BOM position.
