Product details

22.5792 MHz MEMS XO with ±10 ppm stability

The DSC1001AE5-022.5792T is a MEMS-based XO (Standard) oscillator delivering a 22.5792 MHz CMOS output with ±10 ppm frequency stability — tight enough for precision clocking in audio, video, and serial-data applications where a few ppm of jitter can push the bit-error rate past the link budget. It operates from a 1.8V to 3.3V supply, so a single BOM line covers 1.8V and 3.3V logic domains without a level translator on the clock output.

The MEMS resonator construction eliminates the quartz-crystal cold-start and aging drift that can cause a quartz oscillator to fail ppm after 10 years. The laser-etched date code and package marking should trace cleanly back to Microchip's assembly lot for provenance verification.

Frequently asked questions

Can DSC1001AE5-022.5792T replace a quartz crystal oscillator?

Yes — it is a drop-in MEMS XO that outputs a CMOS clock signal at 22.5792 MHz with ±10 ppm stability, so it directly replaces a quartz-based oscillator of the same frequency and output type. The MEMS base resonator eliminates the quartz crystal's aging drift and mechanical shock sensitivity, which is why Microchip qualifies it to AEC-Q100 for automotive use. No board-level changes are needed if the existing oscillator is a 4-pin 7.0×5.0 mm SMD package with the same pinout.
