Product details

The DSC1001CI2-019.6608B is a MEMS-based XO (Standard) oscillator delivering a 19.6608 MHz CMOS output with ±25 ppm frequency stability.

Operates from 1.8V to 3.3V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator — one BOM line serves multiple voltage domains.

Housed in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — standard footprint for MEMS oscillators, reworkable with hot air if you keep the nozzle off the plastic lid.

No pin-compatible second source confirmed, but the DSC1001 series includes multiple frequencies in the same footprint if the clock tree changes.

Frequently asked questions

Is the DSC1001CI2-019.6608B AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, making it suitable for automotive applications where reliability screening is required.

What does the standby function do on this oscillator?

The standby (power-down) function disables the output and reduces supply current to 15 µA max, useful for battery-powered or sleep-mode designs.

Can the DSC1001CI2-019.6608B replace a standard quartz crystal oscillator?

Yes — it is a drop-in MEMS replacement for a 19.6608 MHz quartz XO with CMOS output. The MEMS resonator is more resistant to vibration and shock than a quartz crystal, which matters in automotive and industrial environments.
