Product details

The DSC1001CI2-019.2000T is an active-production MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 19.2 MHz CMOS clock output with ±25ppm frequency stability across -40 to 85°C.

Supply voltage range and power budget

Operates from a single 1.8V to 3.3V supply, covering the common 1.8V, 2.5V, and 3.3V logic rails without needing an external regulator.

Package, footprint, and sourcing posture

Housed in a 3.20 mm x 2.50 mm 4-SMD no-lead package (0.90 mm seated height), compatible with standard pick-and-place and reflow processes.

Frequently asked questions

Is DSC1001CI2-019.2000T suitable for automotive applications?

Yes — it carries an AEC-Q100 rating, which qualifies it for automotive-grade reliability requirements. AEC-Q100 also implies PPAP-level documentation is available from Microchip if your tier-1 customer requests it.

How does DSC1001CI2-019.2000T compare to a traditional quartz crystal oscillator?

The MEMS resonator eliminates quartz start-up time and aging drift. It also provides better shock and vibration tolerance — relevant for automotive and industrial environments. The CMOS output is directly compatible with standard digital clock inputs, and the ±25ppm stability meets most serial-communication timing requirements.
