Product details

MEMS XO at 66.666 MHz with CMOS output

The DSC1001CI2-066.6660T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 66.666 MHz CMOS output.

Automotive-grade qualification and supply range

AEC-Q100 qualified — this is the automotive IC stress and reliability standard. The part is tested for temperature cycling, ESD, and latch-up per the AEC-Q100 flow, making it eligible for under-hood and chassis-domain applications that require PPAP documentation.

Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.126" x 0.098" footprint is a common 3.2 x 2.5 mm oscillator land pattern — layout guidelines from the DSC1001 datasheet apply.

Frequently asked questions

Does DSC1001CI2-066.6660T have a standby function?

Yes, the standby (power-down) function is built in. When the standby pin is pulled low, the output is disabled and supply current drops to 15 µA max. This allows the system to gate the clock without an external MOSFET.

Is DSC1001CI2-066.6660T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification. This means it has passed the automotive-grade stress tests (temperature cycling, ESD, latch-up) and is suitable for automotive applications requiring PPAP.
