Product details

75 MHz fixed-frequency XO with AEC-Q100 qualification

It delivers a CMOS output and includes an Enable/Disable function for power savings in the system. The AEC-Q100 qualification confirms it meets automotive reliability stress and PPAP requirements—relevant for under-hood or cabin electronics.

Supply range and package fit

The supply voltage spans 2.25V to 3.6V, covering both 2.5V and 3.3V rails without an external LDO. Housed in a 6-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Is the DSC1121DI1-075.0000 compatible with a 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec. No external regulator is needed.

Does the DSC1121DI1-075.0000 have an enable/disable pin?

Yes, the function is Enable/Disable. When disabled, the maximum supply current drops to 22 mA, allowing power gating in the system.

Is the DSC1121DI1-075.0000 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade reliability stress tests and is suitable for automotive applications.
