The SG-3031CM and SG-3031CMA are industry-leading 32.768kHz crystal oscillators offering low power consumption, a wide operating temperature range, and automotive compliance. These oscillators feature a built-in crystal unit for adjustment-free operation and utilize CMOS ICs to reduce current draw. The VIO pin allows for control of the output swing amplitude. The SG-3031CMA is AEC-Q100 compliant.
