Abracon ASxKDV Continuous Voltage SMD Clock Oscillators

Abracon ASxKDV Continuous Voltage SMD Clock Oscillators are low-power optimized quartz-based 32.768kHz crystals. These standard clock oscillators offer an extremely low supply current, a 1.62V to 3.63V voltage range, and a -40°C to +85°C operating temperature range. The ASxKDV oscillators can be used across multiple sockets utilizing the same frequency which removes the dependency of an LDO to regulate the supply voltage. The Abracon ASxKDV Continuous Voltage SMD Clock Oscillators free up board space for other key components and extends the battery life. Ideal applications include portable and wearable devices, Internet of Things (IoT), consumer electronics, industrial control and automation, and mobile communications.
