Programmable timers and oscillators play a vital role in the efficient functioning of numerous industrial and home appliances, often managing the amount of time needed for certain processes, activating different mechanisms in energy-saving devices, regulating the operation of sensors, and providing accurate time synchronization for both personnel and electronic devices. 8N3SV75LC-0170CDI8 is a type of timer that comes with configurable clock output, power down detection and power fail detection, making it suitable for a number of clock/timing applications. This article delves into its application field and working principle.

Applications

The 8N3SV75LC-0170CDI8 is mainly used in alarm clocks, consumer electronics, and household appliances such as washing machines and refrigerators. It is particularly useful in the manufacturing industry, providing accurate time synchronization in large-scale industrial processes such as food production, material handling, and robotics. In addition, this timer is used for utility metering, HVAC systems, and embedded applications.

Operating Principle

The 8N3SV75LC-0170CDI8 has a quartz crystal oscillator at its core, the output and accuracy of which determines the accuracy of the timer itself. The quartz crystal oscillator produces a high-frequency alternating current, which is pooled by an amplifier and voltage-controlled oscillator. The frequency of the alternating current is determined by the capacitance of the quartz crystal and can reach frequencies up to 200MHz. The AC signal is then passed through a divider circuit which divides it into smaller signals, which in turn are sent to the oscillator, providing a stable, visible output to meet the timer\'s specific function.

Configuration Features

The 8N3SV75LC-0170CDI8 includes options for pulse mode distribution, automatically detected output divider configuration, and drill-down traceability for custom clock configuration. It also comes with both a 64-pin VQFPN package and a 56-pin QFN package with a heat spreader for improved thermal performance. The QFN package includes extra ground pins for mounting options, making it a more desirable choice for applications requiring higher current.

Power Fail Detection and Power Down Detection

The 8N3SV75LC-0170CDI8 has failsafe features to maintain its accuracy in the event of a power failure or device shutdown. If the device is running and there is a loss of power, it detects the power failure instantly and sends out a signal to the reference clock. This ensures that the device will not be impacted and will retain its accuracy when power is renewed. Similarly, if the device is in sleep mode and there is a power down, the timer will detect it and switch to a low power mode until power is restored, preserving its accuracy.

Overall Benefits

The 8N3SV75LC-0170CDI8 is a reliable and affordable programmable timer that can be used in a wide range of applications. With its quartz crystal oscillator and multiple package options, this timer provides increased accuracy and reliable power fail detection and power down detection. This makes it an ideal choice for projects that require precision and higher current.
