Programmable timers and oscillators are components used across a wide range of applications including radio, satellites, industrial controls and consumer electronics. The 8N4QV01KG-0128CDI8 is one such device, combining multiple timer and oscillator functionalities into a single versatile component. This article will look at the various applications of this versatile device and the operational principles that define its different functionalities.

Applications

The 8N4QV01KG-0128CDI8 is a programmable timer/oscillator versatile solution providing three separate modes of operation – timer, clocking, and oscillator – each with their own set of features and applications. As a timer, the device is well suited for automotive applications, monitoring and controlling vehicle functions, such as airbags deployment and other safety-critical devices. It is also frequently used for real-time, mission-critical applications, such as aircraft and missile stabilization and guidance systems.

The 8N4QV01KG-0128CDI8 is capable of operating in two clocking modes. The first mode is an asynchronous clocking mode, which is commonly employed in signal conditioning applications. This mode allows the device to transfer data from two separately oscillating clock domains, for example from a digital signal processor (DSP) and a microcontroller (MCU). The device\'s second clocking mode, synchronous mode, can be utilized in components such as a data communications controller, which require data to be accurately maintained and transferred between a number of connected systems.

As an oscillator, the 8N4QV01KG-0128CDI8 can be used to generate a variety of waveforms of precise frequencies and amplitudes. This makes it particularly suitable for a broad range of test and measurement applications, ranging from precise frequency selection used in telecommunications, to signal integrity applications in medical imaging systems. Finally, its programmable features and rich peripherals enable a broad range of applications within the industrial automation, process control and factory automation markets.

Working Principle

The 8N4QV01KG-0128CDI8 is programmed using digital and analog configuration signals. These signals are used to configure the operation of the timer, clocking, and oscillator modes. At the core of the device are two independent oscillators with individually adjustable timing generator (ITG) blocks. These oscillators and ITG blocks allow for precise tuning of the frequency and duty cycle of the timer and clock outputs. By adjusting the pre-scaler, the user can achieve very precise frequencies, as low as 10 Hz or as high as 400MHz.

In timer mode, the user only needs to program the pre-scaler and the reference clock, and the device will generate a single-pulse or linearly increasing or decreasing pulse sequence of precise frequency and duty cycle. In clocking mode, the device can be configured to separate asynchronous clock domains or to generate a continuous stream of clock pulses with precise frequency and duty cycle. In oscillator mode, the device can generate single or repetitive waveforms of precise frequency, amplitude and duty cycle.

The 8N4QV01KG-0128CDI8 also offers an advanced power management system, allowing for adjustment of operating voltage, current and power levels. This power management system helps the device to efficiently consume power by scaling down the voltage and current draw when in idle mode. Additionally, the device provides two separate power supply pins that can be used to drive separate digital and analog signal paths.

Conclusion

The 8N4QV01KG-0128CDI8 is an incredibly versatile programmable timer and oscillator for a range of applications in automotive, telecommunications, signal integrity in medical imaging systems and industrial automation. It offers three distinct modes of operation – timer, clocking, and oscillator – and is driven by independently adjustable oscillators and ITG blocks. Extended features like adjustable power management and multiple supply pins make this device a great solution for many of today’s innovative applications.
