Programmable timers and oscillators are widely used in a variety of applications, ranging from consumer electronics and communications to medical, industrial and automotive applications. In this article, we will discuss the 8N3DV85KC-0126CDI programmable timer and oscillator and the application field it is suitable for, as well as how it works.

Application Field

The 8N3DV85KC-0126CDI timer and oscillator is a high-precision real-time clock device suitable for frequency synthesis applications. It provides very precise frequency control and is well suited for applications in telecommunications, wireless, automotive and industrial systems. It can also be used for precise time base synchronization and frequency measurement.

Its high-precision output frequency ranges between 0.01Hz to 8MHz, which makes it ideal for numerous applications, such as time base counter, frequency measurement, data acquisition and timing applications. With its reliability and accuracy, it is a suitable device for many computing systems and applications.

Working Principle

The 8N3DV85KC-0126CDI timer and oscillator uses a crystal oscillator and frequency synthesis technology to generate precise output frequencies. The device is programmed by its on-chip RISC processor, the ISE2118A. This processor has a memory of 16kHz and is powered by a 1.8V power supply. The frequency is accurately controlled by setting a divider ratio value from 0 to 2.2k. This is then used to generate an accurate output frequency.

The device uses a Voltage-Controlled Oscillator (VCO) module to provide frequency control and high accuracy. The VCO is divided into two sections, the high-gain oscillator and the low-gain oscillator, both of which are powered by 0.3V and 1.8V power supplies respectively. The high-gain oscillator provides the high frequency stability and the low-gain oscillator provides the low frequency stability.

The 8N3DV85KC-0126CDI timer and oscillator also has a programmable oscillator buffer that can be used to adjust the output frequency as required. The output frequency can be adjusted from 0.01Hz to 8MHz, making it suitable for a variety of frequency measurement and control applications.

The device also has an embedded RISC processor, the ISE2118A, that enables advanced programmability and simple integration. The processor can execute simple self-programs and allows users to update the device\'s parameters. This makes it easier for users to tailor the device’s performance to their application.

In summary, the 8N3DV85KC-0126CDI programmable timer and oscillator is a high-precision real-time clock device suitable for frequency synthesis applications. It is suitable for applications in telecommunications, wireless, automotive and industrial systems. It has an on-chip RISC processor with memory of 16kHz, a programmable oscillator buffer and a Voltage-Controlled Oscillator module that allow users to adjust the output frequency from 0.01Hz to 8MHz. This makes it an ideal solution for applications requiring precise frequency control and accurate response times.
