The 8N3DV85LC-0119CDI is a general-purpose programmable timer and oscillator device manufactured and marketed by Maxim Integrated, Inc. Designed to provide a highly accurate, low-cost solution for application in embedded systems and other fields, the 8N3DV85LC-0119CDI is built with a variety of features that make it a great fit for use in a range of application areas.

This device is composed of five individual channels, each capable of operating one or two timer/oscillator functions. It provides a wide variety of timing and oscillation modes suitable for measuring, counting, modulation/demodulation, signal generation and precise frequency control. In order to accommodate different application needs, the 8N3DV85LC-0119CDI supports two input and output signal lines for each channel, as well as common configurations for all five channels.

Application Fields

Whether providing timing, counting, pulse-width modulation, pulse-frequency modulation, signal generation, or other functions, this device can be found in a wide variety of application fields. Common areas of application for the 8N3DV85LC-0119CDI include automotive, industrial and home automation, telecommunications, power systems, and medical devices. In these applications, its precise timing and oscillator functions can provide critical performance when a system’s accuracy and reliability demand the use of a programmable timer/oscillator device.

Working Principle

At the heart of the 8N3DV85LC-0119CDI is a programmable counter, which is used to time the output signals and thus generate a highly accurate timing and oscillator output. By combining the counter with the programmable clock divider, the desired frequency and pulse widths can be generated. Additionally, the device provides versatile edge-delay settings that can be used to shift the timing of the output signals in order to ensure reliable operation in different applications.

The input and output of the device are connected to the counter via two single-ended channels or four active, differential channels, depending on the chosen configuration. The two single-ended channels are configured to accept signals from external sources or output signals for external use. The per-channel differential inputs are configured to accept standard LVDS signals.

The counter in this device can be used to time the output signals while the clock divider is used to adjust the frequency. This combined functionality allows the 8N3DV85LC-0119CDI to generate precise and accurate timing and oscillator outputs.
