As digital timing devices, Programmable Timers and Oscillators are applicable to a wide range of applications, including power management, communications and industrial systems. 8N3DV85EC-0169CDI devices are especially used to generate precise timing signals.

These devices are programmed with a reprogrammable configuration register. This allows users to select different output clock frequencies and signals, such as single-ended (LVPECL, LVDS, or LVCMOS) differential (CML, LVDS, or PECL) and HCSL for reference clock.

Working Principle

8N3DV85EC-0169CDI devices work by generating a string of pulses which are divided by a predetermined division ratio. The division ratio is preset by the configuration registers. The division ratio and output clock frequency are programmed via I2C interface.

The division ratio is determined by a programmable prescaler, pre- and post-scalers and also the clock source. The CML or LVDS output can generate a wide range of frequencies, with the precision of output frequency depending on the setting of the division ratio. The output clock frequency can be reduced to as low as 1Hz and increased up to 65MHz.

The device also includes an offset register. This allows the users to set an offset voltage to the VCO. This offset voltage is used to compensate for the process variations of the VCO and improve the accuracy of the output frequency. This has the additional benefit of reducing the amount of jitter in the output clock frequency.

8N3DV85EC-0169CDI devices also have an external reference clock input. This input can be used to adjust the frequency of the output clock relative to the external reference clock. This feature is especially useful in applications where a stable and precise frequency is required.

Finally, 8N3DV85EC-0169CDI devices have a power-down mode. This allows these devices to be powered down when not in use, thus reducing power consumption. The power-down mode can be programmed via the configuration registers.

Overall, 8N3DV85EC-0169CDI devices are useful for generating accurate and stable timing signals. They are designed for high precision applications and are suitable for a wide range of applications.
