8N3DV85LC-0114CDI is a small size, low power consumption clock/timing programmable timer and oscillator which operates on 3.2 to 5.5V voltage range. It is capable of providing programmable clock/timing solution with excellent performance, low jitter and low power consumption.

The 8N3DV85LC-0114CDI application field includes industrial, automotive, consumer and medical markets. It is especially suitable for the applications require high accuracy and programmability. It can be applied in touchscreens, coding, switch-mode power supplies, radio frequency, telecommunications and networking, equalizers and filters.

The 8N3DV85LC-0114CDI is designed based on high performance CMOS technology. It is highly integrated and provides three programmable ring oscillators with adjustable frequency, resolution, andduty cycle control, a 16-bit prescaler, and two digital programmable delay blocks. The chip also provides a built-in temperature sensor to allows precise delay setting which can adapt to different ambient temperatures.

The working principle of the 8N3DV85LC-0114CDI mainly depends on the delayed-lock loop (DLL) and the delay-locked loop (DLL). The delays in the DLL will be recognized accurately and stably without relying on external components. The working frequency can be adjusted according to the expected programming value. The tENTX is used to compare the frequency with the TimeChip ground output value, while the reference clock frequency is kept constant. The output frequency is then tuned accordingly. The aim of the on-chip temperature sensor is to provide stable output frequency over fluctuating temperature ranges. The chip provides a 16-bit prescaler, enabling the output frequency to be divided by up to 65535 more precisely.

The 8N3DV85LC-0114CDI includes an internal VCO, which helps to generate a wide range of frequencies from 0.12kHz to 200MHz. The internal VCO setting is based on external values and allows a programming range of Vlotage-controlled Oscillator (VCO) range and reference frequency. An internal divider is used to divide both the low and high frequency bands, allowing the user flexibility to configure the output frequency. This allows the chip to be fine-tuned in response to changing conditions, results in an efficient frequency usage rate and enables higher performance levels than other traditional analog approaches.

Overall, the 8N3DV85LC-0114CDI is a high performance, programmable and efficient Clock/Timing programmable timer and oscillator. It is especially suitable for the applications require high accuracy and programmability, such as touchscreens, coding, switch-mode power supplies, radio frequency, telecommunications and networking, equalizers and filters. It offers excellent performance, low jitter and low power consumption.
