The IDT5V9885NLGI8 is a high-performance, low-cost clock and timing solution designed specifically for synchronous application applications. It is one of the most popular products from the IDT Clock / Timing portfolio and offers a wide range of features such as digital and analog output, programmable output frequency, and wide operating temperature range.

The IDT5V9885NLGI8 is primarily used in synchronous applications such as memory, processor, bus and interface systems as well as other applications requiring a high degree of accuracy. It is ideal for high-speed systems where selectable output frequency and wide operating temperature range is required.

The IDT5V9885NLGI8 includes two integrated circuits, the PLL (phase-locked loop) and VCO (voltage-controlled oscillator). The PLL is used to lock the input and output frequencies and the VCO is used to generate the desired clock frequency. Together, they form a highly accurate clock and timing system. The PLL is programmed using an external crystal oscillator and the resulting oscillator frequency is then multiplied using the VCO and a programmable frequency divider/multiplier to generate the desired output clock frequency.

The PLL also includes a frequency divider circuit to adjust the output frequency depending on the required application and operating conditions. This frequency divider circuit is digitally configurable and provides excellent clock stability and accuracy for a variety of applications. In addition, the frequency divider circuit includes a low-frequency cutoff circuit and a high-frequency cutoff circuit to enhance the accuracy of the clock frequency output.

The VCO also includes a digitally configurable voltage-controlled oscillator that adjusts the clock frequency according to the application and operating conditions. This allows the output clock frequency to remain stable over a wide temperature range and with varying input clock frequency. The VCO also includes an integrated timer that can be used to generate programmable output pulse widths or delays.

The IDT5V9885NLGI8 also includes a highly configurable power management circuit that efficiently manages the power supply to the VCO and PLL circuitry. This power management circuit features dynamic tuning and provides multiple power supply voltages and current levels to efficiently power the IC. This power management circuit also provides low-power operating modes to further reduce power consumption.

The IDT5V9885NLGI8 provides a wide range of features making it ideal for synchronous applications. It is a highly accurate, low-cost clock and timing solution for a variety of applications. The integrated phase-locked loop and voltage-controlled oscillator along with the configurable power management circuitry provide exceptional accuracy and power efficiency for high-speed systems.
