The IDT5T2010NLGI is a high-performance intelligent digital timing circuit that eliminates the need for an external controller, providing users with a more efficient, cost-effective timing package. The IDT5T2010NLGI is a clock generator, phase lock loop (PLL), and frequency synthesizer, all in one package. It is capable of generating a wide range of frequencies across multiple outputs and has a high output accuracy with minimal jitter.

Application Field

The IDT5T2010NLGI is ideal for use in clock and timing circuits such as frequency converters, DRAM/SRAM controllers, system timing references, and other frequency-critical applications. It is designed to operate in both high-frequency and low-power applications within the range of 1-200 MHz. The IDT5T2010NLGI can also be used in wireless systems, Ethernet networks, and other communications-related products.

Working Principle

The IDT5T2010NLGI uses a phase-locked loop (PLL) system for frequency-synthesis that enables two distinct clock outputs, each of which can be independently configured. The PLL consists of a voltage-controlled oscillator (VCO), a frequency divider (divider), and a phase detector. The VCO is designed to produce a wide-range of frequencies across multiple outputs, while the phase detector ensures that the clock output and reference input signals remain in-phase. An external divider or divider-counter is then used to generate the desired clock outputs. Furthermore, the IDT5T2010NLGI features an adjustable phase detector, allowing for further fine-tuning of the clock output signals.

In addition to these features, the IDT5T2010NLGI also includes on-chip EMI and jitter suppression circuitry, which ensure that the clock outputs adhere to strict standards of stability and noise immunity. This reduces power consumption and increases the accuracy of the clock signals. The IDT5T2010NLGI also features an adjustable current-mode logic (CML) output for high-speed clock synchronization with external devices.

Conclusion

The IDT5T2010NLGI is a high-performance, cost-effective solution for use in clock and timing circuits. It allows users to generate a wide range of frequencies across different outputs, all while maintaining high accuracy and minimum jitter. Furthermore, it features on-chip EMI and jitter suppression, as well as a CML output for high-speed clock synchronization. This makes it an ideal choice for use in wireless systems, Ethernet networks, frequency converters, DRAM/SRAM controllers, and other frequency-critical applications.
