The DS1091LU-66+ is a high-performance, low-cost clock generator and phase-locked loop (PLL) from Maxim Integrated. The device is designed to provide high frequency stability, low jitter, and fast lock times in a single-clock generator package. It is suitable for applications ranging from high-precision timing to network synchronization and clocking in a variety of embedded systems.

The DS1091LU-66+ consists of a clock generator and a phase-locked loop (PLL) circuit. The clock generator container is also able to receive and process an external reference clock signal. The internal oscillator and external clock inputs are blended together and filtered to create a synthetic clock signal which is then passed to the PLL circuit.

The PLL circuit then takes the synthetic clock signal and multiplies it by a factor, creating an advanced clock signal. This advanced clock signal is the one that is used for the actual timing application. It has very low frequency tolerance and can be adjusted according to the requirement of the application.

The clock generator on the DS1091LU-66+ has six outputs, each with an individual frequency adjustment range between 33KHz to 333MHz. These outputs can also be adjusted with independent duty cycle adjustment up to 25%, which helps to optimize the overall performance. This allows for a variety of different applications including industrial, medical, telecom and defense applications.

The DS1091LU-66+ uses the PLL circuit to ensure good synchronization between the clock generator and the external clock. The PLL uses a feedback loop to compare the output of the clock generator to the input of the oscillator and to adjust the multiplier inside the clock generator accordingly. This allows the clock to maintain very tight precision and low jitter over a wide range of frequencies.

The DS1091LU-66+ is a versatile and efficient clock generator and PLL that can be used for a variety of clock synchronization applications. With its wide frequency range, low jitter, and fast lock times, the device is ideal for applications such as synchronous digital systems, data communications, and clock synchronization. It can also be used in embedded systems and network synchronization where it can provide clock stability and low power consumption.
