The LMK04110SQE/NOPB is a high-performance clock generator and fanout buffer designed for a range of applications. It is designed to combine ultra-low frequency jitter and low-noise, low-skew buffering. It is ideal for high-performance systems where critical clocking performance is needed.

The LMK04110SQE/NOPB can be used as a frequency synthesizer, allowing users to select and configure various clock frequencies using a fast-acting serial interface, with frequencies ranging from 156.25 MHz to 1.25 GHz. This can be done without any external components, making the LMK04110SQE/NOPB a simple and cost-effective solution.

The LMK04110SQE/NOPB also includes a selectable master/slave port (MSP) that can be used to cascade multiple devices, allowing users to cascade up to four devices without doing any additional logic design. The MSP also ensures that all devices are configured to the same frequency.

The device is also equipped with a differential fanout buffer that provides multiple outputs, each with different levels of skew and skew control. The LMK04110SQE/NOPB can also be used to drive SMA buffers, allowing them to provide up to 1600 mV p-p of output drive for applications that require a lot of power. The outputs are also specified for operation from up to -45 °C to +125°C.

In terms of its working principle, the LMK04110SQE/NOPB is designed to use an advanced phase-locked loop (PLL) technology. The PLL consists of two main parts: the phase detector and the voltage-controlled oscillator (VCO). The phase detector compares an input reference signal to the output signal and uses this information to adjust the phase of the output signal, ensuring that it is always in sync with the reference signal. The VCO is responsible for the generation of signals at a higher frequency than the reference signal, allowing it to generate signals of different frequencies from the reference signal.

The LMK04110SQE/NOPB is designed to provide excellent clock performance, low jitter, and low skew. Its low-skew outputs make it well suited for high-speed applications such as 10 GbE, GbE switch and router designs, as well as PCI Express, DDR3 and DDR4 applications where clock accuracy and phase-locking are critical. It can also be used in microwave and RF applications such as those requiring ultra-low phase noise performance. In addition, the device is compliant with the JEDEC MO-229 standards.

The LMK04110SQE/NOPB is an ideal solution for applications requiring high-performance clock generation, low jitter and low-skew buffering, and can provide a cost-effective solution for a variety of clock applications. It is a versatile clock generator and fanout buffer that can be used to drive a variety of clock and data lines.
