The LMK04828BISQX/NOPB includes an integrated voltage controlled oscillator (VCO) and three integrated low-noise programmable frequency dividers (FDs). The device operates over a wide operating temperature range. It has an easy-to-use integrated programming interface that allows for quick and seamless device setup.

The LMK04828BISQX/NOPB is a highly adaptive and configurable clock generator. It is designed for use in high-end telecom equipment, offering excellent flexibility, programmability and customizability. The device can be used to generate a wide range of output frequencies from 10-125 MHz, including frequently used High Density Interconnect (HDI) frequencies such as 25, 50, 75 and 100 MHz.

The working principle of the LMK04828BISQX/NOPB clock generator is based on an integrated phase-locked loop (PLL). The PLL comprises of a voltage-controlled oscillator (VCO) and three frequency dividers. The input frequency is divided by the frequency dividers, and the divided signals are used to control the VCO. The output frequency (and phase) of the VCO is then compared to the input frequency, and the VCO is adjusted to achieve the desired output frequency (and phase). This process is repeated continuously, and results in a highly stable output frequency.

The application field of the LMK04828BISQX/NOPB clock generator is primarily in the telecom industry. It is suitable for a wide range of applications, including wireless/wireline base stations, femtocells/picocells, cellular backhaul, densification and fronthaul networks. It can also be used for digital baseband systems, including edge applications such as IoT and local computing.

In summary, the LMK04828BISQX/NOPB is a low phase noise clock generator designed primarily for use in the telecom industry. It is a fractional-N type solution with an integrated PLL, allowing it to generate a wide range of output frequencies. It also offers excellent phase noise performance, low reference spurs, low jitter and low power consumption.
