The LMK04805BISQE/NOPB is a Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers device. It is a 1.2GHz Programmable PLL. It is specifically developed for use in low-power and small form factor applications in networking, communication and consumer electronics, such as consumer electronics, Network Security and other related applications.

The LMK04805BISQE/NOPB has multiple output options that can be used for various applications within the same system. It has very low power consumption and is easy to setup, making it an ideal choice for low power and low complexity designs.

The LMK04805BISQE/NOPB has a very wide operating frequency range, from 500MHz to 1.2GHz. The output frequency can be set through a variety of ways, including a programming interface, manual external resistors, or external VCOs.

The LMK04805BISQE/NOPB also has an integrated Spread-Spectrum capability that is used to reduce the peak emission levels. This helps reduce emissions, as well as reduce radiated emissions.

The device also has multiple integrated features that help to improve the reliability and accuracy of the output signals. These include a programmable reference clock Divider and an on-chip crystal oscillator. The reference clock divider output is used to derate the input clock, allowing the output frequency to be accurately locked with the input clock frequency.

In addition to the on-chip features, the LMK04805BISQE/NOPB also has an integrated loop filter that increases the noise immunity of the design. This makes it more reliable in noisy environments. The integrated loop filter also provides better phase noise reduction.

The main function of the LMK04805BISQE/NOPB is to generate a clock signal from an input signal. It does this by dividing the input signal into two parts. The first part is used to generate the output clock, and the second part is used as the reference signal for the PLL.

The output frequency of the device is then derived from the reference signal, using the programmable loop parameters. The output frequency can be precisely controlled by changing the loop parameters, including the reference clock divider, the phase-locked loop (PLL) gain and loop filter values.

The PLL gain is the ratio of the output frequency to the reference signal. A higher PLL gain gives a higher frequency output. The loop filter values determine the bandwidth and stability of the output clock. These two parameters are used to tune the PLL to achieve the desired output frequency. The output frequency can also be adjusted through external VCOs or by manual external resistors.

The device also has a power saving mode and a low-power start-up, which allows the controller to enter and exit the lower power saving state without any extra startup time at the nominal power level. The device also includes fail-safe circuitry that ensures that the device will continue to generate an accurate clock signal even if the main power supply fails or is disconnected.

The LMK04805BISQE/NOPB has various uses, from communications, networking and consumer electronics to requirements for low power and small size. It is capable of providing a wide range of output frequencies, from 500MHz to 1.2GHz, and with the integrated noise immunity and fail-safe capability, is suitable for any application.
