Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers
The 5P49V5914B509NLGI8 is an advanced clock generator and programmable frequency synthesizer that functions as a single device solution to high frequency clock generation needs. It is designed to provide cost savings and a highly reliable power source that have become increasingly important. With up to four clock outputs, this device can simultaneously generate multiple clock signals with high precision accuracy and stability over a wide temperature range.
The 5P49V5914B509NLGI8 is a versatile product, suitable for a variety of applications, such as telecommunications, data acquisition, Ethernet networks, industrial automation, and test and measurement. It uses a Phase Locked Loop (PLL) to generate highly accurate and stable clocks with very low jitter. This is a very important feature for applications that require very tight time specifications. 
The 5P49V5914B509NLGI8 offers a wide range of frequency synthesizer options, allowing it to be set to a specific frequency or range of frequencies. This makes it highly suitable for a range of network and telecom applications which require clocking devices to operate at a particular frequency for each node on the network. The product also comes with a wide range of programmable features and can be easily configured, according to the customer’s exact needs.
The 5P49V5914B509NLGI8’s working principle is based on the use of an external voltage controlled oscillator (VCO). This input to the device’s core is connected to a phase detector and a loop filter. The phase of the reference signal is compared with the VCO, and the output of the phase detector is given to the loop filter. The loop filter imposes an appropriate feedback action and controls the voltage of the VCO, causing the VCO to be adjusted to exactly the same frequency as the input reference signal.
The device also uses a frequency divider to generate the appropriate clock outputs. The frequency division ratio is set by the external resistor values connected to the control inputs. The device’s frequency division ratio is adjustable in a range from 1:2 to 1:8, and can be changed on-the-fly by changing the associated external resistor values.
The 5P49V5914B509NLGI8 can provide an excellent clock signal solution for a wide range of modern applications. The device offers a comprehensive set of features, and as such is suitable for a variety of applications. It offers highly accurate and stable clock signals over a wide range of temperatures, and its programmable configuration makes it ideal for applications requiring a custom clock signal solution.
