5P49V5923A505NLGI8

The 5P49V5923A505NLGI8 is a clock generator, phase locked loop (PLL) and frequency synthesizer. It is used for precision timing and to transfer radio signals between multiple devices.

In the application field, the 5P49V5923A505NLGI8 is used to provide highly precise frequency synthesis for precise timing applications such as timing synchronization, frequency hopping, and signal processing operations. It offers a wide bandwidth of operations, up to 50MHz and covers a range of frequencies from 1MHz to 50MHz. The 5P49V5923A505NLGI8 is specifically designed to be used in a variety of applications, from Wi-Fi and cellular base stations to wearable devices and automated test systems.

In terms of its working principle, the device is a PLL-based clock and frequency synthesizer based on a reference oscillator. It uses two multiplying digital frequency synthesizers (DFSs), one for input and one for output, to provide continuous frequency variation and programming flexibility. The two DFSs are connected through an analog voltage-controlled oscillator (VCO) that provides both positive and negative digitally controlled voltage tuning range. The VCO output is also synchronized to the input frequency reference clock, providing low jitter and superior frequency resolution.

The output of the 5P49V5923A505NLGI8 can be programmed to any of a wide variety of frequencies, depending on the tuning range of the particular application. The device also features programmable frequency resolution, allowing for precise fractional-N frequency control. It also includes a range of functions such as power sequencing and a power fail detect, which provide enhanced functionality in designs requiring precise control.

The 5P49V5923A505NLGI8 is a versatile, low-cost solution for the most demanding timing applications. With its low power consumption, small size, and wide tuning range, it is ideal for applications ranging from high-performance telecommunications systems to low-power wearables and beyond.
