The LMX2531LQX3010E/NOPB is a high-speed PLL clock generator targeted for fast and accurate jitter clean clocks. The device integrates a 10-bit dual D/A converter, input samples for feedback, and a voltage controlled oscillator (VCO) to produce system clock frequencies from 200 MHz to 1.5 GHz. It is widely used in many different applications in aerospace, communication and industrial sectors.

The working principle of the LMX2531LQX3010E/NOPB can be broken down into several essential pieces. First and foremost, an external reference clock is applied to the device, and then two wide dynamic range 10-bit differential D/A converters are used to receive the required output clock frequency setting. These two converters, which require adjustable input signals, act as a feedback loop, keeping the output frequency close to the user-specified frequency. Then, the LMX2531LQX3010E/NOPB PLL engine, unlike most standard PLLs, uses the input clock samples instead of the reference clock to more accurately measure the frequency error.

The output from the LMX2531LQX3010E/NOPB is a clean low jitter clock that is highly stable over time and temperature. This is achieved by the VCO design which allows for wide output frequency range, and by the two 10-bit differential D/A converters which keep the output clock frequency close to the user-specified frequency.

The wide range output frequencies make the LMX2531LQX3010E/NOPB ideal for applications that require a precision timing source such as telecom and communication infrastructure applications, as well as satellite and aerospace communication. In addition, many industrial applications such as machine vision, motion control and automatic test equipment have adopted the LMX2531LQX3010E/NOPB for high-speed timing.

The LMX2531LQX30101E/NOPB clock generator is designed to provide the best possible performance for system clocking. Its high performance, low jitter, wide frequency range and low power consumption make it an ideal solution for customers in need of a reliable and precise timing source.
