The LMX2531LQE1312E/NOPB is a clock generator, phase-locked loop (PLL), frequency synthesizer that operates in a very wide frequency range. The device can produce frequencies from 3kHz up to 4.2GHz and works with very low power consumption, making it suitable for applications that have a low power budget or need the highest level of automation

This part is often used in communications and telecommunications systems, such as base stations, routers, and access points. The architecture of the LMX2531LQE1312E/NOPB allows it to operate with a wide variety of output frequencies and rapidly generate frequency hopping patterns. This makes it ideal for use in critical communications where jamming or interference is a concern.

The LMX2531LQE1312E/NOPB consists of an integrated RF synthesizer, a low-noise voltage-controlled oscillator (VCO), and a loop filter. The integrated synthesizer accepts a single crystal reference signal, such as 10MHz, and generates a fraction of that frequency. The signal is then passed through the VCO to generate a frequency that is the product of the reference signal and the synthesizer settings.

The loop filter combines the reference signal and the output of the VCO to control the frequency of the output signal and maintain phase-lock between them. The resulting signal is fed back to the VCO to adjust its frequency as necessary. This allows the device to generate multiple output frequencies while still maintaining a low level of noise, suitable for precision applications and those that depend on accurate timing.

The LMX2531LQE1312E/NOPB makes it easy to implement multi-band operation and phase-lock loops (PLL). Its integrated loop filter and wide tuning range help reduce cost and complexity. Through clever design and careful component selection, the device is able to maintain low jitter and low phase noise, important factors in applications where timing accuracy is critical.

The LMX2531LQE1312E/NOPB is a versatile clock generator, phase-locked loop (PLL) and frequency synthesizer, capable of producing frequencies from 3kHz to 4.2GHz, with a low power budget. Its architecture makes it well suited for communications and telecommunications applications, thanks to its ability to generate frequency hopping patterns and tight phase-lock control. The device is also highly capable of producing accurate timing signals, making it especially useful in environments where timing accuracy is essential.
