The LMX2531LQ2080E/NOPB is a precision Clock Generator and Jitter Attenuator which helps customers create devices that work more accurately and reliably with extremely low power consumption, ideal for demanding and space constrained applications.

This integrated circuit is part of the Clock and Timing PLLs family, as it is able to generate any signal up to 3,2GHz with extremely low jitter. This IC is a fractional-N synthesizer that combines a programmable precalibrated VCO and a dual-modulus prescaler in a single monolithic circuit that allows a great flexibility when creating oscillator applications.

The application field for the LMX2531LQ2080E/NOPB is very broad, maybe the best way to know where to use it is to understand its working principle. The device configuration is made by programming several registers, which allows to set a wide range of parameters, such as phase jitter, frequency, output type and amplitude.

The IC consists of a VCO, prescaler and loop filter. The VCO generates frequency and phase noise signals, multiplied by the correct frequency or divided by the correct integer through the prescaler. The output of the prescaler is then conditioned into the output filter. The loop filter also controls the VCO, by keeping the output frequency accurate by accurately controlling the VCO tuning voltage.

The chip also includes a Jitter Attenuator which helps to reduce the spectral power of the reference output clock. This block is useful in applications involving high precision and that requires more stability of the output clock.

The power consumption of the LMX2531LQ2080E/NOPB is extremely low, around 20 to 30 mW, making it the ideal device for low-power applications, such as timing critical applications, wireless communications and many others.

Because of its low power design, wide frequency range, high precision and flexibility, the LMX2531LQ2080E/NOPB is used in many applications that demand high accuracy and small size, like test and measurement equipment, automotive, aerospace, and military/aerospace.

The LMX2531LQ2080E/NOPB is an excellent choice for Clock Generator and Jitter Attenuator applications in Devices needing high performance, low power and small size. Its versatility, precision and low power makes it a great choice for any application needing high accuracy.
