The LMX2531LQ2294/NOPB is a highly integrated frequency synthesizer, offering wide frequency coverage in a compact form factor. It is designed to generate an Accurate Clock (AC) in order to control the frequency of an RF signal, providing the user with a reliable, low jitter, and low phase noise solution.

The LMX2531LQ2294/NOPB is a pin-compatible replacement for the industry-standard Valpey-Fisher VF21401, providing a low-cost upgrade without sacrificing performance. The LMX2531LQ2294/NOPB features a high-performance PLL and frequency synthesizer core with a programmable output frequency up to 2450 MHz. The device includes an integrated low-noise high performance Voltage Controlled Oscillator (VCO). An internal Phase Locked Loop (PLL) circuit is able to maintain tight phase and frequency accuracy.

This Frequency Synthesizer PLL clock generator is ideal for telecom, datacom, and storage applications, including networking equipment and base station applications. It is designed to provide superior phase-noise and jitter performance, and offers a wide frequency range that allows customers to use one hardware design and only change the software to support multiple frequencies.

The LMX2531LQ2294/NOPB offers a wide range of programmable features, including generation of a stable AC out of one or two different PLLs, single or dual loop operation, programmable loop bandwidth, VCO frequency control, pre-divider and programmable output frequency. It also offers an integrated bias regulator, an Open Loop Detect feature to detect out-of-lock conditions, and an adjustable Lock Detect feature to provide robust operation, with all of these features being programmable and controllable, making it an excellent clock generator for applications requiring tight synchronization.

In addition, the LMX2531LQ2294/NOPB offers up to four CMOS programmable dividers, allowing for distributed control of signals across multiple networks. The LMX2531LQ2294/NOPB also features an on-board crystal oscillator for added frequency stability, which is designed to ensure low phase noise, jitter, and fast lock times.

The LMX2531LQ2294/NOPB is suitable for applications that require precise synchronization and phase noise control. It is designed to provide excellent results and reduce system integration costs. It is a reliable and cost-effective clock solution, so it is perfectly suited for a wide range of applications, such as telecommunications, computing, and storage.
