The LMX2541SQ2060E/NOPB is a wideband radio frequency (RF) synthesizer designed to support wireless communication in both frequency division multiplexing (FDM) and time division multiplexing (TDM) systems. LMX2541SQ2060E/NOPB is ideally suited for mobile radio, multiple access radio and other applications requiring low-noise, low-power consumption and high dynamic range.It is part of the family of clock/timing-clock generators, PLLs and frequency synthesizers.

The LMX2541SQ2060E/NOPB, with its small size, low power consumption and Arduino/Raspberry Pi compatibility, is perfectly suited for embedded applications. It has the unique ability to provide almost the whole spectrum of signals from 500 kHz to 4.5 GHz in one device, making it the ideal choice for IoT devices with limited space, power, and compute power. This integrated clock generator supports phase locked loops (PLLs) and frequency synthesisers applications. It features various features like programmable output bandwidth, 2 separate 10 kHz-250MHz VCXO reference inputs, two independent output channels and a single fractional-N synthesizer.

The LMX2541SQ2060E/NOPB has many different functionalities. Such as, it provides a wide bandwidth adjustable output with low jitter, low noise and wide locking range, which makes the device well suited for low power and high speed applications in various electronic components including cell phones, base stations, navigation systems and radio communications. In addition, the device has a dual output, with each output capable of providing up to 1 GHz of output frequency. Last, but not least, the device supports programmable output amplitude, as well as a dual-phase mode for applications with different frequency requirements for each output.

The main working principle behind the LMX2541SQ2060E/NOPB is the use of voltage-controlled oscillators (VCOs). It uses two of these VCOs to generate the main clock frequencies. To increase the frequency range (500 kHz to 4.5 GHz), the device uses a phase locked loop (PLL) to combine the two VCO signals. The PLL's output is then sent to two separate output channels. In addition, the device also allows for an integrated voltage-controlled crystal oscillator (VCXO) to be used as a reference, in order to further refine the output frequency. By changing the VCXO's frequency, the system can be adjusted to the precise frequency needed.

The frequency of the VCXO can be adjusted with a frequency programming bus, allowing for precise control of the output frequencies. The LMX2541SQ2060E/NOPB also features selectable output amplitudes, allowing for the precise control of power levels at the outputs. In addition, the device has a range selection pin, allowing for selection of either 10kHz to 250MHz in either single-phase or dual-phase mode.

In conclusion, the LMX2541SQ2060E/NOPB is a wideband RF synthesizer with excellent frequency locking range, low jitter and low noise. With its multiple output channels, programmable frequency range and voltage-controlled crystal oscillator (VCXO) reference, it is ideal for many communication and embedded applications. Furthermore, its power consumption and small form factor makes it well suited for IoT applications where space and power is limited.
