The LMX2541SQ3320E/NOPB is a high frequency, quad-channel, low power voltage controlled oscillator (VCO) designed to address a wide range of application fields. As a member of the new family of synchronous interface PLL clock generators, the LMX2541SQ3320E/NOPB provides flexible, low power alternative to discrete, crystal, and thermally-driven oscillator designs.

The LMX2541SQ3320E/NOPB is an advanced PLL integrating a voltage controlled oscillator (VCO) with a programmable frequency divider and multiple channels for output clock generation. It utilizes two or four internal VCOs that are independently selectable to output high frequency programmable clock signals. Each VCO has a frequency range from 176.32 MHz to 1.315 GHz. Each input and output of the LMX2541SQ3320E/NOPB can be configured for either differential or single-ended applications.

The programmable divider is designed to provide frequencies up to 179.2 MHz with divided outputs such as 10/2/2, 10/2/3, 10/3/3, 16/2/2, etc. The LMX2541SQ3320E/NOPB also incorporates a programmable phase shift function to produce extremely precise phase differences between multiple outputs, eliminating the need for external trimming of frequency and phase circuits.

The LMX2541SQ3320E/NOPB is designed for applications in consumer, industrial and communication equipment such as Smartphone, tablet and optical products. It is packaged for surface mount applications and features a 2.5 x 2.5 mm, 25-lead LQFP package with an exposed die pad. It also has an On-chip programmable output phase shift from 0° to 90°. It can operate at supply voltages ranging from 1.8V to 3.3V, with a maximum current consumption of 8mA. The LMX2541SQ3320E/NOPB is designed to be compatible with industry standard GPPLL Clock Synthesizer designs, making it ideal for high performance, low power design.

In addition, the LMX2541SQ3320E/NOPB includes two output drive enhancements (ODT) options, one for high noise immunity and one for low power and low jitter operation. The ODT is supported by a two-stage slew rate control circuit to reduce the risetime and dwell time of each output up to 20ns.

The LMX2541SQ3320E/NOPB is easy to configure and program for all clock generation applications. Its features and architecture are designed to reduce the component count and design time, while providing the highest levels of flexibility and performance. Moreover, thanks to its low power consumption, the LMX2541SQ3320E/NOPB is ideal for portable applications.

The working principle of the LMX2541SQ3320E/NOPB is based on the use of a precision voltage-controlled oscillator (VCO) and a programmable frequency divider. The VCO generates a signal with a specified frequency and a specific phase shift. The programmable frequency divider divides the output signal from the VCO into multiple valid frequencies. By selecting different output waveforms, the frequency of the output signal is determined by the programmable frequency divider.

The LMX2541SQ3320E/NOPB also features a programmable phase shift between the output signals. This allows for precise control of the phase relationship between multiple outputs in order to ensure an optimum clock molecule for any synchronous system. The onboard wide bandwidth differential amplifiers also allow for wide temperature range and high signal integrity applications.

The LMX2541SQ3320E/NOPB is a powerful clock generator with many advantages. It is best suited for applications that require high performance and reliable clock signal output with low power consumption and a wide frequency range. It is one of the best devices to provide optimal frequency synthesis and phase shifting in cutting-edge devices and mobile devices.
