• Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

  LMX2581ESQE/NOPB is an integrated clock generator and synthesizer that is a compact and highly efficient way of generating multiple low power clock signals from a single reference. Its integrated low-noise PLL, low-power VCO, regulated charge pump, and convenient programming interface make it suitable for a variety of applications ranging from digital television to communications and medical systems.

  Application Field:

  The LMX2581ESQE/NOPB can be used for a wide array of applications where low-power and low-noise clock signal needs to be generated from a single reference. It can be used in digital television and communications systems. It can also be used in medical systems due to its features such as low noise and low power consumption. This device can generate multiple clock signals with an output amplitude of up to 800mV, which makes it suitable for situations where precision timing is required.

  Working Principle:

  The LMX2581ESQE/NOPB uses a low-noise PLL with a low-power VCO, a constant voltage charge pump, and a programming interface. The PLL locks on to the reference signal and generates multiple outputs, and it includes an adjustable charge pump for voltage control. The constant voltage charge pump can also provide power to other devices, as needed. The programming interface allows the user to configure the device to generate multiple clock signals, including output frequencies from 0.2MHz to 7MHz, with an amplitude of up to 800mV. The LMX2581ESQE/NOPB also has a low power consumption of 70mW, which makes it suitable for use in mobile or embedded applications.
