These features are dynamic programmable dividers, output jitter filter, power supply noise filter, high level of accuracy and low-ripple output. The device also supports various input and output formats, such as LVCMOS, LVTTL, LVPECL, HCSL, CML and LVDS.The LMK04111SQE/NOPB is suitable for a variety of timing functions, and can be used for applications such as storage area networks, recording and monitoring systems, telecommunications, clock and data distribution, and many more.LMK04111SQE/NOPB Application Field
The LMK04111SQE/NOPB is a low-cost, low-power, high-frequency clock generator suitable for high-performance systems and equipment. It provides reliable and precise signal timing for a variety of applications such as storage area networks, recording and monitoring systems, telecommunications, clock and data distribution, and many more.LMK04111SQE/NOPB Working Principle
The LMK04111SQE/NOPB consists of two main components, a Voltage Controlled Oscillator (VCO) and a Phase-Locked Loop (PLL). The input of the device is either an external reference clock or a crystal oscillator. The external reference clock is fed into the VCO, which outputs a signal with a frequency and phase determined by the input. The VCO’s output signal is then fed into the PLL, which is used to divide the signal into the desired output frequencies.The output frequencies can be adjusted on the LMK04111SQE/NOPB via the Select input. This input is used to control a digital divider chain, which allows the user to select from a range of user-programmable output frequencies.The LMK04111SQE/NOPB also includes an advanced jitter filter, which allows for the output signals to operate at low jitter levels, even when receiving noisy or distorted input signals.In summary, the LMK04111SQE/NOPB is a high-performance, low-jitter, low-noise, programmable clock generator. It provides reliable and precise signal timing for a variety of applications such as storage area networks, recording and monitoring systems, telecommunications, clock and data distribution, and many more. It is a low-cost, low-power, high-frequency clock generator suitable for high-performance systems and equipment.
