Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers
The LMK04033BISQE/NOPB is a highly-integrated, ultra-low jitter clock generator. It provides a fully-customizable PLL that can synthesize low jitter clock outputs from a wide range of input clocks. The synthesizer can be used to generate frequencies up to 550MHz, which makes the device ideal for applications that require high-frequency, low jitter clocks.
Application Field
The LMK04033BISQE/NOPB is suitable for a wide range of applications, including high-speed communications, test and measurement, precision instrumentation, and automotive and industrial systems. The ultra-low jitter clock generator provides an ideal solution for high-accuracy clock and timing requirements, especially for applications that require high speed data transmission and time synchronization between different devices.
Working Principle
The LMK04033BISQE/NOPB clock generator uses a PLL to generate clock outputs from a range of reference inputs. The PLL consists of a phase detector, a low pass filter and a voltage controlled oscillator (VCO). The phase detector compares the reference clock input with the feedback clock from the VCO and produces an error signal. The error signal is filtered and then used to control the frequency of the VCO. By changing the control parameters of the PLL, such as the feedback frequency, the output frequency can be changed.
The LMK04033BISQE/NOPB also incorporates an unmatched crystal filter that reduces jitter even further. This filter is used to reduce the jitter on the input clock and the output clocks, which helps to ensure that the clock signals have low error rates. The filter is adjustable, allowing for further customisation of the clock jitter levels.
The LMK04033BISQE/NOPB can also be used to generate clock outputs with different frequencies. Using the built-in dual multiplier, the clock generator can be used to generate two clock outputs with different frequencies, thus enabling a multi-channel application. The dual multiplier has two output select inputs and two user-selectable feedback divider ratios, which makes it possible to generate one or two output frequencies from one reference input.
The LMK04033BISQE/NOPB also features integrated power management and sophisticated power supply layout. It supports both 3.3V and 5V supply voltages, as well as configurable power-down functionality. This provides an easy and safe way for designers to implement dynamic power savings. In addition, the device uses a spread-spectrum clock (SSC) to reduce electrical noise on the clock outputs and to reduce EMI emissions.
Conclusion
The LMK04033BISQE/NOPB is a highly-integrated, ultra-low jitter clock generator. It provides a highly-customizable PLL that enables designers to generate high-frequency, low-jitter clocks from a variety of input sources. The integrated crystal filter reduces jitter even further, while the dual multiplier enables designers to generate two output frequencies from one reference input. The device also features advanced power management, making it an ideal choice for high-accuracy clock and timing requirements.
