9LP505-1HGLF Application Field and Working Principle

Clock/Timing - Application Specific

9LP505-1HGLF is a highly reliable, advanced and low power spread spectrum clock IC, designed to reduce the total radiated noise from products such as servers, routers, ASICs, water meters, electrically-driven pumping systems, and wall-mounted power meters. It integrates a 50MHz low jitter Oscillator, a spread spectrum unlock circuit logic and a fully integrated Programmable logic to accept and process a wide variety of user defined and field programmable parameters. The device is also ideal for applications that call for a high clock speed and low harmonic noise, such as datacom and telecom systems.

The 9LP505-1HGLF has been designed with a 3-wire interface that allows for simple user programming and control. The device is programmed to spread the 50MHz clock output of the device into multiple frequencies and reduce the jitter significantly. This reduces the total harmonic noise of the device output by up to 50% while providing a lower EMI performance than a standard 50MHz clock.

The 9LP505-1HGLF features a complex, yet flexible architecture enabling different technical trade-offs to be allowed. The user programmable parameters include spread amount, spread spread factor, power up/down spread, peak/average spread, pre-delay/attenuation/attenuation rate, and spiking optimization. These parameters allow for flexible adaptation of the system to individual user applications.

The device also integrates a differential ESD protection diode, which is connected across each I/O pin. This provides the capability of protecting the device from external ESD events. The IC also includes a wide logic level range allowing for a variety of voltage levels for user programmable logic. This is beneficial for applications requiring lower power consumption, reducing the area size, or enabling different EMI/EMC regulations.

In addition, the 9LP505-1HGLF integrates a range of features such as integrated pre-programmed spread spectrum parameters, software control options, and selectable pre-programmed pulse cascade timing measurements. All of these features combine to provide flexibility and reduce design time in many custom applications.

Overall, the 9LP505-1HGLF is an ideal device for applications requiring high performance, low power consumption, and wide range of programmable features. As a highly reliable and low power spread spectrum clock IC, the 9LP505-1HGLF can be used in a wide range of applications including datacom, telecom, and industrial control systems.
