PL123-09NSI-R is a clock buffer/driver from Pericom. It is a low noise and low power device, making it ideal for any applications that require low power consumption. The PL123-09NSI-R operates over a wide supply voltage range from 2.7V to 5.5V, making it suitable for low-voltage applications such as mobile and battery-powered devices. The device features programmable features that allow for tailored output characteristics for improved system performance and reduced EMI susceptibility.

Application Field

The PL123-09NSI-R can be used in a variety of applications in both digital and analog systems. In digital systems, it can be used to buff and/or split input clock signals. The device can also be used as a clock source in digital systems such as memory controllers, logic gates, and DDR devices. In analog systems, the device can be used to drive analog mixing and signal conditioning devices such as ADCs and DACs. It is also suitable for analog clock distribution systems, where the PL123-09NSI-R can be used to buffer an input clock and distribute it to multiple devices.

Working Principle

The PL123-09NSI-R incorporates an input clock signal buffer, multiplexing logic, and an output buffer/driver. The input buffer buffers the incoming clock signal and provides a low-noise output signal suitable for passing through long trace runs. The multiplexing logic then selects which of the output buffers is enabled based on the user-specified settings. The output buffer/driver is then used to drive the output clock signal. The driver is designed to reduce crosstalk and provide accurate, low-noise outputs. Additionally, it can be programmed for a variety of output characteristics to reduce EMI susceptibility.

In addition to its buffering and multiplexing logic, the PL123-09NSI-R is equipped with programmable drivers that can be used to generate low-noise, low-jitter outputs. The device is also equipped with multiple power-down modes, allowing for reduced power consumption in both active and inactive states. Furthermore, the device is silicon-proven, meaning that its clock performance has been rigorously tested and calibrated.

The PL123-09NSI-R is designed to operate over a wide temperature range of -40°C to +85°C. It is available in the industry-standard 8-pin WLCSP package, making it ideal for applications with space constraints. All of these features make the PL123-09NSI-R an ideal solution for any clock buffering/driving or multiplexing application.
