Introduction

ICS853054AGLFT is a clock buffer family which includes LVDS, HCSL, CML, and LVPECL outputs in the same package. It is a single ended-to-differential clock buffer best used in ASIC, FPGA, and SoC designs. The device is designed to provide excellent jitter and slew rate performance with a wide supply voltage from 2.3 V to 5.5 V. It also features programmable output voltage levels and selection of output drive and current levels.

Application Field

The primary application for this device is in communications and networking where lots of data needs to be transmitted between and among systems. These parts are often used to clock data into ASICs, FPGAs, and SoCs and provides an ideal solution when there is a need to distribute an input clock signal to multiple receivers. Without this device, one would have to size their transmission buffer to match each output load which can cause delays, consume unnecessary power and increase system complexity.The ICS853054AGLFT can be used in any wide variety of communication protocols such as Ethernet, Fibre Channel, InfiniBand, Serial ATA, USB, PCI Express, and other industry standard applications. Additionally, it can help lower total system power by providing a regulated voltage and adjustable current levels.

Working Principle

The ICS853054AGLFT clock buffer employs a differential output configuration to provide a low-jitter clock signal which is immune to most external electrical noise and electromagnetic interference (EMI). The differential architecture helps to reduce the jitter on the outputs due to the fact that the two signals are complementary and therefore keep each other synchronized. The device is designed to provide excellent jitter and slew rate performance by utilizing a pre-determined, programmable output voltage and selection of output drive and current levels. The output slew rate is adjustable to reduce EMI and help comply with industry requirements. The device has three selectable current levels, high drive current (2.5 mA), low drive current (1 mA), and a low power consumption mode (100 μA).Moreover, its output voltage levels are programmable. The sources voltage range from 2.3v to 5.5v and the outputs are adjustable anywhere between these levels. It allows users to adjust the levels to match the input buffer of the destination component which provides better signal integrity and drive capability.

Conclusion

The ICS853054AGLFT is a great clock buffer family which reduces EMI and total system power consumption while providing excellent jitter and slew rate performance. Its ability to program the output voltage levels also provide better signal integrity and drive capability. It is ideal for a wide variety of communication protocols in the communication and networking.
