ICS854054AGLF is a desirable clock and timing device for communication and networking applications. The company expanded its standard ICS854054A family of Low-Voltage Positive-Edge-Triggered (LV P-ET) clock distribution products with the 4-channel ICS854054AGLF device. This device offers a combination of unusually low power consumption, low output-to-output skew, and jitter that make it ideally suited for use in mobile, cellular, and other low power applications.

Application Field

The ICS854054AGLF clock driver provides four fully differential, differential-mode PECL outputs. This device is capable of transmitting data at frequencies up to 350MHz across PCB traces with minimal jitter. This device is designed for use in very low-power applications such as networking, cellular, and handheld devices, and it is also suitable for applications where output-to-output skew is a concern.

The ICS854054AGLF clock driver is ideal for the high-speed serial data communications and storage protocols used in storage and computer networks, including SATA, SAS, 8b/10b and 64b/66b. It can also be used in processor-based applications, where its low-power performance is a key factor. In addition, it is suitable for use in applications where the accuracy of the skew between multiple clock outputs is important, such as encryption and decoding.

Working Principle

The ICS854054AGLF clock distribution device utilizes a unique approach to clock distribution. This approach is based on the concept of self-timed control logic gates. The self-timed logic gates are used to divide the clock signal into two parts. The first part is used to control the timing of the two positive edge-triggered (PET) outputs, while the second part is used to control the timing of the two negative edge-triggered (NET) outputs. This approach provides the benefits of low-power, low-jitter and low-skew performance.

The ICS854054AGLF clock driver contains a low-voltage differential buffer (LVDB) to drive the outputs, along with a combined input/output termination scheme to reduce ringing on inputs and outputs. The combinedterminator scheme allows signals to be driven from both inputs and outputs, which reduces losses associated with connecting multiple drivers together. The outputs offer adjustable slew rates for fine tuning, as well as a differential output impedance.

The ICS854054AGLF provides a unique combination of low-power performance and low-skewclock outputs. It is ideal for clock-doubling applications (transmission of data at twice the reference clock frequency), as well as clock distribution applications. It is most commonly used in applications where output-to-output skew must be minimized, such as encryption and decoding.

Conclusion

The ICS854054AGLF is an ideal clock and timing device for communication and networking applications due to its low-power performance, low-jitter clock outputs, and low-skew output-to-output performance. It is suitable for applications where output-to-output skew is a concern, including encryption and decoding applications. Additionally, it provides adjustable slew rates for clock-doubling applications, and a differential output impedance. The ICS854054AGLF offers a superior alternative to traditional clock and timing solutions.
