The DS1100LZ-45+ is a high-speed, low-skew Circular Buffer/ Delay Line designed for critical path delay selection in high-performance clock and data distributions (adders, multiplexers, etc.). The DS1100LZ-45+ is part of the popular DS1100 family from Silicon Systems, Inc. and features an internal clock frequency of 5 MHz or greater, with an external clock input up to 150 MHz. It provides a low-skew, high-speed clock distribution solution, with a maximum propagation delay of 45 ns. The device also features low power dissipation, making it ideal for applications where power consumption is a critical factor.

The DS1100LZ-45+ is a delay line and timing module that uses a two-phase access scheme. It is designed to create, regenerate and propagate clock signals to distant nodes and provides clock distributions to all nodes in the system at specified delays. The device contains four separate delay lines: two input lines (A and B), two output lines (D and E), and one loopback line (C). Each delay line has multiple taps that can be configured to provide the necessary delays for clock signal distribution within the system.

The clock input is sent via a terminal connected to the A and B terminals, with each terminal having its own delay line. The delay lines in the device operate in series, with the output from the A line forming the input of the B line. The output from the B line then goes to the C line as a loopback. The D and E lines provide the outputs for the delayed clock signals. The D and E lines feed the output devices at their designated delays, with the C line providing the loopback signal to the input devices.

The DS1100LZ-45+ also features a built-in phase-adjustment capability, which enables it to be used as a phase-alignment tool. It has the ability to adjust the relative phase of the output signals at each of the taps, allowing the user to optimize timing margin, minimize clock skew, and reduce insertion delay. The device also includes an on-board trim-and-test capability, allowing users to quickly and easily adjust the phase settings.

The DS1100LZ-45+ can be used in a variety of applications, including high-performance clock and data distribution, phase-aligning critical data paths, and phase-shifting signals for board or system testing. It is well suited for use in overclocking and power performance optimization applications, as well as Jitter attenuation. The device has a wide range of operating temperature ranges, making it ideal for use in communications, networking, and automotive applications.

In conclusion, the DS1100LZ-45+ provides a high-speed, low-skew Circular Buffer/ Delay Line solution, allowing users to distribute and phase-shift clock signals in critical applications. The device is well-suited for use in high-performance clock and data distributions, phase-aligning critical data paths, and phase-shifting signals for board or system testing. The DS1100LZ-45+ operates from 5 MHz to 150 MHz, providing flexibility and convenience for a wide range of applications.
