The DS1100LU-45+ is a low-cost, low-power precision clock delay line from Texas Instruments. The device uses a proprietary digital signal processing (DSP) technology to provide superior accuracy and jitter performance compared to conventional analog delay lines. It is designed for use in high-speed data clock synchronization, timing, and frequency reference applications.

Oscillators and delay lines are one of the integral components of clock and timing systems. Delay lines provide precise and adjustable phase shifting for accurately timed signal or clock transmission. Delay lines are used in many different types of applications, such as telecommunications, network synchronization, timing recovery, memory synchronization, and other clock and timing circuits.

The DS1100LU-45+ is specifically designed to provide a precise delay between two clock input signals. It can be used to delay a clock signal to better synchronize multiple signal paths, or to adjust the duty cycle of an inverted input clock signal. The device offers precise control of delay, clock duty cycle, and skew between input and output signals, providing signal integrity and precise timing in critical applications.

The DS1100LU-45+ is constructed of two building blocks. The first is a programmable clock delay line, which consists of several stages of digital signal processing (DSP) blocks. The second is a digital serial logic block, which provides programming of the delay line. The input signal is first passed through the delay line, where it is delayed according to a user-defined time setting. The delayed signal is then passed through the serial logic block, where it is processed and amplified to generate the output signal. The output signal is then sent out of the device.

The DS1100LU-45+ offers a wide range of delay ranges from 1ns to 0000ns and a maximum clock frequency of 1100MHz. The device is programmable using a serial interface, and it is compatible with high-speed serial bus technologies such as PCI Express and USB. The device also features an integrated stabilization circuit for improved performance. The on-chip temperature sensor allows for temperature compensation, ensuring accurate timing characteristics in a wide range of industrial and temperature operating conditions.

The DS1100LU-45+ is ideal for application such as high-speed data clock synchronization, frequency reference systems, and other clock and timing applications. Its low cost and low power consumption make it ideal for a wide range of applications, including industrial control systems, test and measurement systems, automotive systems, and medical equipment. The device’s precise control of skew and duty cycle of clock signals ensures clean and accurate timing in critical applications.
