Introduction to DS1100LZ-200+T Clock/Timing - Delay Lines With Application Field and Working Principle

Delay Lines are an important member of the Clock/Timing family because they provide a stable, precise method of providing precise timing to a multitude of systems. The DS1100LZ-200+T is a well-known Delay Line from Texas Instruments that offers high-speed performance, precision and reliability in a wide range of application fields. In this article, we will explore the DS1100LZ-200+T and its applications, as well as the principles behind its excellent performance.

What is the DS1100LZ-200+T?

The DS1100LZ-200+T is a digital delay line designed to provide precise timing intervals, waveform shaping capabilities, and rectangular pulse generation. It is a Dual-Channel Delay Line, meaning that it supplies two groups of the same output signals with one group delayed from the other by an adjustable amount of time. The maximum delay time of the DS1100LZ-200+T is 12 microseconds, with an adjustable resolution as low as 200 picoseconds. It operates with a single 3V or 5V supply voltage, with between 2.4V and 5.7V for its differential output pins. Power consumption of the device is quite low, at about 1.2 mA with a 3V supply.

DS1100LZ-200+T Application Fields

The DS1100LZ-200+T finds use in a variety of applications, such as:

• Input/Output Interface Timing – The DS1100LZ-200+T can be used to synchronize multiple input/output ports, as well as to generate precise delays that ship communication between different systems.
• Electrical Signal Timing – In systems where electrical signal timing is critical, the DS1100LZ-200+T can be used to supply precise and repeatable timing to devices.
• Waveform Shaping – The DS1100LZ-200+T can be used to generate waveforms of specific shapes and amplitudes for signal processing purposes.
• Precise Pulse Generation – For applications that require precise, high-speed rectangular pulses, the DS1100LZ-200+T can be used to generate such pulses with a great degree of accuracy.

DS1100LZ-200+T Working Principle

The DS1100LZ-200+T uses a Delay Coefficient Adjustment (DCA) capability to provide precise, repeatable delays. The device has an internal loop of 32 voltage-controlled delay lines (VCDL), which are connected in parallel. The VCDLs are connected with a tapped delay line, and an adjustable delay coefficient register adjusts the delay of the VCDLs by controlling the voltage that passes through the tapped delay line. The DS1100LZ-200+T also has an output logic circuit that generates the output signals. The output logic block takes the data stream and uses a variety of tri-state output buffers to generate the output signal, which is then fed into the VCDLs. The output signal then passes through the VCDLs, with each delay determined by the DCA. The signal is then fed into a combiner, where all of the VCDLs’ outputs are summed together to form the final signal.

Conclusion

The DS1100LZ-200+T from Texas Instruments is an excellent Delay Line for a wide range of applications. Its dual-channel design, low power consumption, and adjustable resolution make it ideal for input/output synchronization, electrical signal timing, and Precise pulse generation. Its Working Principle is based on a Delay Coefficient Adjustment mechanism, which allows for precise and repeatable delay intervals.
