DS1100U-40/T&R products from Maxim Integrated Products are stand-alone delay lines designed for frequency synthesis and pulse shaping applications.

These products are 8-bit, high-performance, low-power quarter-rate delay lines designed for seamless connection to other synthesis circuitry, such as phase-locked loops (PLLs) or spectrum compatibility synthesizers, for generation of a frequency reference or oscillator output. The DS1100U-40/T&R delay line is suitable for pulse shaping application into the MHz range.

The DS1100U-40/T&R is available in either the package option or tray option, each consisting of 1 or 2 standard IC lengths. Each IC length contains a total of 40 of the 8-bit delay line devices. The single length option contains a maximum of 8 devices and is available to support a frequency range of up to 40 MHz. The double length option contains up to 16 devices and is available to support a frequency range of up to 80 MHz. The maximum frequency range of the delay line can be extended by using additional IC lengths.

Working Principle

The DS1100U-40/T&R operates on a quarter-rate basis, where each delay line contains four 8-bit delay line stages. These stages are designed to give a uniform pulse width and pulse latency for each stage. The pulse width and latency are adjustable with an external voltage (Vtrim) which can be used to trim the output waveform for maximum accuracy. The trim voltage can also be used to adjust the pulse width of the output waveform.

The DS1100U-40/T&R also features a selection pin which can be used to select the active delay line stage. This selection pin allows the user to select which of the four delay line stages is active at any given time. The active delay line stage is then used to generate the waveform output. Once the active stage is selected, the output waveform is generated by clocking the selected stage with an external clock signal.

The DS1100U-40/T&R also includes a test input pin which is used to verify the proper operation of the device. This testing pin can also be used to determine the actual delay line operation of each of the delay line stages. Finally, the device also features a power down feature which can be used to reduce the power consumption of the device when not in operation.

Application Field

The DS1100U-40/T&R from Maxim Integrated Products is designed for use in a variety of applications including frequency synthesizers, pulse shaping, and clock distribution. This product is ideal for applications that require high-speed, low power delay line solutions in frequencies up to 80MHz. The flexibility of the delay line also makes it suitable for a range of clock and frequency applications, such as frequency synthesisers, oscillator outputs, pulse width modulation and pulse shaping. Therefore, this product is ideal for a wide range of clock and frequency applications in various industries, including communications, automotive, storage and networking.

In addition to its use in frequency synthesisers, the DS1100U-40/T&R can also be used for clock distribution applications. This device can be used to create clock signals of any frequency, from Hz to MHz, in order to save power and reduce the complexity of the circuit. By using the DS1100U-40/T&R, it is possible to create multiple clock frequencies with different latency and pulse widths. This means that the device can be used to create multiple clock signals with various duty cycles, making it suitable for clock distribution of any application.

Finally, the DS1100U-40/T&R can also be used as a pulse shaping device, operating in the MHz range. The ability to easily trim the output waveform makes it ideal for use in pulse shapers, allowing users to create waveforms of various shapes and widths. This is especially useful in applications such as wired and wireless communication, video and audio streaming, and medical imaging.

Conclusion

The DS1100U-40/T&R from Maxim Integrated is a high-speed, low-power, quarter-rate delay line designed for seamless connection to other synthesis circuitry, such as phase-locked loops (PLLs) or spectrum compatibility synthesizers. This device can be used for frequency synthesis, pulse shaping, and clock distribution applications, operating up to the 80MHz range. The flexibility of the delay line makes it suitable for a range of applications, making it the perfect choice for both clock and frequency applications.
