DS1135LU-20+T&R Delay Line

Delay lines, in general, are electronic components used to simulate the passage of time by delaying a signal. The DS1135LU-20+T&R belongs to a family of delay lines specifically designed for use in clock and timing applications. This article will discuss the application fields and working principles of the DS1135LU-20+T&R in more detail.

Application Fields

The DS1135LU-20+T&R is a comprehensive programmable delay line. Its versatility makes it suitable for a wide range of applications including, but not limited to: timing and synchronization; frequency shift keying; pulse width modulation; signal buffering; equalization and de-spiking; and filter shaping.

In timing and synchronization applications, the DS1135LU-20+T&R can be used to provide signal delays with low jitter, which is important for maintaining signal integrity. In frequency shift keying (FSK) and pulse width modulation (PWM) applications, the DS1135LU-20+T&R can be used to create envelopes and data synchronizers which in turn can be used for device control and communication applications.

In signal buffering applications, the DS1135LU-20+T&R can be used to buffer and synchronize signals. This is useful for applications where signals need to be accurately routed through a system with minimum distortion. In equalization and de-spiking applications, the DS1135LU-20+T&R can be used to reduce unwanted noise in high frequency signals and improve signal integrity.

Finally, in filter shaping applications, the DS1135LU-20+T&R can be used to modify filter responses and create filters which optimize system performance.

Working Principle

The DS1135LU-20+T&R is an analog delay line which uses a combination of surface-acoustic-wave (SAW) technology and integrated-circuit (IC) technology to realize its timing functions. The heart of the DS1135LU-20+T&R is a SAW delay line which consists of a piezo-electric transducer, an amplifier and a delay line transducer. The SAW delay line convertes electrical signals into acoustic waves which travel along the delay line and are converted back into electrial signals at the end of the delay line.

The output of the delay line is then buffered by an IC which adjusts the delay line\'s total response. The IC also provides isolation, which prevents external noise from affecting the delay line\'s performance. The IC has programmable inputs which allow the user to adjust the response characteristics of the delay line according to their requirements.

The DS1135LU-20+T&R has wide range of features which can be programmed via its parallel port. These features include programmable accuracy, programmable temperature dependence and programmable delay. The accuracy of the DS1135LU-20+T&R is typically within 1%. Additionally, the DS1135LU-20+T&R has a built-in tilt compensation circuit which ensures its accuracy is maintained over changes in temperature.

The programmable input pins of the delay line can also be used to adjust its delay characteristics. This allows the user to easily adjust the delay line\'s overall response. The DS1135LU-20+T&R can be programmed to provide delays ranging from 1 nanosecond to 1 second.

In conclusion, the DS1135LU-20+T&R is a versatile delay line which can be used in a wide range of clock and timing applications. Its programmable features make it an ideal choice for applications where precise timing is required. Its wide range of features also make it suitable for applications where signal buffering, equalization and filter shaping are required.
