DS1135LZ-25+T&R is a delay line module developed and produced by Exar Corporation, which is a world-leading provider of analog and mixed-signal integrated circuits and chip solutions. This delay line module has the following features:

• The module, using a unique sub-circuit design, implements long operation delay (25 ns) with low power consumption and low noise operation (1.75 ns jitter at 1 Hz reference).

• Integrated LVDS (Low Voltage Differential Signal) line driver. The delay line module also provides integrated analog device driving capability, thereby simplifying board design and implementation.

• The designed input/output circuit is equipped with hysteresis comparator to ensure high-speed data integrity.

• The package is small and easy to use. The module contains an input circuit, a voltage-controlled delay line, a hysteresis output circuit and two clock inputs that allow the user to adjust delay difference between two signals.

DS1135LZ-25+T&R Application Field and Working Principle

The DS1135LZ-25+T&R is a precision Delay Line module, suitable for use in a wide range of clock/timing applications. It is ideally suited for delay equalization and low jitter time management applications in clock systems, communications and networking equipment. The module also provides integrated LVDS line driver and high-speed data integrity. It can be used in telecommunications/networking, computing, optical storage and LCD products.

The DS1135LZ-25+T&R technology is based on the phase locked loop (PLL) principle. It supports input frequency control, precise free-running delay control, and fast transient response. The module supports dual-frequency Clock input, and its output can be adjusted by the POWER pins. The delay line module contains two input circuits and two output circuits that allow the user to adjust delay difference between two signals.

The input circuit of the DS1135LZ-25+T&R uses a Schmitt trigger comparator with hysteresis. This provides improved noise immunity, faster rise and fall times, and faster settling times. The input buffer also supports an adjustable clocking system that allows the module to reduce jitter and improve noise immunity. The output stage is a low-noise low-power hysteresis differential amplifier for improved noise immunity and lower power dissipation.

The analog control circuit contains a voltage-controlled delay line, switchable dual-frequency inputs and adjustable POWER pins. The delay line is calibrated for minimum timing skew, and the module does not suffer from long term frequency drift. The input and output stages of the module have adjustable timing delays and preamplifiers for compatibility with different types of signals.

The DS1135LZ-25+T&R can be used in various applications such as tester instrumentation, broadcasting and transport equipment, clock and timing systems, communications networks, and seismic applications. The module is also suitable for use in automotive and industrial equipment, consumer electronics devices, and home networking solutions.

In conclusion, the DS1135LZ-25+T&R is an excellent delay line module for clock and timing applications, providing a high speed, low power, and low-noise design. It is suitable for a wide range of clock and timing applications, including tester instrumentation, broadcasting and transport equipment, and clock and timing systems. The module also supports high-speed data integrity and provides excellent jitter performances.
