Introduction

DS1135LU-25 is a high performance clock/timing delay line product developed by Dialog Semiconductor. This product is a non-volatile delay line, which is widely used in a variety of applications such as bounceless operation of switches, encoding/decoding of digital signals, and power saving for system power down modes. The product is suitable for applications where accurate timing is required.

Operating principle

The DS1135LU-25 works by delaying a clock or timing signal in order to extend or re-synchronize that signal with other information sources. The delay line works by injecting a set number of pulses into the incoming signal. This delay can be controlled by a digital register and can range from 0 to 63 cycles with a resolution of as little as 0.03 cycles. The delay line is capable of providing a significant phase-jitter attenuation, up to a maximum of -93 dBc. This feature can provide a stable and accurate delay even in hostile environments or noisy systems.

Features

The DS1135LU-25 features a wide range of features and advantages. The product\'s design attributes include low-noise operation, low-power consumption, and a versatile architecture. It has an operating temperature of -40°C to 85°C, a 2mm×2mm QFN package, 1.8V and 3.3V compatibility, and support for programmable clock frequency. The device also offers an adjustable pulse width and a fixed output pulse duty cycle. The device can be programmed with a simple serial interface, and has a wide range of timing configurations, including adjustable duty cycle, adjustable pulse width, and adjustable delay.

Applications

The DS1135LU-25 is suitable for a wide range of applications where accurate timing is paramount. It is ideal for applications such as bounceless switches, power management & sequencing, regulating clock frequency, and pulse width & duty cycle control. The product is also suited for use in high-speed digital systems, where the need for precise timing control is especially important. The device can also be used in automotive applications, where the need for low-power and low-noise performance is critical for operational reliability.

Conclusion

The DS1135LU-25 is a versatile, high performance clock and timing delay line product designed for applications where accurate timing is required. With its wide range of features and advantages, the product is suitable for a variety of applications, from bounceless switch operation and power management & sequencing to high-speed digital systems and automotive applications. The device\'s unique architecture and design attributes offer low-noise and low-power performance, as well as adjustable pulse width and duty cycle. Thanks to its adjustable delay and phase-jitter attenuation, it can provide reliable and accurate timing in hostile environments.
