DS275N Datasheet/PDFThe DS275N is a high-speed differential line driver for high-frequency and high-performance data transmission applications. It is able to drive small to large capacitive and resistive loads, as well as large loads with low power. With up to 8 bit resolution and internal fault current limiting, and shutdown protection, this driver is suitable for a wide range of applications. The performance and features make the DS275N a perfect choice for high-speed, low-power, and reliable data communication.
Application Field
The DS275N is ideal for a wide variety of applications including consumer and industrial audio and video, notebooks and computers, point-to-point and broadcast communications, automotive and Ethernet systems, audio and video streaming, spread spectrum communication, and wide-band applications. It is particularly useful for applications that require both high data rates and precise timing, such as infotainment systems, HDTVs, and home theaters. It can also be used in conjunction with other high-frequency components, such as transceivers, receivers, and other line drivers, to provide a complete solution for a variety of data communication needs.
Working Principle
The DS275N uses a differential, common-mode-operated, three-stage line-driver topology to drive single-ended or differential-input signals up to 2.5V, using 8-bit pseudo-dynamic digital-to-analog converters. This topology is known to have excellent power efficiency, low EMI, better noise immunity, and improved bandwidth compared to traditional line drivers. The digital step functions can be generated from a microcontroller or other digital interface. The driver is designed to drive up to 100Ω loads, although it can handle higher loads in some cases. The driver is able to drive small to large capacitive and resistive loads, as well as large loads with low power. It can also help to reduce EMI and increase system longevity.
The driver features an internal fault current limiting and shutdown protection, which can shut down the driver in the event of a system fault, protecting the system from possible damage. There are two forms of protection available: the fault current limiter, which prevents the driver from being damaged by excessive current, and the shutdown mode, which mitigates the effects of a system fault on the data line by forcing the output of the driver to zero.
The driver also features a configurable impedance per bit, which allows the user to adjust the line impedance depending on the characteristics of the system. This allows the user to tailor the performance to their requirements. The driver also features adjustable values for slew rate and current slew rate, which can be adjusted to suit the needs of the application.
