Interface - Drivers, Receivers, Transceivers

The SN75189NSR is a high performance, dual monolithic differential line driver intended to provide fast data transmission in long cables and multi-drop local area networks (LANs). It is suitable for all applications where a differential line driver is needed, such as pulse-coded modulations (PCM).

SN75189NSR Application Field

SN75189NSR is designed to meet the growing demands of today\'s LANs. It offers a reliable, high-performance cable driving solution for short-haul networks designed for data and voice communications. This driver can handle both unbalanced and balanced signals, and is suitable for use as a line driver for both point-to-point and multi-drop applications. It is especially useful for networks that require the transmission of data over long distances, where high-speed data rates are necessary to maintain reliable communications.

The SN75189NSR is commonly used in applications such as LANs, point-to-point networks, and PCM systems. In LAN applications, it can be used to drive twisted-pair Ethernet links. It can also be used as a line driver in PCM systems and in point-to-point systems using unbalanced or balanced signals. This driver can also be used to drive differential video signals over a long distance. It is also suitable for driving bus systems and fault-tolerant networks.

SN75189NSR Working Principle

The SN75189NSR is a dual monolithic differential line driver that uses low power semiconductor technology. It features a dual stage operation that allows it to be used as a line driver for both unbalanced and balanced signals. The driver consists of two stages, the receiving stage, and the output stage. The receiving stage takes in the incoming signal from the source and amplifies it. The output stage then takes the amplified input signal and drives it over the line.

The SN75189NSR features a dynamic power source injection (DPSI) technique that allows the driver to deliver a high dynamic range of performance. This innovative approach helps to reduce electromagnetic interference (EMI) generated from the driver. The driver also features output slew rate control (SRR) which enables the driver to deliver precise and accurate signals over long distances. This feature helps ensure that communications over the network remain reliable.

In addition to the DPSI and SRR features, the SN75189NSR also provides inputhysteresis, which reduces noise and optimizes performance. The driver also has an adjustable supply voltage, which helps to minimize power consumption when the device is not in use. This allows the driver to be used in applications where low power consumption and low noise are important.

The SN75189NSR is designed to provide reliable and high-quality performance in applications where a differential line driver is needed. It is suitable for a variety of applications, from LANs to PCM systems, and is capable of handling both unbalanced and balanced signals. It features several advanced features, such as DPSI, SRR and input hysteresis, to help ensure reliable communications over long distances.
