SN65LVDS95DGGREP

Introduction

The SN65LVDS95DGGRE is an integrated circuit (IC), also referred to as a chip, that provides a point-to-point interface between low voltage differential signaling (LVDS) buses and multiple processors or serial interfaces. It is one of several LVDS component solutions offered by Texas Instruments. In general, LVDS systems allow for high speed data transmission by utilizing differential signaling, while greatly reducing the power consumption. The SN65LVDS95DGGRE operates with a power supply voltage of 3.3 V and is capable of providing data rates up to 400 Mbps.

Application Field and Working Principle

Application Field

The SN65LVDS95DGGRE device is suitable for a variety of serial data-transfer applications requiring high data rates, low power consumption, and high noise immunity. This makes it a great solution for applications such as automotive infotainment networks, Ethernet network interface controllers, SATA/PATA node controllers, and more. This device is also suitable for applications with limited board space, thus saving on board space.

Working Principle

The basic operation of the SN65LVDS95DGGRE device is quite simple. The device consists of two main components: a transmitter and a receiver. The transmitter is responsible for taking raw data as an input, encoding it as LVDS data, and transmitting it over a differential pair. The receiver is responsible for receiving the encoded data, decoding it, and sending out the raw data. The differential pairs used in this device provide superior noise immunity because any noise that is picked up is “averaged out” by the differential receiver.

The SN65LVDS95DGGRE is designed to support up to 4.5GHz clock rates and operate with a single power supply of 3.3 V. The device also has several features to help protect against signal errors including parallel and register loopback, differential and common mode output voltage, and input signal skew compensation. Furthermore, the device is designed to have minimum jitter, making it ideal for high frequency LVDS applications.
