Interface - Drivers, Receivers, Transceivers

The SN65LVDM179DGKR is a low-voltage differential signaling (LVDS) transceiver specially designed for the high-speed industry. This type of device provides a high-speed data transport system between electronic devices, and is very popular in the industrial market. This article will discuss the application field and working principle of the SN65LVDM179DGKR.

Application Field

The SN65LVDM179DGKR is an LVDS transceiver, meaning it can transfer data between two parts at up to 2.5Gb/s. This makes it an ideal device for applications that involve a high-speed data transfer. Furthermore, its small package size, low power consumption and low voltage makes it suitable for use in space-constrained systems.

The SN65LVDM179DGKR is widely used in industrial applications such as Factory Automation, Industrial Control, Sensors, Medical Equipment and LED Lighting.

Working Principle

The SN65LVDM179DGKR uses a differential signaling system to send and receive signals. This type of signaling is used to reduce the amount of noise in the signal and ensure its integrity. The device consists of two parts: the transmitter and the receiver.

The transmitter uses an open-drain output, meaning that the output of the device is constantly pulled to the ground. The transmitter is connected to the receiver via an LVDS differential pair. When the transmitter is given an input, it will toggle the output of the open-drain output, thus driving the differential pair. This will create a small voltage difference between the two lines, which will be detected by the receiver.

The receiver, on the other hand, uses a differently biased input to detect the voltage difference in the differential pair. This allows the device to detect the incoming signal and transfer it to the corresponding output.

In summary, the SN65LVDM179DGKR is an ideal device for applications that require a high-speed data transfer. With its low power consumption, small package size and differential signaling system, it can provide reliable data communication between electronic devices.
