The SN65LVDS352PWRG4 is a low-voltage differential signaling (LVDS) transceiver, commonly used as an interface between two digital devices. This device features low-voltage operation, low EMI radiation, and wide margin differential and common-mode signal transmission. It is used in a variety of applications such as networking and multimedia applications, computer systems, and data-acquisition systems.

Application Field

The SN65LVDS352PWRG4 is designed for use in portable systems where space is at a premium and energy consumption is a priority, such as laptop and pocketPC computers. It is also well-suited for applications such as automotive instrumentation, and embedded systems. This device is compliant with LVDS specifications and supports data transfer rates up to 37 Mbps. It is also backward compatible with Low Voltage Positive Emitter Coupled Logic (LVPECL) and Low Voltage Transistor-Transistor Logic (LVTTL) logic families.

Working Principle

The SN65LVDS352PWRG4 utilizes low-voltage differential signaling (LVDS) technology their signals are transmitted via differential pairs of wires. This arrangement reduces susceptibility to electromagnetic interference, allowing more reliable signal transmission over greater distances, while consuming less power than traditional logic families. The SN65LVDS352PWRG4 contains 5 transmitters and 5 receivers in a very small 20-pin package. Each transmitter and receiver has one differential pair: one positive line and one negative line. The transmitted data is received by the receivers, interpreted, and then transmitted out of the device as LVTTL or LVPECL logic voltage levels. The SN65LVDS352PWRG4 also features a built in flow control which each device is able to interpret to prevent data loss due to buffer overruns or other data integrity issues.

The SN65LVDS352PWRG4 also has integrated hot swap and power down protection. This makes it ideal for use in systems that may require disconnecting and reconnecting devices mid-session. The device’s hot plug protection feature prevents any excess current from being drawn from the power source, limiting power losses and preventing data corruption due to variations in the power supply.

The SN65LVDS352PWRG4 is also capable of supporting a length up to 15 meters if LVDS grade cable is used. This makes the device well-suited for applications where the two devices interfacing are separated by long distances, such as automotive instrumentation or communications networks. Furthermore, it is designed for operating temperatures between -40 to +85 degrees Celsius, making it suitable for use in a wide variety of environments.

In summary, the SN65LVDS352PWRG4 is a very useful transceiver device that combines features including low-voltage operation, low EMI radiation, wide margin differential and common-mode signal transmission, and more. Its low-voltage differential signaling (LVDS) technology makes it ideal for use in portable systems where power consumption and distance are primary considerations, as well as in automotive and embedded applications.
