SN65LVELT22DR

The SN65LVELT22DR is a low-voltage differential signaling (LVDS) signal translator with an integrated 120Ω differential termination, designed for expanded system configurations. The signal translator provides optimized signal termination for better data interface communication over longer distances and improved signal integrity. It also eliminates the need for an external 120Ω termination and reduces signal reflections, which often cause EMI and noise. With a maximum data rate of 622 Mbps, the device offers excellent performance and excellent signal integrity. This makes it ideal for applications such as digital signage, industrial, medical and automotive.

The SN65LVELT22DR is a single-channel, low-voltage logic device, optimized for signal conversion and termination applications. It is specially designed for LVDS signal switching in communications, instrumentation and data networking applications. The device can operate in 1.8V to 5.5V and is compliant to the LVDS electrical specifications. This makes it suitable for point-to-point and star distributed data communications, as well as low-noise, high-gain applications.

The SN65LVELT22DR is targeted for applications dependent on reliable LVDS data communication. It provides the solution to achieve the reliability required in your communications system. It utilizes the open-drain architecture and is designed for use in applications such as low-noise, high-gain, serial communication and multi-channel LVDS systems, as well as digital signage and lighting applications. The device is designed for both single-ended-to-differential translation and differential-to-differential translation. It also supports multiple digital data rate configurations.

The SN65LVELT22DR works by passively conditioning the incoming data to eliminate signal reflections. It passes signals through an internal resistor-capacitor (RC) network, which guarantees a minimum signal bandwidth of 622 Mbps. This RC filtering also eliminates reflections on the transmission line by improving the signal characteristics. By providing a high-performance signal translator, the device eliminates the need for external termination resistors and reduces signal reflections, which can be a problem with long-distance data communications.

In addition to its internal 120Ω termination resistance, the SN65LVELT22DR also provides a complimentary logic output state. This circuit is used to provide a clean-up signal of any detected errors on the transmission line. It includes a data latch mechanism and a 3-state output buffer. This unique feature helps the user detect and identify any errors or noise pulses on the data line. In addition, the SN65LVELT22DR has built-in short-circuit protection to safeguard its output pins.

The SN65LVELT22DR is an ideal choice for applications where high-performance signal conditioning and termination are desired. Its single-channel capability makes it a cost-effective solution for low-voltage applications. Its low-voltage logic core has been designed to reliably switch between high and low voltage levels, and the integrated 120Ω termination circuitry gives maximum signal integrity and eliminates the need for external termination resistors. With its ability to support data rates up to 622 Mbps, the SN65LVELT22DR is an excellent choice for any application that requires reliable data communication.
