The ADM485JRZ-REEL is an integrated physical layer device for high-speed, full-duplex data communication featuring low power, low electromagnetic interference and low heat dissipation. It is used in many industrial and commercial applications, typically as an interface between the physical (electrical) and the logical (data) layers of the communication protocol stack. It features a differential line driver, a differential line receiver, a reference voltage source, and a logic interface to external controllers.The device utilizes Miller capacitance to reduce the crosstalk from adjacent channels. The receiver is equipped with a programmable threshold to adjust the input sensitivity while the power down mode is utilized to reduce power consumption when data communication is not required. Moreover, the echo cancellation function can be enabled to eliminate the echo effect generated by the reflective events.The ADM485JRZ-REEL allows a data rate of up to 35Mbps, making it suitable for applications where large amounts of data need to be quickly transmitted and received. It provides a relatively low transmission power, which is suitable for low-cost communication links. It is also designed to be electrically compatible with RS-485 drivers, receivers, and transceivers which are used in other communication protocols and is compatible with voltage control interfaces which allow external controllers to reduce power consumption.The ADM485JRZ-REEL is an ideal solution for applications demanding low power, low crosstalk, and a reliable, full-duplex data link. It is well-suited for applications in industrial automation, factory automation, security systems, point-of-sale (POS) systems, and robotics. Additionally, the device is capable of supporting multiple drivers and receivers on the same line, allowing it to be utilized in multi-drop topology. The working principle of the ADM485JRZ-REEL is based on differential line drivers and receivers. These drivers and receivers work together in order to transmit and receive data on the transmitting and receiving lines, respectively. Each driver is connected to a pair of output terminals on the device\'s integrated circuit (IC) where the data is converted from digital to analog format before it is transmitted on the differential line. At the receiver end, the data is then received through the differential line, converted back from analog to digital format, and ultimately transmitted to the logic interface where it is interpreted by the external controller.The ADM485JRZ-REEL also provides a reference voltage source to the transmitter and receiver, allowing them to compare their signals and determine data validity. The reference voltage source also helps to reduce electrical noise generated by other sources by providing a reference voltage to the receivers.In conclusion, the ADM485JRZ-REEL is an ideal solution for high-speed, reliable, full-duplex data communication. Its low power consumption, low crosstalk, and compatibility with multiple drivers and receivers makes it well-suited for applications in industrial automation, factory automation, point-of-sale (POS) systems, and robotics.
