LTC4303IDD#TRPBF is an integrated, low-power differential signal line transceiver with an integrated 1:1 transformer driver and a user selectable AC/DC coupled 3-state differential line/bus receiver. This single-chip solution is designed to handle high voltage, bidirectional signals that are compliant with IEEE 802.3 using twisted pair Ethernet cabling. The LTC4303IDD#TRPBF supports low power control and bus signaling in systems such as industrial Ethernet, automotive Ethernet, and other aircraft control networks.The LTC4303IDD#TRPBF provides the necessary protection between controller and line and a low capacitance isolated interface for bidirectional communications. The LTC4303IDD#TRPBF features low bias current and low distortion transceiver drivers, which minimize power consumption and EMI, while maintaining excellent signal integrity. Additionally, the device supports up to 50V RMS DC-coupled and 25V AC-coupled differential line or bus receiver voltages.The LTC4303IDD#TRPBF is housed in an easy-to-use leadless 16-pin 1mm x 1.45mm LQFN package, making it suitable for a wide range of applications, including industrial Ethernet, automotive Ethernet, and aircraft control networks. Additionally, the device is rated for industrial temperature operation with a –40°C to +85°C ambient temperature range.The LTC4303IDD#TRPBF works on the principle of differential signaling, which is a process in which two signals are sent along a single pair of wires. The two signals are oppositely oriented, so when one is “high” the other is “low”. This makes it easier to separate the “high” and “low” signals, providing more reliable data and less susceptibility to noise.The LTC4303IDD#TRPBF offers 2:1 differential transceiver drivers and integrated 1:1 transformer drivers designed to protect the controller from high voltage stray or overshoot on the line as well as EMI. The receiver outputs feature user selectable AC or DC coupled 3-state differential line or bus receiver. The outputs of the signals can be anything from TTL or LVTTL to LVDS, LVPECL or CML. Additionally, the device supports up to 50V RMS DC-coupled or 25V AC-coupled differential line or bus receiver voltages.The LTC4303IDD#TRPBF also offers thermal protection on the input as well as an integrated overtemperature sensing circuit. The input pins are configured with a Schmitt trigger, allowing the device to offer good noise immunity, low output noise and good input pulse filtering.The LTC4303IDD#TRPBF’s small form factor allows the device to be used in many applications including industrial Ethernet, automotive Ethernet, and aircraft control networks. It is suitable for voltage-level translation applications, serving as a signal buffer, repeater, splitter or converter. The device\'s on-board transformer also isolates the incoming and outgoing signals, protects against stray current, and prevents EMI.In summary, the LTC4303IDD#TRPBF is an efficient and reliable low-power differential signal line transceiver with an integrated 1:1 transformer driver and a user selectable AC/DC coupled 3-state differential line/bus receiver. It is also protected against high voltage and EMI, and is rated for industrial temperature operation. Furthermore, the device’s small form factor makes it suitable for voltage-level translation applications such as signal buffering, repeating, splitting and conversion. Therefore, it is well-suited for a variety of applications, including industrial Ethernet, automotive Ethernet, and aircraft control networks.
