The SN65LBC176AQDREP is a high-performance differential line transceiver designed for communication in both Local Area Networks (LANs) and in serial communication system applications. It is often used to establish communication between two or more devices over a relatively short distance. The SN65LBC176AQDREP provides a complete low-power differential line transceiver solution that operates at speeds up to 200 Mbps in both full-duplex and half-duplex modes at signalling rates of up to 400 Mbps. It is designed to support 8-bit to 10-bit communication data rates and is compliant with IEC/ISO 61158-2-2001, IEC/ISO 11442-3-2003, IEEE 802.3-2008, and other related standards. In addition, the transceiver operates at temperatures ranging from -40°C to +125°C.

This transceiver takes differential signals as an input and provides differential outputs suitable for driving twisted-pair cables over distances for up to 200 ft at data rates up to 400 Mbps. It also supports open-loop and start-stop operations, idle state recognition, auto-correlation acknowledgement/control, and other functions. The device provides adjustable saturation characteristics, enabling driving up to 10 twisted-pair connections without loss of signal quality due to crosstalk on the same cable. It can also be used in multi-master implementations, where multiple devices can communicate with each other, and in point-to-point and bus configurations.

The SN65LBC176AQDREP operates at 1.8 V to 5.5 V and includes an internal auto-resettable thermal shutdown feature, which helps protect the device from damage caused by excessive power supply rapid changes and electrical overstress. Furthermore, the transceiver is designed with a selectable active power management, allowing the device to maintain low current consumption when it is not actively transmitting or receiving data. This feature helps conserve energy and extends battery life in applications that require long-term unattended operation.

The SN65LBC176AQDREP is based on a differential line receiver and differential line driver topology. Its features include adjustable current limit, drive slew rate control, and programmable output rise and fall times. The device consists of two independent, fully differential line transceiver circuits that provide low-level, low-distortion and controlled-impedance transmissions. This transceiver also includes a three-level output kill indicator that can be used to quickly and reliably detect undervoltage/overvoltage conditions of a load on the differential lines. In addition, the device includes programmable hysteresis on the receiver inputs that improves reliability of communications.

The SN65LBC176AQDREP is suitable for a wide range of industrial and embedded applications including: communication interface controllers, Ethernet data communications, industrial control systems, USB and 1394A data communications, automotive networks, and embedded systems-on-chip (SOC). The device is available in a range of industry-standard packages such as TQFN, LQFN, and SOIC.
