BYW178-TAP

BYW178-TAP is a single receiver and transmitter designed for D-PD₂ communication systems over copper pairs according to IEEE802.3. It supports both twisted pair and screened pair media and provides up to 1Gbps in operation mode. The transmitter output is electronically adjustable from 100 Mbps up to 1000 Mbps, whereas the receiver input ranges from 800Mbps up to 1000 Mbps. The differential transmission pair operates at a frequency of up to 12GHz. This makes it possible to send data over distances up to 7.5m with 5Gbps and 10m with 2.5Gbps.

Its applications include baseband systems, audio-visual services, digital telecom and datacom systems. Its robustness and flexibility make it the ideal choice for a wide range of industrial Ethernet and communication applications, such as in industrial automation,intelligent transport systems, security systems, machine vision and energy management systems. BYW178-TAP offers the possibility of powering the device over the twisted pair.

This device is primarily used to transmit and receive data, as well as for signaling. By using the differential transmission pair, it is able to keep the data transmission robust even in cases of high interference or electromagnetic noise. It is designed to be able to run in normal, low-power and full-power modes. The device supports both master and slave modes in order to facilitate full half-duplex communication.

The BYW178-TAP works with a single-ended current drive scheme. The driver generates a differential signal with a centre-tapped output current. This is then amplified through the use of fixed gain amplification or powered gain with adjustable gain enabled. On the receiver side, the signal is detected and converted by a pair of comparators. The transmitters and receivers are internally synchronized. The device also features multiple protection capabilities including ESD protection, short-circuit withstand and over current protection.

The BYW178-TAP is a cost-effective and reliable solution for industrial networks and communication applications. Its capabilities and protections make it the ideal choice for a range of Ethernet and communication applications in industrial automation, intelligent transport systems, security systems, machine vision, and energy management systems.
