GB-Ethernet Front End
Reference Designs
GB-Ethernet Front End
- Based on Microchip's EVB-LAN7800LC evaluation board.
- Circuit built on a 4-layer PCB.
- Powered via the USB interface.
- Firmware enables real-time measurements of data rate and bit error rate.
- The electronics board offers two interfaces:
- USB Type C™ (USB 3.1)
- 1 Gigabit RJ45/Ethernet interface
GB PoE+ Ethernet-USB Adapter
GB PoE+ Ethernet-USB Adapter
- Based on the reference design of a 1 Gbit/s Ethernet USB adapter.
- Original design lacked PoE functionality.
- Incorporates Power over Ethernet Plus (PoE+) capability.
- GB PoE+ Ethernet USB Adapter offers three interfaces:
- USB Type-C (USB 3.1)
- RJ45 1 Gbit/s Ethernet interface with integrated PoE function
- Connector for a DC/DC converter with an adjustable output voltage of 6 to 18 V and a maximum output power of 25 W.
Basics of GB-Ethernet interface
Basics of GB-Ethernet interface
- Magnetics module (E.g., WE-LAN): This consists of a transformer and common mode choke (CMC). It reduces common-mode currents, which are unwanted electrical currents that flow in the same direction on both conductors of a twisted-pair cable. Common-mode currents can interfere with the differential signal carrying the data.
- Bob Smith termination: This termination circuit, which includes a capacitor and four resistors, is connected between the differential signal pairs and ground. It reduces susceptibility to interference from unused wires on the RJ45 connector by providing a path for common-mode currents to flow to ground.
Design structure of GB-Ethernet interface
Design structure of GB-Ethernet interface
The GB-Ethernet USB adapter was developed based on the EVBLAN7800LC Evaluation Board from Microchip. The board is available in two different variants: discrete and integrated. The integrated design combines the functionality of the discrete components into fewer, more streamlined modules. This integration results in a potentially more reliable design, reducing PCB space and simplifying assembly.
Discrete Solution Components
WE-LAN
A separate local area network transformer module.
WR-MJ
A discrete RJ45 Ethernet connector.
WE-TVS
Transient voltage suppressor.
Integrated Solution Components
WE-RJ45LAN
Integrates the RJ45 connector and the transformer (which includes the functions of WE-LAN and the WR-MJ).
WCAP-CSMH

Frequently asked questions
![Circuit, powered device and powered source]( "powered-device-powered-source-equipment")
- PSE (Power Source Equipment): This is the device that supplies power over the Ethernet cable. In a PoE system, a switch or injector acts as the PSE.
- PD (Powered Device): This is the device that receives power and data over the Ethernet cable. Examples of PoE-powered devices include IP cameras, VoIP phones and wireless access points.
