BroadR-Reach click PID MIKROE-2796 Weight 26 g BroadR-Reach click brings the industry grade communication standard to the mikroBUS , which is built to be used in an Ethernet-based open network. The click board is equipped with the BCM54811 Transceiver from Broadcom Limited, which is used to provide the hardware PHY layer for the network, and the W3150A+ from WizNet, a hardware LSI protocol stack, that provides an easy and low-cost solution for high-speed Internet connectivity for digital devices by allowing simple installation of TCP/IP stack in the hardware. point-to-point Ethernet PHY technology was developed by Broadcom Limited. technology is a robust Ethernet physical layer interface, designed for use in noisy environments and harsh conditions, such as in industrial networking applications.

BroadR-Reach click uses the physical layer IC, also known as the PHY, labeled as BCM54811 and produced by Broadcom.

BroadR-Reach click has been designed to demonstrate and test 10 Mbps BroadR-Reach and 100 Mbps BroadR-Reach connectivity.

In addition to 10Mbps and 100Mbps BroadR-Reach connectivity, the transceiver can support 1000BASE-T, 100BASE-TX and 10BASE-T on standard Category 5 UTP cable. The 10BASE-T Ethernet can also run on standard categories 3, 4, and 5 UTP. The BCM54811 is designed to exceed IEEE specifications for noise cancellation and transmission jitter, providing consistent and reliable operation over the broadest range of existing cable infrastructures. Depending on the cable type used, it can reach up to 300m at 100Mbps or 500m at 10Mbps.
