Description
The RTL8271B-GR is a single-port Phyceiver integrated circuit chip designed for use in various electronic systems. It is equipped with an MII (Media Independent Interface) and is capable of supporting 10/100M Ethernet Physical-layer functions. These functions include the Physical Coding Sublayer (PCS), Physical Medium Attachment (PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD), 10Base-Tx Encoder/Decoder, and Twisted Pair Media Access Unit (TPMAU). This chip is manufactured using an advanced CMOS process to ensure low voltage and power consumption. It can be utilized as a Network Interface Adapter, MAU, CNR, ACR, Ethernet Hub, or Ethernet Switch. Additionally, the RTL8271B-GR is compatible with any embedded system that requires a twisted pair physical connection to an Ethernet MAC.
