Description

The CS8904 combines four 10BASE-T Ethernet ENDECs and transceivers into a single low-cost device. Complete on-chip 10BASE-T Transceivers and filters eliminate external components, saving valuable board space and reducing cost. The CS8904 offers maximum design flexibility by providing individual control and status lines for each of the four interface ports.

The CS8904 supports full-duplex operation, allowing simultaneous transmission and reception on all ports. Auto-negotiation allows the automatic selection of either half or full duplex operation on a per-port basis.

The CS8904 is ideally suited for cost-sensitive Ethernet switch designs. With the CS8904, engineers can design a four-port Ethernet Transceiver circuit that occupies less than 1.0 square inch (6.5 sq. cm) of space, exclusive of transformers and RJ-45 connectors.
