LINK LAYER TO PHYSICAL LAYER (PHY) SERIAL INTERFACE |
摘要 |
A link layer to physical layer (PHY) serial interface is disclosed. In one aspect, a system on a chip (SoC) integrated circuit (IC) includes a link layer circuit, and a remote IC includes a Universal Serial Bus (USB) PHY circuit. A bus having four or fewer wires connects the two ICs. A link bridge communicates with the link layer circuit and serializes USB Transceiver Macrocell Interface (UTMI) signaling received from the link layer circuit as high speed (HS) USB messages for transmission to the remote IC. The link bridge also receives HS messages from the USB PHY circuit on the remote IC. The link bridge deserializes the HS messages to extract UTMI signaling and passes the extracted UTMI signaling to the link layer circuit. |
