23 / 131 page  Functional Descriptions VMDS-10507 VSC8504-02 Datasheet Revision 4.2 12 3.2.1 SerDes MAC When connected to a SerDes MAC compliant to 1000BASE-X, the VSC8504-02 device provides data throughput at a rate of 1000 Mbps only; 10 Mbps and 100 Mbps rates are not supported. To configure the device for SerDes MAC mode, set register 19G, bits 15:14 = 0, and register 23, bit 12 = 1. The device also supports 1000BASE-X Clause 37 MAC-side autonegotiation and is enabled through register 16E3, bit 7. To configure the rest of the device for 1000 Mbps operation, select 1000BASE-T only by disabling the 10BASE-T/100BASE-TX advertisements in register 4. Figure 14 • SerDes MAC Interface 3.2.2 SGMII MAC When configured to detect and switch between 10BASE-T, 100BASE-T, and 1000BASE-T data rates, the VSC8504-02 device can be connected to an SGMII-compatible MAC. To configure the device for SGMII MAC mode, set register 19G, bits 15:14 = 00 and register 23, bit 12 = 0. In addition, set register 18G as desired. This device also supports SGMII MAC-side autonegotiation and is enabled through register 16E3, bit 7. Figure 15 • SGMII MAC Interface 3.2.3 QSGMII MAC The VSC8504-02 device supports a QSGMII MAC to convey four ports of network data and port speed between 10BASE-T, 100BASE-T, and 1000BASE-T data rates and operates in both half-duplex and full- duplex at all port speeds.The MAC interface protocol for each port within QSGMII can be either 1000BASE-X or SGMII, if the QSGMII MAC that the VSC8504-02 is connecting to supports this functionality. To configure the device for QSGMII MAC mode, set register 19G, bits 15:14 = 01.
