ADM6996L

The ADM6996L integrates five 100Base-X physical sub-layer (PHY), 100Base-TX physical medium dependent (PMD) transceivers, five complete 10Base-T modules, 6 port 10/100 switch controller and one 10/100 MII/GPSI MAC and  emory into a single chip for both 10Mbits/s, 100Mbits/s Ethernet switch operation. It also supports 100Base-FX  peration through external fiber-optic transceivers. The device is capable of operating in either Full Duplex mode orHalf-Duplex mode in 10Mbits/s and 100Mbits/s. Operational modes can be selected by hardware configuration ins,software settings of management registers, or determined by the on-chip auto negotiation logic.

The ADM6996L consists of three major blocks:
• 10/100M PHY Block
• Switch Controller Block
• Built-in SSRAM

The interfaces used for communication between PHY block and switch core is MII interface.

Auto MDIX function is supported in this block. This function can be Enable/Disable by hardware pin.
