AX88772
USB to 10/100 Fast Ethernet/HomePNA Controller
3.9 MAC to MAC Connection via MII Interface
Below figure shows recommended MAC-to-MAC connection for AX88772 MII Interfacing with an external Ethernet
MAC device. When operating at this mode, the Ethernet MAC on both sides should be set to operate at 100M full-duplex
mode.
The U1 & R1 are reserved for adjusting RXDV/RXD[3:0] input setup/hold time with respect to AX88772 RX_CLK
clock phase. Either R2 or R1 is installed at a time. User should check the TX_CLK, TXD[3:0], TXEN output timing of
external Ethernet MAC device vs. AX88772’s RXDV/RXD[3:0] input setup/hold time.
The U2 & R3 are reserved for adjusting RXDV/RXD[3:0] input setup/hold time with respect to RX_CLK clock phase on
external Ethernet MAC device. Either R3 or R4 is installed at a time. User should check the TX_CLK, TXD[3:0], TXEN
output timing of AX88772 vs. the RXDV/RXD[3:0] setup/hold time of external Ethernet MAC device.
