5 / 29 page  RTL8201BL 2002-03-29 Rev.1.2 5 5. Pin Description LI: Latched Input in power up or reset I/O: Bi-directional input and output I: Input O: Output P: Power 5.1 100 Mbps MII & PCS Interface Symbol Type Pin No. Description TXC O 7 Transmit Clock: This pin provides a continuous clock as a timing reference for TXD[3:0] and TXEN. TXEN I 2 Transmit Enable: The input signal indicates the presence of a valid nibble data on TXD[3:0]. TXD[3:0] I 3, 4, 5, 6 Transmit Data: MAC will source TXD[0..3] synchronous with TXC when TXEN is asserted. RXC O 16 Receive Clock: This pin provides a continuous clock reference for RXDV and RXD[0..3] signals. RXC is 25MHz in the 100Mbps mode and 2.5Mhz in the 10Mbps mode. COL O 1 Collision Detected: COL is asserted high when a collision is detected on the media. CRS O 23 Carrier Sense: This pin’s signal is asserted high if the media is not in IDEL state. RXDV O 22 Receive Data Valid: This pin’s signal is asserted high when received data is present on the RXD[3:0] lines; the signal is deasserted at the end of the packet. The signal is valid on the rising of the RXC. RXD[3:0] O 18, 19, 20, 21 Receive Data: These are the four parallel receive data lines aligned on the nibble boundaries driven synchronously to the RXC for reception by the external physical unit (PHY). RXER/ FXEN O/LI 24 Receive error: if any 5B decode error occurs, such as invalid J/K, T/R, invalid symbol, this pin will go high. Fiber/UTP Enable: During power on reset, this pin status is latched to determine at which media mode to operate: 1: Fiber mode 0: UTP mode An internal weak pull low resistor, sets this to the default of UTP mode. It is possible to use an external 5.1KΩ pull high resistor to enable fiber mode. After power on, the pin operates as the Receive Error pin. MDC I 25 Management Data Clock: This pin provides a clock synchronous to MDIO, which may be asynchronous to the transmit TXC and receive RXC clocks. The clock rate can be up to 2.5MHz. MDIO I/O 26 Management Data Input/Output: This pin provides the bi-directional signal used to transfer management information. 5.2 SNI (Serial Network Interface): 10Mbps only Symbol Type Pin No. Description COL O 1 Collision Detect RXD0 O 21 Received Serial Data CRS O 23 Carrier Sense RXC O 16 Receive Clock: Resolved from received data TXD0 I 6 Transmit Serial Data TXC O 7 Transmit Clock: Generate by PHY TXEN I 2 Transmit Enable: For MAC to indicate transmit operation |
