7 / 68 page DM9008 ISA/Plug & Play Super Ethernet Contoller Final 7 Version: DM9008-DS-F02 November 30, 2000 Pin Description (continued) Pin No. Symbol I/O Description NETWORK INTERFACE PINS 39 40 RX- RX+ I RECEIVE INPUT: Differential receive input pair from the transceiver 41 42 CD- CD+ I COLLISION INPUT: Differential collision input pair from the transceiver 50 49 TPTX+ TPTX- O TP Driver Outputs. These two outputs provide the TP drivers with pre-distortion capability 46 45 TPRX+ TPRX- I TP Receive Input. A differential receiver tie to the receive transformer pair of the twisted-pair wire. The receive pair of the twisted-pair medium is driven with 10 Mbits/s Manchester-encoded data 5 LILED OPEN DRAIN LINK and Traffic LED Driver: If TP is LINK-pass, this pin outputs low. This pin will go low for 80ms and then into high impedance state for 50ms to indicate the presence of traffic on the network 76 NC No connection POWER SUPPLY PINS 36, 47, 48 AVCC +5V DC power supply for analog CKT. A decoupling capacitor should be connected between these pins and GND for analog CKT 43, 44, 51 AGND GND for analog CKT 1, 53, 72 VCC +5V DC power supply for digital CKT. A decoupling capacitor should be connected between these pins and GND for digital CKT 52, 73, 74, 75, 100 GND GND for digital CKT |
