3 / 22 page DM9081 Final 3 Version: DM9081-DS-F01 April 22, 1997 Features T Repeater functions comply with IEEE 802.3 Repeater Unit specification T Eight Integral 10BASE-T transceivers utilize the required pre-distortion transmission technique T Two Attachment Unit Interface (AUI) ports allow connection with 10BASE5 (Ethernet) and 10BASE2 (Cheapernet) networks T Design a Dumb Hub in minimum mode by using minimum external logic that can respond to Link, Carrier Sense and Collision Status from LED T Supports one LED output per port for additional status indicators such as Link, Partition, Carrier Sense, etc. T Built-in Jabber LED reports global Jabber information of the DM9081 Hub T Built-in Traffic LED indicates Hub global 10MHz bandwidth utilization status T Expandable to accommodate two DM9081 connections, with no external logic required T On board PLL, Manchester encoder/decoder and FIFO T Expandable to accommodate increased number of repeater ports. Recommended IC cascade number: under 3 and inclusive T Preamble loss effects eliminated by deep FIFO T Each port can be isolated (partitioned) and reconnected separately T Twisted Pair Link Test capability T Full amplitude and timing regeneration for retransmitted signals T Low power CMOS process with single 5V supply T 100-pin QFP package Pin Configuration DTPO3- TPO3- DV DD DV DD LI/RX7 LI/RX6 LI/RX5 LI/RX4 DV DD LI/RX3 LI/RX1 LI/RX0 LI/RX2 AUI1_CRS_LED X1 COL_LED RESET# TESTPIN1 TESTPIN0 DGND EXPIN# DAT EXPOUT# TCK NC X2 NC DV DD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 28 30 27 29 80 79 78 77 76 75 74 72 73 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 CDP2 CDN2 RXP2 RXN2 TXP2 TXN2 CDP1 CDN1 RXP1 AGND RXD0- RXD1+ RXD2- RXD3+ RXD3- RXD4+ RXD4- RXD5+ RXD5- RXD6+ RXD6- RXD7+ RXD7- DM9081F DGND AUI1_CRS_LED RXD2+ RXD1- RXD0+ AV DD TXN1 TXP1 RXN1 LED_LATCH AUI_LED TP_BIT_LED TP_POL_LED TP_JAB_LED TRAFFIC_LED TP_PAR_LED TP_LINK_LED |
