Internal Internal Pin Name Type Pin Name Type PU/PD PU/PD TXD_3 IO PD RX_ER IO PU TX_EN IO PD COL IO PU INT/PWDN IO PU RXD_0 IO PD LED_ACT IO PU RXD_1 IO PD LED_SPEED IO PU RXD_2 IO PD LED_LINK IO PU RXD_3 IO PD MDIO IO TX_CLK O RX_DV IO PD CLK25MHz_OUT O CRS IO PU RX_CLK O 3.4 Auto-Negotiation The TLK111 device auto-negotiates to operate in 10Base-T or 100Base-TX. With Auto-Negotiation enabled, the TLK111 negotiates with the link partner to determine the speed and duplex mode. If the link partner cannot Auto-Negotiate, the TLK111 device enters parallel-detect mode to determine the speed of the link partner. Parallel-detect mode uses fixed half-duplex mode. The TLK111 supports four different Ethernet protocols (10Mbs Half-Duplex, 10Mbs Full-Duplex, 100Mbs Half-Duplex, and 100Mbs Full-Duplex). Auto-Negotiation selects the highest performance protocol based on the advertised ability of the Link Partner. Control the Auto-Negotiation function within the TLK111 by: 1. Internal register access, or 2. Configuring the AN_EN, AN_1 and AN_0 pins The state of the AN_EN, AN_0 and AN_1 pins determine whether the TLK111 is forced into a specific mode, or if Auto-Negotiation advertises a specific ability (or set of abilities) as given in Table 3-1. These pins allow configuration options to be selected without requiring internal register access. The state of AN_EN, AN_0 and AN_1, upon power-up/reset, determines the state of bits [8:5] of the ANAR register (0x04h). Internal register access controls the Auto-Negotiation function, as defined by the IEEE 802.3u specification. For further detail regarding Auto-Negotiation, see Clause 28 of the IEEE 802.3u specification. Table 3-1. Auto-Negotiation Modes AN_EN AN_1 AN_0 Forced Mode 0 0 0 10Base-T, Half-Duplex 0 0 1 10Base-T, Full-Duplex 0 1 0 100Base-TX, Half-Duplex 0 1 1 100Base-TX, Full-Duplex AN_EN AN_1 AN_0 Advertised Mode 1 0 0 10Base-T, Half or Full-Duplex 1 0 1 100Base-TX, Half or Full-Duplex 1 1 0 10Base-T, Half Duplex 100Base-TX, Half Duplex 1 1 1 10Base-T, Half or Full-Duplex 100Base-TX, Half or Full-Duplex 12 Hardware Configuration Copyright © 2013–2014, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TLK111 |
