4:1 | xMII Impedance Control | RW | 1 000 | MAC Impedance Control:
MAC Impedance Control sets the series termination value within the DP83TC811S-Q1. This field controls the following pins: RX_D[3:0], RX_CLK, RX_ER, and RX_DV. 0 000 = 99 Ω 0 001 = 91 Ω 0 010 = 84 Ω 0 011 = 78 Ω 0 100 = 73 Ω 0 101 = 69 Ω 0 110 = 65 Ω 0 111 = 61 Ω 1 000 = 58 Ω (default) 1 001 = 55 Ω 1 010 = 53 Ω 1 011 = 50 Ω 1 100 = 48 Ω 1 101 = 46 Ω 1 110 = 44 Ω 1 111 = 42 Ω Note: Individual pin control is not supported. |
