Figure 6-3 shows typical biasing and LED connections for the ICS1893. Figure 6-3. ICS1893 LED - PHY Address ICS1893 10K Ω 64 62 60 59 55 P4RD P3TD P2LI P1CL P0AC REC TRANS LINK ACTIVITY 10K Ω LED 1K Ω 10K Ω LED 1K Ω 10K Ω VDD COL LED 1K Ω 10K Ω This circuit decodes to PHY address = 1. Note: 1. All LED pins must be set during reset. 2. PHY address 00 tri-states the MII interface. 3. For more reliable address capture during power-on reset, add a 10K Ω resistor across the LED. |
