Figure 6-4 shows typical biasing and LED connections for the ICS1893AF. Figure 6-4. ICS1893AF LED - PHY Interface ICS1893AF 10K Ω 86 4 3 1 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. Notes: 1. All LED pins must be set during reset. 2. Caution: PHY address 00 tri-states the MII interface. Don’t use PHY address 00. 3. For more reliable address capture during power-on reset, add a 10K Ω resistor across the LED. |
