20 / 394 page ![]() 20 • AR8327/AR8327N Seven-port Gigabit Ethernet Switch Atheros Communications, Inc. 20 • June 2011 COMPANY CONFIDENTIAL NOTE: For a 2-layer PCB design, we strongly recommend the use of external power — 1.1V for AVDD and DVDD. This will reduce thermal effects. NOTE: For a four-layer PCB design, we strongly recommend the use of a reserve external power supply for AVDD and DVDD when using the internal switch regulator. The following table shows the interface summary relative to the AR8327’s different modes. VDD33 A6, A10, B15, A27, A33, A36, A42 p Analog 3.3V power input VDD25_REG A9 AO The 2.5V power output VDD25_IO B41, B46, A63, B73 p The 2.5V power source for IO pad AVDDVCO_O A12 OA Analog 1.25V power output for VCO AVDDVCO_I A34 P Analog 1.25V power input for VCO and connected to pin A12 FILCAP[0:7] A3, B12, B18, B19, A30, B31, A39 I Connect to an external capacitor 0.1uF for power stable. AVDD25 A11 Analog 2.5V input. Connect this pin to pin A9 and add 0.1uF capacitor to this pin. Table 1-2.
