13 / 74 page  2007-2016 Microchip Technology Inc. DS00002260A-page 13 LAN8700/LAN8700i TABLE 3-8: POWER SIGNALS Signal Name Type Description VDDIO POWER +1.6V to +3.6V Variable I/O Pad Power VDD33 POWER +3.3V Core Regulator Input. VDDA3.3 POWER +3.3V Analog Power VDD_CORE POWER +1.8V (Core voltage) - 1.8V for digital circuitry on chip. Supplied by the on-chip regulator unless configured for regulator off mode using the RX_CLK/REGOFF pin. Place a 0.1uF capacitor near this pin and connect the capacitor from this pin to ground. When using the on-chip regulator, place a 4.7uF ±20% capacitor with ESR < 1ohm near this pin and connect the capacitor from this pin to ground. X5R or X7R ceramic capacitors are recommended since they exhibit an ESR lower than 0.1ohm at frequencies greater than 10kHz. VSS POWER Exposed Ground Flag. The flag must be connected to the ground plane with an array of vias as described in the Analog Layout Guidelines |
