14 / 142 page  LAN9220 DS00002417A-page 14 2006-2017 Microchip Technology Inc. 2.2 External Pull-Up/Pull-Down Resistors As detailed in Table 2-6, when using an external pull-up or pull-down resistor, the required value is dependent on the operating voltage. Usage of recommended pull-up/pull-down resistor values is required to ensure proper operation. 2.3 Buffer Types Note 2-1 Sink and source capabilities are dependent on the VDDVARIO voltage. Refer to Section 7.6, "DC Electrical Specifications" for additional information. Note 2-2 When operating at reduced VDDVARIO voltage levels (less than 3.0V), do not rely on internal pull- up and pull-down resistors to determine signal state. Refer to Section 2.2, "External Pull-Up/Pull- Down Resistors" and the individual signal descriptions in Section 2.1, "Pin List" for more information. TABLE 2-6: EXTERNAL PULL-UP/PULL-DOWN RESISTOR VALUES I/O Voltage Pull-Up/Pull-Down Resistor Value (Ohms) 3.3V +/- 300mV 10K 2.5 +/- 10% 7.5K 1.8V +/- 10% 4.7K TABLE 2-7: BUFFER TYPES Type Description VIS Variable voltage input pin VO12 Variable voltage output with 12mA sink and 12mA source (Note 2-1) VOD12 Variable voltage open-drain output with 12mA sink (Note 2-1) VO8 Variable voltage output 8mA symmetrical drive (Note 2-1) VOD8 Variable voltage open-drain output with 8 mA sink (Note 2-1) PU 50uA (typical) internal pull-up (Note 2-2) PD 50uA (typical) internal pull-down (Note 2-2) AI Analog input AO Analog output AIO Analog bi-directional ICLK Crystal oscillator input pin OCLK Crystal oscillator output pin |
