13 / 149 page ![]() W6100 – Hardwired Dual TCP/IP Stack Controller 13/149 1.1 PIN Description Table 2 PIN Description PIN # Symbol Type Description 1 GNDA AP Analog Ground 2 TXON AO Differential Transmitted Signal Pair Data is transmitted to Media in TXOP/TXON differential signal pair on MDI Mode. 3 TXOP AO 4 1V2A AP Analog 1.2V Power 1V2O(PIN14) voltage source must be supplied back to this pin. 5 RXIN AI Differential Received Signal Pair Data is received from Media in RXIP/RXIN differential signal pair on MDI Mode. 6 RXIP AI 7 GNDA AP Analog Ground 8 3V3A AP Analog 3.3V Power 9 RSET_BG AO Off-chip Bias Resistor Must be connected to Analog Ground through external 12.3KΩ, tolerance rate 1% Resistance. 10 GND AP Digital Ground 11 XSCO AO 25MHz Clock Connect 25MHz Crystal Oscillator (XTAL) or Oscillator (OSC) for internal operation clock (SYS_CLK). W6100 can convert it to 25MHz or 100MHz and uses the converted clock as SYS_CLK. In normal mode, SYS_CLK is 100MHz. In low frequency mode, SYS_CLK is 25MHz * CAUTION If OSC is used, 25MHz@1.2V must be used and only XSCI must be connected and XSCO must be floated. ref) “Clock Selection Guide”, same as W5100S 12 XSCI AI 13 1V2D P Digital 1.2V Power 1V2O voltage source must be supplied to this pin. 14 1V2O PO Internal Regulator 1.2V Power Output Power which Internal Regulator of W6100 supplies. It supports Max 150mA. |
