9 / 73 page xr XR17D158 REV. 1.2.2 UNIVERSAL (3.3V AND 5V) PCI BUS OCTAL UART 9 1.0 APPLICATION EXAMPLES The XR17D158 is designed to operate with VCC (voltage to the UART Core Logic) at 5V only, irrespective of whether the PCI bus is at 3.3V or 5V. Table 1 below shows the valid combinations of VCC and the PCI Bus Voltage, VIO that can be used for the device.. A typical application for a universal add-in card (VCC must be 5V) is shown in Figure 3. In an embedded system, the designer must still choose 5V power supply for the VCC regardless of VIO (3.3 or 5V). In Figure 4, examples 1 and 2 show valid applications of the XR17D158 in an embedded system. TABLE 1: VALID COMBINATIONS OF VCC AND VIO SUPPLY VOLTAGES VCC VIO 5.0V 5.0V Valid 5.0V 3.3V Valid 3.3V 5.0V Invalid 3.3V 3.3V Invalid FIGURE 3. TYPICAL APPLICATION FOR A UNIVERSAL ADD-IN CARD PCI Local Bus Interface UART Channel 7 UART Channel 6 UART Channel 5 UART Channel 4 UART Channel 3 UART Channel 2 UART Channel 1 UART Channel 0 UART Core Logic VCC = 5V VIO (3.3V or 5V) CLK (up to 33.34 MHz) Max Crystal Frequency = 24MHz Max External Clock = 50MHz |
