Smart Card Interface Detailed Description The DS8113 is an analog front-end for communicating with 1.8V, 3V, and 5V smart cards dual input- voltage device, requiring one supply to match that of a host microcontroller and a separate ...
Page 9
Clock Circuitry The card clock signal (CLK) is derived from a clock sig- nal input to XTAL1 or from a crystal operating 20MHz connected between XTAL1 and XTAL2. The output clock frequency of CLK is selectable through ...

Smart Card Power Select The DS8113 supports three smart card V 1.8V, 3V, and 5V. The power select is controlled by the 1_8V and 5V/3V signals as shown in Table 3. The 1_8V signal has priority over 5V/3V. When 1_8V ...
