8.3.4 Clock Division and Multiplexing

TCA5013 card interface modules all have a CLK pin that provide a clock signal that is used for smartcard operation. This clock signal is generated based on an internal oscillator or from the CLKIN1/CLKIN2 input clock signals, by the clock divider and multiplexer circuitry. The user card has a dedicated clock divider and multiplexer. The user card CLK output can be a configured to be a function of the CLKIN1 frequency or the internal oscillator frequency. CLKIN2 is shared by all the SAM card interface modules. The CLK output of each SAM card can be independently configured based on the CLKIN2 frequency or the internal oscillator frequency. CLK operation section describes the clock division and multiplexing in detail.
