External Clock Input Parameters
These parameters specify the external clock generation for the XC238xC. The clock can
be generated in two ways:
By connecting a crystal or ceramic resonator to pins XTAL1/XTAL2
By supplying an external clock signal
– This clock signal can be supplied either to pin XTAL1 (core voltage domain) or to
pin CLKIN1 or CLKIN2 (IO voltage domain)
If connected to CLKIN1 or CLKIN2, the input signal must reach the defined input levels
V
IL and VIH. If connected to XTAL1, a minimum amplitude VAX1 (peak-to-peak voltage) is
sufficient for the operation of the on-chip oscillator.
Note: The given clock timing parameters (
t
1 … t4) are only valid for an external clock
input signal.
Note: Operating Conditions apply.
