25.1.2 External Clock Oscillator
When an external clock oscillator is used, numerous parameters must be considered. They include absolute
frequency, frequency change over temperature, output rise and fall times, output levels and duty cycle.
The output clock should be connected directly (not AC coupled) to the OSCi input of the device, and the OSCo
output should be left open as shown in Figure 24 on page 91. XC is a buffered version of the 20 MHz input clock
connected to the internal circuitry.
