Full Swing Crystal Oscillator
Table 7-4.
Notes:
This Crystal Oscillator is a full swing oscillator, with rail-to-rail swing on the XTAL2 output. This is
useful for driving other clock inputs and in noisy environments. The current consumption is
higher than the
Oscillator will only operate for Vcc = 2.7 to 5.5 volts.
Some initial guidelines for choosing capacitors for use with crystals are given in
crystal should be connected as described in
The operating mode is selected by the fuses CKSEL3..1 as shown in
Table 7-5.

quency of the device, and if frequency stability at start-up is not important for the application.
Fuse can be programmed in order to divide the internal frequency by 8. It must be ensured
that the resulting divided clock meets the frequency specification of the device.
