PLL
AT90USB82/162
Internal PLL for USB interface
“0011”, giving a division factor of 8 at start up. This feature should be used if the selected clock
source has a higher frequency than the maximum frequency of the device at the present operat-
ing conditions. Note that any value can be written to the CLKPS bits regardless of the CKDIV8
Fuse setting. The Application software must ensure that a sufficient division factor is chosen if
the selected clock source has a higher frequency than the maximum frequency of the device at
the present operating conditions. The device is shipped with the CKDIV8 Fuse programmed.
Table 6-9.
The PLL is used to generate internal high frequency (48 MHz) clock for USB interface, the PLL
input is generated from an external low-frequency (the crystal oscillator or external clock input
pin from XTAL1).
The internal PLL in AT90USB82/162 generates a clock frequency that is 6x multiplied from nom-
inally 8 MHz input. The source of the 8 MHz PLL input clock is the output of the internal PLL
clock prescaler that generates the 8 MHz.
