and
Figure 7
.
Clock Signals
The ADSP-21266 can use an external clock or a crystal. See
CLKIN pin description. The programmer can configure the
ADSP-21266 to use its internal clock generator by connecting
the necessary components to CLKIN and XTAL.
Figure 8
shows
the component connections used for a crystal operating in fun-
damental mode. Note that the 200 MHz clock rate is achieved
using a 12.5 MHz crystal and a PLL multiplier ratio 16:1
(CCLK:CLKIN).
