f For more information about the Si570, Si571, or Si5338 oscillators and the Stratix V GS
development board’s clocking circuitry and clock input pins, refer to the
DSP
Development Kit, Stratix V Edition Reference Manual .
The Clock Control communicates with the MAX V device on the board through the
JTAG bus. The Si570, Si571, Si5338 (U38, U46) programmable oscillators are connected
to the MAX V device through a 2-wire serial bus. Clock frequencies will return to the
default values after power cycling the board.
Figure 6–11 shows the Clock Control.
The following sections describe the Clock Control controls.
