61.5MHz
Clock in the transmit direction from the TLX-400
Thin Links AXI slave interface on the Juno r2
SoC.
The MCC uses the
board.txt
configuration file in the microSD card to set the frequency of the board
clock generators. You can adjust these default clock frequencies by editing this file. You can also adjust
the board clocks during runtime by using the SYS_CFG register interface.
The Juno r2 SoC has internal PLLs and clock generators that generate clocks to drive the Juno r2 SoC
internal systems.
