Figure 4-4: CDU Clock Options - CAN
The S/PDIF clock is ideally programmed to operate at 200 MHz (out of the four options).
Figure 4-5: CDU Clock Options - S/PDIF
The Gigabit Ethernet clock should always be 125 MHz if GigE/RGMII is used. Program the CDU depending on
which CGU can provide 125 MHz.
Figure 4-6: CDU Clock Options Gigabit Ethernet
The link port can operate up to a maximum speed of 150 MHz. If the link port needs to operate close to 150 MHz,
then the link port clock can be selected from CGU1 to get maximum operation.
