For UltraScale+ GTH and GTY, a power down feature is also added to individual PLLs (RX clock source and TX clock source). These PLLs can be individually set to power down mode to save power when they are not in use.

Note: There is no specific PLL power down mode in UltraScale. When the Operation Mode is set to Power Down, PLLs are also assumed to be powered down by default.
