Using Both Center Left and Right PLLs
You can use both center left and right PLLs simultaneously to drive DPA-disabled
channels on upper and lower differential banks. Unlike DPA-enabled channels, the
center left and right PLLs can drive cross-banks. For example, the upper-center left
and right PLL can drive the lower differential bank at the same time the lower center
left and right PLL is driving the upper differential bank, and vice versa, as shown in
