Table 2–42 lists the power monitor devices component reference and manufacturing
information.
Power Distribution System
Figure 2–10 shows the power distribution system on the development board. The
VCCR_GTB , VCCT_GTB, and VCCL_GTB power rails are separated on the 28G transceivers
but are combined on the 12.5G transceivers.
