Chapter 1: KCU1250 Board Features and Operation
More information about the power system components used on the KCU1250 board is
available from the Maxim Integrated InTune digital power website [Ref 5] .
MGT Transceiver Power Module
The KCU1250 board includes one MGT transceiver power module (callout 19, Figure 1-2 ).
The MGT power modules supply the MGTAVCC, MGTAVTT, and MGTVCCAUX power rails,
which connect to the FPGA MGT transceivers. MGT power modules from third-party vendors
are provided with the KCU1250 board for evaluation (Maxim Integrated MAXIM001 and
Texas Instruments PMP9463 [Ref 5] ). Either one of the modules can be plugged into J46 and
J124 on the outlined and labeled power module locations shown in Figure 1-5 .
Table 1-4 lists the nominal voltage values for MGTAVCC, MGTAVTT, and MGTVCCAUX power
rails. It also lists the maximum current rating for each rail supplied by MGT modules
included with the KCU1250 board.
The MGT transceiver power rails can also be supplied externally. The external supply
connectors are described in Table 1-3 .
CAUTION!
The MGT Power Module MUST be removed when providing external power to the MGT
transceiver rails.
Information about the available MGT power modules included with the KCU1250 board
characterization kit is available from the vendor websites [Ref 5] .
