Chapter 1: VC7203 Board Features and Operation
Using External Power Sources
Callout 18, Figure 1-2
Each voltage rail for the FPGA logic and GTX transceivers has an associated jack (or jacks)
that can be used to provide power from an external source (Table 1-3). The jacks are
binding posts that accept standard banana plugs.
Caution!
Do NOT apply power to any of the FPGA logic power supply jacks without first disabling
the associated regulator or regulators. Failing to disable the regulator can damage the board.
Each onboard FPGA Logic regulator can be disabled by using its respective Power
Regulation jumper (callout 17, Figure 1-2) shown in Table 1-3. A regulator is disabled by
moving its Power Regulation jumper from POR_B to RESET.
Default Jumper and Switch Positions
A list of jumpers and switches and their required positions for normal board operation is
provided in Appendix A, Default Jumper Settings.
Monitoring Voltage and Current
Voltage and current monitoring and control are available for FPGA logic and transceiver
power rails through Texas Instruments' Fusion Digital Power graphical user interface
(GUI). The three onboard TI power controllers (U9 at PMBUS address 52, U10 at PMBUS
address 53, and U11 at PMBUS address 54) are wired to the same PMBus. The PMBus
connector, J26 (callout 20, Figure 1-2), is provided for use with the TI USB Interface
Adapter PMBus pod and associated TI GUI.
