Chapter 1: VC7203 Board Features and Operation

Using External Power Sources

Callout 18,
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
binding posts that accept standard banana plugs.
Caution!
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,
moving its Power Regulation jumper from POR_B to RESET.
Table 1-3: FPGA Logic and GTX Transceiver Rails
Notes:
1. The GTX power module must be removed before providing external power to any of the transceiver

Default Jumper and Switch Positions

A list of jumpers and switches and their required positions for normal board operation is
provided in

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,
Adapter PMBus pod and associated TI GUI.
