Power Monitoring

To measure and view current power information for the transceiver signal integrity

development board, you need install the free LTpowerPlay™ software, and then

connect your PC and the development board to a Linear Technology DC1613A

USB-to-PMBus Controller. Both the software and the controller interface are available

from the Linear Technology (www.linear.com) website. Figure 6–9 shows the

LTpowerPlay GUI.

1 The DC1613A USB-to-PMBus controller communicates with the LTC

2978 on-board

octal PMBus power supply monitor and controller at the U10/11 board reference. For

more information on the LTC2978, refer to the Transceiver Signal Integrity Development

Kit Stratix V GX Reference Manual.

c The LTC 2978 power monitor devices installed on this board are programmed with a

project file that sets up each voltage rail according to a sequence. Each voltage rail will

adjust to its voltage level to within tolerance. However, if the development board is

powered off and powered on again with SW2 in the open position, the voltage rails

VCCRT_GXB and VCCA_GXB will not come up to the proper levels unless SW2-1

and SW2-2 are set to the default closed position at power up. For SW2 switch settings,

refer to the default settings in Table 4–1 on page 4–2.
