Clock source

—Specifies the clock the SDI HSMC PLL locks to. The following

choices are available:

Lock to host

—Locks the SDI HSMC PLL to the local reference on the Stratix IV

GX FPGA development board.

Lock to input

—Locks the SDI HSMC PLL to the SDI input stream.

Intensity

—Specifies the color intensity of the transmitted color bar pattern.

SDI standard

—Specifies the video standard the pattern generator uses on the SDI

video stream. The following choices are available:

SD

—Specifies a 270 Mbps data rate

HD

—Specifies a 1.485 Gbps data rate

3G HD

—Specifies a 2.97 Gbps data rate

Receiver Status

These controls show the settings for each receiver channel on the SDI HSMC. Both
receiver channels (CH1 RX and CH2 RX) operate independently but must have the
same clock source or be synchronized with each other.

CH1 Rx status

and CH2 Rx status—Show the status of the following receiver

channel attributes:

Alignment

—Shows the alignment locked or unlocked state. "Locked" indicates

that the TRS pattern has been received and data is word aligned.

TRS

—Shows the TRS locked or unlocked state. "Locked" indicates the six TRS

patterns have been received with the same timing.

Frame

—Shows the frame locked or unlocked state. "Locked" indicates the

frame sync patterns have been received.

Standard

—Shows the type of video input (SD, HD, or 3G) the channel is

receiving.

The Power Monitor

The Power Monitor measures and reports current power and temperature
information for the board. To start the application, click Power Monitor in the Board
Test System application.

You can also run the Power Monitor as a stand-alone application. PowerMonitor.exe
resides in the dir>\kits\stratixIVGX_4sgx230_av\examples\board_test_system directory. On
Windows, click Start > All Programs > Altera > Audio Video Development Kit,
Stratix IV GX Edition

<version> > Power Monitor to start the application.

The Power Monitor communicates with the MAX II device on the board through the
JTAG bus. A power monitor circuit attached to the MAX II device allows you to
measure the power that the Stratix IV GX FPGA device is consuming regardless of the
design currently running.
