Design Example
Transmit 3G-SDI Level A with Embedding of Audio Group 1, 2 and 3
To transmit the 3G-SDI Level A video standard, follow these steps:
1. Set DIP switch[2:1] = 11
2. The demonstration runs and the LEDs indicate the following conditions:
a. LED D6 and D7 indicate the internal video pattern generator signal standard.
b. LED D8 and D9 indicate the receive video standard.
c. LED D16 blinks indicating the heartbeat of the receiver's recovered clock.
d. LED D17 illuminates when the receiver is frame locked.
e. LED D18 illuminates when the receiver is TRS locked.
f. LED D19 illuminates when the receiver is alignment locked.
g. LED D23, D22 and D21 illuminate when the data packet of audio groups 1, 2
and 3 are detected in the incoming SDI stream.
Figure 4–13 shows the condition of the LEDs.
