shows the system block diagram of the AES. There are two AES channels on the
SDI-FMC Board. Each contains one TX channel and one RX Channel.
Figure 3-6 AES System Blok Diagram
The AES3 RX channel delivers a 75-Ω load termination with a return loss of 25 dB or more. The
signal is inputted through a 75-Ω BNC and terminated with a 75-Ω resistor to ground. The
unbalanced signal is then balanced through an isolation transformer. The differential signal output
from the transformer is biased and input to a RS422 transceiver. The output of the RS422
transceiver is a single-ended LVCMOS signal which is driven to the host board through the HSMC
connector.
