4.4 Analog output channels
The FMC204 has four single-ended analog outputs that are AC-coupled from the D/A device.
An RF transformer (TC4-1W, 3-800MHz) is used. The analog outputs are designed to drive a
50
Ω load. The maximum output voltage range is 1.0V
P-P
.
4.5 External clock input
The external clock input can be configured in two ways (see also Figure 4):
