DMD2050 Universal Satellite Modem Theory of Operation
The DMD2050 Baseband Processing Printed Circuit Card provides a flexible architecture that
allows many different modes of terrestrial and satellite framing, various FEC options, digital voice
processing, and several different modulation/demodulation formats. Also included on the
Baseband Printed Circuit Card are three synchronous interfaces, an EIA-530 Interface supporting
MIL-188-114A and RS-422. All three interfaces are provided on the same DB-25 Connector, and
are selectable from the front panel.
A block diagram of the Baseband Processing Card is shown in Figure 3-3.
