Rev. 3 C–9
C.1.4 Connect to SDM-2020 Satellite Modulator with EIA-422 (DVB) TX
Interface (100 Mbit/s Parallel Data)
Note: The section defines the requirements of the EIA-422 (DVB) TX data interface for
video and high-speed data applications used with the SDM-2020 Satellite Modulator.
C.1.4.1 Description
The SMS-301 data interface is a plug-in module that interfaces with the SDM-2020
Satellite Modulator. The maximum data rate is 100 Mbit/s for parallel data.
The SDM-2020 Modulator configured with the EIA-422 data interface is identified as
follows:
•
Parallel Connector (J3) is used for DVB EIA-422 either parallel or serial data.
•
Serial connector (J3) is for (EIA-530) serial differential data operation.
Note: SDM-2020 Modulator with ASI/EIA-422 data interface can be configured using
the same instructions as the EIA-422 configuration.
