Figure 25: DX-2200-TI
– HD-SDI Text & Graphics Inserter Board
The
DX-2200-TI
– HD-SDI Text & Graphic Inserter Board
is utilizes the following hardware devices:
•
Cyclone EP3C120F780C7N FPGA
•
SDRAM Memory: 256 MB (64-bit interface), 4 x Micro MT47H32M16BN-3, 32Mx16b DDR2
•
Gennum GS2962 3G/HD/SD-SDI Serializer (Transmitter) with Cable Driver
•
Gennum GS2962 3G/HD/SD-SDI Deserializer (Receiver) with Equalizer
•
Gennum GS4911B HD/SD/Graphics Clock and Timing Generator
•
The following sections describe the hardware used in each of the two product configurations.
A.1 SDI Video Interfaces
The
DX-2200-TI
supports one SD/HD-SDI input and one SD/HD-SDI output port. These interfaces support
SMTP 292M video formats. The SDI output is reclocked from a Gennum Timing Generator which runs
asynchronously to the video inputs.
A.2 RS-232 Serial Control Port
The RS-232 Serial Control Port is used to control the text overlay. It is a DB9 female connector. The Control
Port transmit and receive data is on the standard pin numbers 2 & 3, and the port is set at 115,200 baud
operation (8N1). There is no hardware flow control for the Control Port.
For units with board revision D and above, the connector is customized with a second port on pins 7 & 8.
The second port is used for the GPS data receiver function and other customized product variations. The
baud rate of the second port depends on the application.
