2. Detailed Description
2.1 Operation
The UHD converter reference design has 5 BNC ports: 1 dedicated input (J1), 1 dedicated
output (J5) and three bidirectional ports (J2-J4). The bidirectional ports make the design
very flexible, minimizing the physical size of the design and reducing the BNC port
count.
The RDK-12GCONV board is powered from a 12V wall adapter, included in the kit.
This board is designed to aid users in the evaluation of Semtech 12G devices without
needing to connect to an external computer. Advanced features can be accessed
through the GUI by connecting the board via USB interface.
The UHD configuration modes can be selected using the rotary switch mounted on the
printed circuit board, or by software GUI via the USB port (J8). The selected mode can be
observed through the illuminated LEDs.
Table 2-1
illustrates the supported modes and associated LED indicators with each
mode selected.
Note:
While turning the
Mode
selector, the output mode will be displayed as a Binary
Coded Decimal (BCD) value via the I/O Rate LEDs (see Mode Select column of
Table 2-1
).
When the
Mode
selector is not in use, the mode/rate LEDs display the selected I/O rates
(see LEDs column of
Table 2-1
).
