Figure A
below shows a block diagram of the features and the functions of the
EB-GS3471-00.
The board includes power supplies, USB control interface, two 3G-SDI inputs, one
GS3140 equalizer, a 3G-SDI loop-through output, a GS2988 multi-rate cable driver, a
GS3471 Receiver, a parallel video output connector, an audio output with four RCA for
AES audio, a 27MHz crystal, DIP switches, and a few status indication LEDs.
The GS3471 will automatically detect the input signal (J6 and J7) as SD-SDI, HD-SDI, or
3G-SDI. The deserialized video is available on the parallel output connector (J1). The
extracted audio is available as serial audio or AES on audio headers (J4 and J12). A serial
digital loop-through output (J10) is also available.
The EB-GS3471-00 also provides a JTAG interface used for boundary scan and a USB
interface to control the GS3471 and the GS3140 through the GSPI ports on the devices.
