The TBC/Frame Synchronizer performs time base correction and synchronization
on its input signal (either analog or digital) to conform its timing to the house
reference provided on the external reference input (Ref In). This synchronizing
function will automatically align the timing of the converter output so that each
new video frame begins at exactly the same time as it does on the reference
input. Furthermore, since the original input to the converter may be non-syn-
chronous to the reference, the input video may be running slightly fast or slow
with respect to the reference. The synchronizer corrects for this by buffering the
signal through a memory FIFO which can hold up to one frame of video.
The output of the TBC/Frame Synchronizer is serialized as a 270 Mb/s bitstream
and feeds the electrical BNC connector.
BrightEye 3 is powered by a 12 volt DC universal power supply. This power
supply can accept an input voltage between 90 and 230 volts, at 50 or 60 Hertz. It
uses a standard IEC line cord and can be used anywhere in the world. It is
normal for the converter to be quite warm to the touch when operating.
