4 Video Signal Requirements

4.1Video Input Lines

The video signal connector that connects to the customer’s equipment is a female 15-pin connector in a high density 9-pin D-Shell housing. Pin number assignments are defined in Table 4, and physical layout as seen by the interface cable from user logic is shown in Error! Reference source not found. The "NC" positions of this connector are not used for any purpose.

4.2.1Video Parameters

As seen by the video source, input resistance is 75-ohm, ±10%; input capacitance at (150 MHZ) <10-pF. The video input signal must have a range of 0-mv to 714-mv (maximum) where 0-mv is minimum luminance. Rise and fall times for the input signal (10% - 90%) will be 5-ns (Figure 4). When terminated with a 75-ohm termination, the dark state (black level) is
