Setting Analog Output Option Jumpers

The Analog Output Option leaves the factory set to produce the following
analog output signal parameters:

RGB

0.700V peak signal level

No Setup

RP125 narrow blanking

To change any of these parameters, follow the steps given below:

Blanking Width and Video Setup

1. On the 064912 Analog Output Support board (the larger mezzanine

board), set jumper J6 for the blanking width that you want on the
analog output: RS-170 or RP-125.

When the jumper is set to RS-170 (wide blanking), blanking edges
follow RS-170 specifications for 60 Hz systems or follow the CCIR 470-2
recommendation for 50 Hz systems. When set to RP-125, blanking is
active from end of active video (EAV) to start of active video (SAV),
inclusive, as described in SMPTE RP-125.

2. On the 064912 Analog Output Support board (the larger mezzanine

board), set jumper J7 for the appropriate setup level on the analog
output: Setup (54 mV) or No Setup. See Table 2-1 for the setup
requirements of various video formats.
