3-14 Connector Pinouts and Cable Information
brightness), VOUT, and COUT (chrominance or color) are the outputs of
the SM731 VGA to NTSC/PAL encoder.
Loopback Mode
Note that as a test feature, a control bit can make the VOUT loopback to
VIN1. The only time the loopback should be enabled is when VIN1 is not
otherwise connected.
RGBHV Input
The MDSM15 connector can be used to connect to the high-speed (HS)
digitizer, which acquires RGBHV or RGB + SOG, up to 1280 x 1024 at
120 MHz. The table above shows the
Pinout MDSMA
pin definitions
share pins between the NTSC/PAL digitizer and the high-speed digitizer.
The connections are wired in parallel except for that the 75-ohm
terminations on VIN3 and CIN are removed in HS mode.
3.6.2 Pinout MDSMB – DVI Input
The MDSM15 connector can also be used to connect to the DVI inputs of
the high-speed AD9882 digitizer at up to 1024 x 768. The table above
shows the
Pinout MDSMB
pin definitions. Using this mode is definitely a
second choice to using the DVI-I connector’s (usually) DVI output
function for digitizing.
