36 Chapter 5: Matrox Orion hardware reference
A/D converters Matrox Orion uses three independent 10-bit analog/digital
converters, one for each R, G, and B channel. Although 10-bit
converters are used, the converters only output the 8
most-significant bits of data. The converter can operate at the
maximum pixel clock frequency of the decoder (14.75 MHz)
1
.
In addition, the converter’s black and white reference levels can
be adjusted individually. The black and white reference levels
can be adjusted between 0.6 V to 1.6 V and 1.6 V to 2.6 V
respectively, in increments of 10.23 mV (98 distinct
adjustments). Use the MIL-Lite MdigReference() command to
set the black and white reference levels.
