ICS1531 Daughterboard - Preliminary
Figure 1-2
shows the location of all components used to configure the ICS1531 DAC Daughterboard.
Figure 1-2.
DAC Daughterboard for ICS1531 Demo Board
Table 1-2
lists and describes relevant components on the ICS1531 DAC Daughterboard, a schematic for
which is in
Chapter 3, “Schematics”
. For the DAC daughterboard, the input must be digital
(1 pixel/clock) and the output is analog (1 pixel/clock).
