2.13 Analog Output Specifications
The DAC outputs are controlled by three current sources (only two for IOR and IOB) as shown in
Figure 2–13. The default condition is to have 0-IRE difference between blank and black levels, which is
shown in Figure 2–15. If a 7.5-IRE pedestal is desired, it can be selected by setting bit 4 of the general-control
register. This video output is shown in Figure 2–14.

Figure 2–13. Equivalent Circuit of the Current Output (IOG)
A resistor (R
SET
) is needed between the FS ADJUST terminal and GND to control the magnitude of the
full-scale video signal. The IRE relationships in Figures 2–14 and 2–15 are maintained regardless of the
full-scale output current.
The relationship between R
