Introduction
Figure 1 shows a detailed block diagram of the E7765.
Each of the four drivers has independent signal control
and voltage inputs. In addition, each driver has
independent power-down ability as well as adjustability
for output rising and falling edge speeds.
Refer to Table 1 for a truth table depicting the different
modes of operation of an individual channel. Table 2
expands on the independent operations with a description
of the differential drive mode operation. Differential pair[0]
consists of drive channels 0 and 1 and are controlled by
SEL_DHI[0]. Differential pair[1] consists of drive channels
2 and 3 and are controlled by SEL_DHI[1].
Channels 1, 2 and 3 similar. SEL_DHI[0] and [1] at logical low.
