... E7765 has bias and other inputs that provide a means to adjust performance versus power consumption. The E7765 operates at data rates up to 1.3 GHz/2.6 Gbps. The power supplies to the E7765 are specified over a wide range to accommodate between –2V, +7V and –0.5V, +4.2V output voltage ranges. The E7765 driver is capable of generating 8V swings over a – ...

... Introduction Introduction Introduction Introduction 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 ...
