TYPICAL APPLICATIONS
3-Input Video MUX Cable Driver
The application on the rst page of this data sheet shows
a low cost, 3-input video MUX cable driver. The scope
photo below (Figure 4) displays the cable output of a
30MHz square wave driving 150Ω. In this circuit the ac-
tive amplier is loaded by the sum of RF and RG of each
disabled amplier. Resistor values have been chosen to
keep the total back termination at 75Ω while maintaining
a gain of 1 at the 75Ω load. The switching time between
any two channels is approximately 32ns when both enable
pins are driven (Figure 5).
When building the board, care was taken to minimize trace
lengths at the inverting inputs. The ground plane was also
pulled a few millimeters away from RF and RG on both
sides of the board to minimize stray capacitance.
Using the LT6559 to Drive LCD Displays
Driving a variety of XGA and UXGA LCD displays can be
a difcult problem because they are usually a capacitive
load of over 300pF, and require fast settling.
The LT6559 is particularly well suited for driving these LCD
displays because it can drive large capacitive loads with a
small series resistor at the output, minimizing settling time.
As seen in Figure 6, at a gain of +3 with a 16.9Ω output
series resistor and a 330pF load, the LT6559 is capable
of settling to 0.1% in 30ns for a 6V step.
