LG1626DXC Modulator Driver
Electrical Characteristics
(continued)
5-6554(F).b
*A 2.5 k
resistor will set the eye crossing at 50%. A 5 k
potentiometer will allow the eye crossing to be varied.
Notes:
All bypass caps should be mounted close to the package.
I
SS3
can be measured and used to control V
MOD
.
I
SS2
can be measured and used to control V
OUT-DC
.
For optimal performance, the proximity of the two components should be minimized and the package bottom must be soldered to the circuit
board (GND).
For proper impedance matching, high-speed transmission lines should be 50
controlled impedance lines.
