LG1625AXF Laser Driver

Electrical Characteristics

TA = 25 °C, VSS1 = VSS2 = VSS3 = –5.2 V, VTH = –1.3 V, VMOD = –3.4 V, RL = 25 Ω, data input = 600 mVp-p.

Minimum and Maximum values are testing requirements. Typical values are characteristics of the device and are

the result of engineering evaluations. Typical values are for information purposes only and are not part of the test-

ing requirements. Stresses in excess of the absolute maximum ratings can cause permanent damage to the

device.
