LG1626DXC Modulator Driver
Electrical Characteristics
TA = 25 °C, VSS1 = VSS2 = VSS3 = –5.2 V, VTH = – 1.3 V, VMOD = – 3.8 V, RL = 50 Ω.
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.

1. Maximum output modulation at maximum VMOD (RL = 50 Ω).
2. Minimum output modulation when MOD_E is floating and VMOD = VSS3.
3. Excludes IPRE and average IMOD:
Power suppy current ISS2 (relating to prebias) is dependent on VPRE.
Power suppy current ISS3 (relating to modulation) is dependent on VMOD.
4. Both MK and MK are open drains, the typical value is obtained by driving a 1kΩ load.
5. Maximum modulator dc offset voltage (RL = 50 Ω) at maximum VDC-ADJ.
6. Minimum modulator dc offset voltage (RL = 50 Ω) at VDC-ADJ = VSS2.
Note: All parameters measured at 25 °C ambient.
