Revision 1.7.1

Added documentation
There are no changes made to the PCB comparing to version 1.7.

PCB revision 1.7

Changes:

• Add capacitance with series resistor to LD- to create a low impedance node for current modulation
• Add 1k series resistor at current mod. input buffer for defined roll-off at ~100MHz

Minor revisions:

• Update to KiCad 6
• Add 3D model for DVI connector

PCB revision 1.6

Remove impedance matching (inductance and 49.9 Ohm) at Ld-

Minor revisions:

• Move R7 to the front
• Use SMD solder pads for piezo connection
• R3=100k to reduce relay circuit idle current
• Additional revison label on the front side

Revision 1.5

-Fix laser diode polarity at DVI connector
-Replace XGL3530 by XGL5050
-Options for no inductance at LD- and ground referenced design

Revision 1.4

-Replace Bias-T with Howland current source. Add dual supply with +/- 5V LDOs.
-Replace 5.6Ohm resistors with XGL3530 coils and 49.9Ohm resistors
-Use solder pad for LD- connection

PCB revision 1.3

Connector: Conn Link CDVI-F29VDG1-P1 with standard mounting holes
replaces the obsolete Molex connector (with non-standard mounting holes).

Relay pins changed from 8/14 to 16/14 since DVI cables do not connect pin 8.

Add 1k resistors to diode voltage sense conncetion
