Base Plate Feature – IGES File
The IGES fi le on the CD-ROM provides recommended
base plate molding features to ensure optical alignment.
This includes PCB assembly diagrams like solder fi xture in
assembly and exploded view, as well as solder plate. See
Appendix D for details.
Reference Design Documentation – Gerber File
The Gerber File presents detailed schematics used in
ADNK-6003-SP01 in PCB layout form. See Appendix C for
more details.
Overall circuit
A schematic of the overall circuit is shown in Appendix A
of this document. Appendix B lists the bill of materials.
LASER Power Adjustment Procedure
1. The ambient temperature should be 25 ° C ± 5 ° C.
2. Set VDD3 to its permanent value.
3. Ensure that the laser drive is at 100% duty cycle by
setting bit 6 of register 0x0A to 0.
4. Program the LP_CFG0 and LP_CFG1 registers to
achieve an output power as close to 506uW as
possible without exceeding it.
Good engineering practices should be used to guarantee
performance, reliability and safety for the product design.
LASER Output Power
The laser beam output power as measured at the naviga-
tion surface plane is specifi ed below. The following condi-
tions apply:
1. The system is adjusted according to the above
procedure.
2. The system is operated within the recommended
operating temperature range.
3. The VDD3 value is no greater than 50mV above its
value at the time of adjustment.
4. No allowance for optical power meter accuracy is
assumed.
