following Avago Technologies recommendations.
•
Passes EN61000-4-4/IEC801-4 EFT tests when assembled
into a mouse with shielded cable and following Avago
Technologies recommendations.

mouse according to usage instructions above.
Eye Safety
The ADNS-6010 and the associated components in the
schematic of Figure A1 are intended to comply with Class
1 Eye Safety Requirements of IEC 60825-1. Avago Tech-
nologies suggests that manufacturers perform testing to
verify eye safety on each mouse. It is also recommended
to review possible single fault mechanisms beyond those
described below in the section “Single Fault Detection”.
Under normal conditions, the ADNS-6010 generates the
drive current for the laser diode (ADNV-6340). In order to
stay below the Class 1 power requirements, resistor Rbin
must be set at least as high as the value in the bin table,
based on the bin number of the laser diode and LP_CFG0
and LP_CFG1 must be programmed to appropriate values.
Avago Technologies recommends using the exact Rbin
value specifi ed in the bin table to ensure suffi
cient laser
power for navigation. The system comprised of the ADNS-
6010 and ADNV-6340 is designed to maintain the output
beam power within Class 1 requirements over component
manufacturing tolerances and the recommended tem-
perature range when adjusted per the procedure below
and when implemented as shown in the recommended
application circuit of Figure A1. For more information,
please refer to Eye Safety Application Note 5088.
LASER Power Adjustment Procedure
1. The ambient temperature should be 25C +/- 5C.
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.
