they are mounted onto defined
features on the base plate.
The ADNS-6030 laser mouse
sensor is designed for
mounting on a through hole
PCB, looking down. There is
an aperture stop and features
on the package that align to
the lens.
The ADNV-6330 VCSEL is
recommended for illumination
provides a laser diode with a
single longitudinal and a single
transverse mode. It is
particularly suited as lower
power consumption and highly
coherent replacement of LEDs.
It also provides wider
operation range while still
remaining within single-mode,
reliable operating conditions.

The ADNS-6120 or ADNS6130-001 Laser Mouse Lens is
designed for use with ADNS6030 sensor and the
illumination subsystem
provided by the assembly clip
and the VCSEL. Together with
the VCSEL, the lens provides
the directed illumination and
optical imaging necessary for
proper operation of the Laser
Mouse Sensor. ADNS-6120 and
ADNS-6130-001 are precision
molded optical components
and should be handled with
care to avoid scratching of the
optical surfaces. ADNS-6120
also has a large round flange
to provide a long creepage
path for any ESD events that
occur at the opening of the
base plate.
The ADNS-6230-001 VCSEL
Assembly Clip is designed to
provide mechanical coupling of
the ADNV-6330 VCSEL to the
ADNS-6120 or ADNS-6130-001
lens. This coupling is essential
to achieve the proper
illumination alignment required
for the sensor to operate on a
wide variety of surfaces.
Agilent Technologies provides
an IGES file drawing
describing the base plate
molding features for lens and
PCB alignment.

Assembly Recommendation
1. Insert the sensor and all
other electrical components
into the application PCB
(main PCB board and
VCSEL PCB board).
2. Wave-solder the entire
assembly in a no-wash
solder process utilizing a
solder fixture. The solder
fixture is needed to protect
the sensor during the solder
process. It also sets the
correct sensor-to -PCB
distance, as the lead
shoulders do not normally
rest on the PCB surface.
The fixture should be
designed to expose the
sensor leads to solder while
shielding the optical
4
aperture from direct solder
contact.
6. Remove the protective cap
from the VCSEL.
3. Place the lens onto the base
plate.
7. Insert the VCSEL assembly
into the lens.
4. Remove the protective
kapton tape from the optical
aperture of the sensor. Care
must be taken to keep
contaminants from entering
the aperture.
8. Slide the clip in place until
it latches. This locks the
VCSEL and lens together.
5. Insert the PCB assembly
over the lens onto the base
plate. The sensor aperture
ring should self-align to the
lens. The optical position
reference for the PCB is set
by the base plate and lens.
Note that the PCB motion
due to button presses must
be minimized to maintain
optical alignment.
9. Tune the laser output power
from the VCSEL to meet the
Eye Safe Class I Standard
as detailed in the LASER
Power Adjustment
Procedure.
10. Install the mouse top case.
There must be a feature in
the top case (or other area)
to press down onto the
sensor to ensure the sensor
and lens are interlocked to
the correct vertical height.

LASER Drive Mode
LASER Power Adjustment Procedure
The laser is driven in pulsed
mode during normal operation.
A calibration mode is provided
which drives the laser in
continuous (CW) operation.
1. The ambient temperature
should be 25C +/- 5C.
Eye Safety
The ADNS-6030 and the
associated components in the
schematic of Figure 5 are
intended to comply with Class
1 Eye Safety Requirements of
IEC 60825-1. Agilent
Technologies 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 ADNS6030 generates the drive
current for the laser diode
(ADNV-6330).
In order to stay below the
Class 1 power requirements,
LASER_CTRL0 (register 0x1a),
LASER_CTRL1 (register 0x1f),
LSRPWR_CFG0 (register 0x1c)
and LSRPWR_CFG1 (register
0x1d) must be programmed to
appropriate values. The system
comprised of the ADNS-6030
and ADNV-6330, is designed to
maintain the output beam
power within Class 1
requirements over components
manufacturing tolerances and
the recommended temperature
range when adjusted per the
procedure below and
implemented as shown in the
recommended application
circuit of Figure 5. For more
information, please refer to
Agilent ADNB-6031 and
ADNB-6032 Laser Mouse
Sensor Eye Safety Application
Note AN 5230.

2. Set VDD to its permanent
value.
3. Set the Range bit (bit 7 of
register 0x1a) to 0.
4. Set the Range_C complement
bit (bit 7 of register 0x1f) to
1.
5. Set the Match_bit (bit 5 of
register 0x1a) to the correct
value for the bin designation
of the laser being used.
6. Set the Match_C_bit (bit 5
of register 0x1f) to the
complement of the
Match_bit.
7. Enable the Calibration mode
by writing to bits [3,2,1] of
register 0x1A so the laser
will be driven with 100%
duty cycle.
8. Write the Calibration mode
complement bits to register
0x1f.
9. Set the laser current to the
minimum value by writing
0x00 to register 0x1c, and
the complementary value
0xFF to register 0x1d.
10. Program registers 0x1c and
0x1d with increasing values
to achieve an output power
as close to 506uW as
possible without exceeding
it. If this power is obtained,
the calibration is complete,
skip to step 14.
11. If it was not possible to
achieve the power target, set
the laser current to the
minimum value by writing
0x00 to register 0x1c, and
the complementary value
0xff to register 0x1d.
12. Set the Range and Range_C
bits in registers 0x1a and
0x1f, respectively, to choose
to the higher laser current
range.
13. Program registers 0x1c and
0x1d with increasing values
to achieve an output power
as close to 506uW as
possible without exceeding
it.
14. Save the value of registers
0x1a, 0x1c, 0x1d, and 0x1f
in non-volatile memory in
the mouse. These registers
must be restored to these
values every time the
ADNS-6030 is reset.
15. Reset the mouse, reload
the register values from
non-volatile memory, enable
Calibration mode, and
measure the laser power to
verify that the calibration is
correct.
Good engineering practices
such as regular power meter
calibration, random quality
assurance retest of calibrated
mice, etc. should be used to
guarantee performance,
reliability and safety for the
product design.
LASER Output Power
Disabling the LASER
The laser beam output power
as measured at the navigation
surface plane is specified
below. The following conditions
apply:
LASER_NEN is connected to
the gate of a P-channel
MOSFET transistor which when
ON connects VDD to the
LASER. In normal operation,
LASER_NEN is low. In the
case of a fault condition
(ground or VDD at XY_LASER),
LASER_NEN goes high to turn
the transistor off and
disconnect VDD from the
LASER.
1. The system is adjusted
according to the above
procedure.
2. The system is operated
within the recommended
operating temperature range.
3. The VDD value is no greater
than 300mV above its value
at the time of adjustment.
4. No allowance for optical
power meter accuracy is
assumed.
Single Fault Detection
ADNS-6030 is able to detect a
short circuit or fault condition
at the XY_LASER pin, which
could lead to excessive laser
power output. A path to
ground on this pin will trigger
the fault detection circuit,
which will turn off the laser
drive current source and set
the LASER_NEN output high.
When used in combination
with external components as
shown in the block diagram
below, the system will prevent
excess laser power for a
resistive path to ground at
XY_LASER by shutting off the
laser. In addition to the
ground path fault detection
described above, the fault
detection circuit is
continuously checked for
proper operation by internally
generating a path to ground
with the laser turned off via
LASER_NEN. If the XY_LASER
pin is shorted to VDD, this test
will fail and will be reported
as a fault.

Laser Mouse Sensor
Features
• Low power architecture
• New LaserStream technology
Theory of Operation
The ADNS-6030 is based on
LaserStream Technology,
which measures changes in
position by optically acquiring
sequential surface images
(frames) and mathematically
determining the direction and
magnitude of movement.
The ADNS-6030 contains an
Image Acquisition System
(IAS), a Digital Signal
Processor (DSP), and a four
wire serial port. The IAS
acquires microscopic surface
images via the lens and
illumination system. These
images are processed by the
DSP to determine the direction
and distance of motion. The
DSP calculates the ∆x and ∆y
relative displacement values.
An external microcontroller
reads the ∆x and ∆y
information from the sensor
serial port. The
microcontroller then translates
the data into PS2, USB, or RF
signals before sending them to
the host PC or game console.

Power management modes
Synchronous Serial Port
Chip Select Operation
The ADNS-6030 has three
power-saving modes. Each
mode has a different motion
detection period, affecting
response time to mouse motion
(Response Time). The sensor
automatically changes to the
appropriate mode, depending
on the time since the last
reported motion (Downshift
Time). The parameters of each
mode are shown in the
following table.
The synchronous serial port is
used to set and read
parameters in the ADNS-6030,
and to read out the motion
information.
The serial port is activated
after NCS goes low. If NCS is
raised during a transaction,
the entire transaction is
aborted and the serial port
will be reset. This is true for
all transactions. After a
transaction is aborted, the
normal address-to-data or
transaction-to-transaction
delay is still required before
beginning the next transaction.
To improve communication
reliability, all serial
transactions should be framed
by NCS. In other words, the
port should not remain
enabled during periods of nonuse because ESD and EFT/B
events could be interpreted as
serial communication and put
the chip into an unknown
state. In addition, NCS must
be raised after each burstmode transaction is complete
to terminate burst-mode. The
port is not available for
further use until burst-mode is
terminated.

Motion Pin Timing
The motion pin is a levelsensitive output that signals the
micro-controller when motion
has occurred. The motion pin
is lowered whenever the
motion bit is set; in other
words, whenever there is data
in the Delta_X or Delta_Y
registers. Clearing the motion
bit (by reading Delta_X and
Delta_Y, or writing to the
Motion register) will put the
motion pin high.
LASER Mode
For power savings, the VCSEL
will not be continuously on.
ADNS-6030 will flash the
VCSEL only when needed.
16
The port is a four-wire port.
The host micro-controller
always initiates communication;
the ADNS-6030 never initiates
data transfers. SCLK, MOSI,
and NCS may be driven
directly by a micro-controller.
The port pins may be shared
with other SPI slave devices.
When the NCS pin is high, the
inputs are ignored and the
output is tri-stated.
The lines that comprise the
SPI port:
SCLK: Clock input. It is
always generated by the
master (the micro-controller).
MOSI: Input data. (Master
Out/Slave In)
MISO: Output data. (Master
In/Slave Out)
NCS: Chip select input
(active low). NCS needs to be
low to activate the serial port;
otherwise, MISO will be high Z,
and MOSI & SCLK will be
ignored. NCS can also be
used to reset the serial port in
case of an error.
Write Operation
Read Operation
Write operation, defined as
data going from the microcontroller to the ADNS-6030,
is always initiated by the
micro-controller and consists
of two bytes. The first byte
contains the address (seven
bits) and has a “1” as its MSB
to indicate data direction. The
second byte contains the data.
The ADNS-6030 reads MOSI on
rising edges of SCLK.
A read operation, defined as
data going from the ADNS6030 to the micro-controller, is
always initiated by the microcontroller and consists of two
bytes. The first byte contains
the address, is sent by the
micro-controller over MOSI,
and has a “0” as its MSB to
indicate data direction. The
second byte contains the data
and is driven by the ADNS6030 over MISO. The sensor
outputs MISO bits on falling
edges of SCLK and samples
MOSI bits on every rising edge
of SCLK.

Note: The 0.5/fSCLK minimums
high state of SCLK is also the
minimum MISO data hold time
of the ADNS-6030. Since the
falling edge of SCLK is actually
the start of the next read or
write command, the ADNS6030 will hold the state of
data on MISO until the falling
edge of SCLK.

Required timing between Read and
Write Commands
There are minimum timing
requirements between read
and write commands on the
serial port.
If the rising edge of the SCLK
for the last data bit of the
second write command occurs
before the required delay
(tSWW), then the first write
command may not complete
correctly.
If the rising edge of SCLK for
the last address bit of the read
command occurs before the
required delay (tSWR), the
write command may not
complete correctly.
During a read operation SCLK
should be delayed at least
tSRAD after the last address
data bit to ensure that the
ADNS-6030 has time to
prepare the requested data.
The falling edge of SCLK for
the first address bit of either
the read or write command
must be at least tSRR or tSRW
after the last SCLK rising edge
of the last data bit of the
previous read operation.
Burst Mode Operation
Burst mode is a special serial
port operation mode that may
be used to reduce the serial
transaction time for a motion
read. The speed improvement
is achieved by continuous data
clocking to or from multiple
registers without the need to
specify the register address,
and by not requiring the
normal delay period between
data bytes.
Burst mode is activated by
reading the Motion_Burst
register. The ADNS-6030 will
respond with the contents of
the Motion, Delta_X, Delta_Y,
SQUAL, Shutter_Upper,
Shutter_Lower and
Maximum_Pixel registers in
that order. The burst
transaction can be terminated
anywhere in the sequence after
the Delta_X value by bringing
the NCS pin high. After
sending the register address,
the micro-controller must wait
tSRAD and then begin reading
data. All data bits can be
read with no delay between
bytes by driving SCLK at the
normal rate. The data are
latched into the output buffer
after the last address bit is
received. After the burst
transmission is complete, the
micro-controller must raise the
NCS line for at least tBEXIT to
terminate burst mode. The
serial port is not available for
use until it is reset with NCS,
even for a second burst
transmission.

Notes on Power-up
Notes on Shutdown and Forced Rest
The ADNS-6030 does not
perform an internal power up
self-reset; the
POWER_UP_RESET register
must be written every time
power is applied. The
appropriate sequence is as
follows:
The ADNS-6030 can be set in
Rest mode through the
Configuration_Bits register
(0x11). This is to allow for
further power savings in
applications where the sensor
does not need to operate all
the time.
1. Apply power
The ADNS-6030 can be set in
Shutdown mode by writing
0xe7 to register 0x3b. The SPI
port should not be accessed
when Shutdown mode is
asserted, except the power-up
command (writing 0x5a to
register 0x3a). (Other ICs on
the same SPI bus can be
accessed, as long as the
sensor’s NCS pin is not
asserted.) The table below
shows the state of various pins
during shutdown. To deassert
Shutdown mode:
2. Drive NCS high, then low to
reset the SPI port
3. Write 0x5a to register 0x3a
4. Wait for tWAKEUP
5. Write 0xFE to register 0x28
6. Read from registers 0x02,
0x03 and 0x04 (or read
these same 3 bytes from
burst motion register 0x42)
one time regardless of the
motion pin state.
During power-up there will be
a period of time after the
power supply is high but
before any clocks are available.
The table below shows the
state of the various pins
during power-up and reset.
19
1. Write 0x5a to register 0x3a
2. Wait for tWAKEUP
3. Write 0xFE to register 0x28
4. Any register settings must
then be reloaded.
*1 NCS pin must be held to 1
(high) if SPI bus is shared
with other devices. It is
recommended to hold to 1
(high) during Power Down
unless powering up the
Sensor. It must be held to 0
(low) if the sensor is to be
re-powered up from
shutdown (writing 0x5a to
register 0x3a).
*2 Depend on last state
*3 SCLK is ignore if NCS is 1
(high). It is functional if
NCS is 0 (low).
*4 MOSI is ignore if NCS is 1
(high). If NCS is 0 (low),
any command present on
the MOSI pin will be
ignored except power-up
command (writing 0x5a to
register 0x3a).
Note: There are long wakeup
times from shutdown and
forced Rest. These features
should not be used for power
management during normal
mouse motion.

USAGE : Register 0x02 allows the user to determine if motion has occurred since the last time it
was read. If the MOT bit is set, then the user should read registers 0x03 and 0x04 to get the
accumulated motion. Read this register before reading the Delta_X and Delta_Y registers.
Writing anything to this register clears the MOT and OVF bits, Delta_X and Delta_Y registers. The
written data byte is not saved.
Internal buffers can accumulate more than eight bits of motion for X or Y. If either one of the
internal buffers overflows, then absolute path data is lost and the OVF bit is set. To clear
theoverflow, write anything to this register.
Check the OVR bit if more than 4" of motion is accumulated without reading it. If bit set, discard
the motion as erroneous. Write anything to this register to clear the overflow condition.
The PIXRDY bit will be set whenever a valid pixel data byte is available in the Pixel_Dump
register. Check that this bit is set before reading from Pixel_Dump. To ensure that the Pixel_Grab
pointer has beenreset to pixel 0,0 on the initial write to Pixel_Grab, check to see if PIXFIRST is
set to high.

USAGE : SQUAL (Surface Quality) is a measure of the number of valid features visible by the
sensor in the current frame.
The maximum SQUAL register value is 127. Since small changes in the current frame can result
in
changes in SQUAL, variations in SQUAL when looking at a surface are expected. The
graph below shows 800 sequentially acquired SQUAL values, while a sensor was moved slowly
over white paper. SQUAL is nearly equal to zero, if there is no surface below the sensor.
SQUAL is typically maximized when the navigation surface is at the optimum distance from the
imaging lens (the nominal Z-height).

Data Type
: High 8 bits of an unsigned 17-bit integer.
USAGE : This register is used to find the average pixel value. It reports the upper eight bits of
a 17-bit counter, which sums all pixels in the current frame. It may be described as the full sum
divided by 512. To find the average pixel value, use the following formula:
Average Pixel = Register Value * 512/484 = Register Value * 1.058
The maximum register value is 241. The minimum is 0. The pixel sum value can change on every
frame.

Data Type
: Eight-bit word.
USAGE : For test purposes, the sensor will read out the contents of the pixel array, one pixel per
frame. To start a pixel grab, write anything to this register to reset the pointer to pixel 0,0.
Then read the PIXRDY bit in the Motion register. When the PIXRDY bit is set, there is valid data
in this register to read out. After the data in this register is read, the pointer will automatically
increment to the next pixel. Reading may continue indefinitely; once a complete frame’s worth of
pixels has been read, PIXFIRST will be set to high to indicate the start of the first pixel and the
address pointer will start at the beginning location again.

Agilent ADNV-6330
Single-Mode Vertical-Cavity Surface Emitting Laser
(VCSEL)
Description
This advanced class of VCSELs
was engineered by Agilent to
provide a laser diode with a
single longitudinal and a single
transverse mode. In contrast to
most oxide-based single-mode
VCSELs, this class of Agilent
VCSELs remains within single
mode operation over a wide
range of output power. The
ADNV-6330 has significantly
lower power consumption than
a LED. It is an excellent
choice for optical navigation
applications.

section in the ADNS-6030
laser sensor datasheet.
3. The inherent design of this
component causes it to be
sensitive to electrostatic
discharge. The ESD
threshold is listed above. To
prevent ESD-induced
damage, take adequate ESD
precautions when handling
this product.
Notes:
1. Duration = 100ms, 10% duty cycle
2. I = 10µA
3. See IR reflow profile (Figure 36)
Comments:
Danger:
VCSELs are sorted into bins as
specified in the power
adjustment procedure section
in the ADNS-6030 laser sensor
datasheet. Appropriate binning
resistor and register data
values are used in the
application circuit to achieve
the target output power.
When driven with current or
temperature range greater than
specified in the power
adjustment procedure section,
eye safety limits may be
exceeded. The VCSEL should
then be treated as a Class IIIb
laser and as a potential eye
hazard.
