PCB Layout Guidelines
Care should be taken in the PCB layout in order to
avoid any noise generated from MCU coupling into
the RF stage. For example:
The power supply traces used for digital and analog
circuit blocks should be separated.
The location of decoupling capacitors should be as
close as possible to device’s supply input pins (VDD /
VSS or VCC / GND).
The VDD to VSS ground loop area should be reduced
to minimize the magnetic coupling effect.
The PCB trace loop formed by any input/output (I/O)
signal pin should be kept to a minimum.
The RF receiver uses a loop antenna formed by using a
PCB trace line.
Some details on ADNK-5033-FS27
The ADNK-5033-FS27 reference design mouse unit
allows users to evaluate the performance of the Optical
Tracking Engine (sensor, lens, LED assembly clip, LED)
over a USB connection, using a Freescale USB
Microcontroller. This kit also enables users to
understand the recommended mechanical assembly.

System Requirements
PCs using Windows 95/ Windows 98/ Windows
NT/ Windows 2000 with standard 3-button USB
mouse driver loaded.
Functionality
3-buttons, scroll wheel combi-mouse.
USB Operating Mode
Hot pluggable with USB port. The PC does not need to
be powered off when plugging or unplugging the
evaluation mouse.
To Disassemble the ADNK-5033-FS27 Unit
The ADNK-5033-FS27 comprises of the plastic mouse
casing, printed circuit board (PCB), lens, buttons, and
USB cable (See Figure 5). Unscrewing the one screw
located at the base of the unit can open the ADNK-
5033-FS27 unit. Lifting and pulling the PCB out of the
base plate can further disassemble the mouse unit.
Caution: The lens is not permanently attached to the sensor and
will drop out of the assembly.
