6.2 PCB Layout Guideline
The following guidelines apply to component placement and routing on the PCB. That will get an optimum
EMC solution and tracking performance.
6.2.1 Key Components Placement Rules
1. Place resonator Y1 near SENSOR’s pin2 and pin 3.
2. Place bulk capacitor C1 and bypass C2 near the USB CABLE.
3. Place C3 and C4 near SENSOR’s pin9 and pin10.
4. The C5/C6 and R3/R4 should be placed as close to the USB CABLE.
6.2.2 Routing Rules
1. Caps for pins VDD5V, VDDQ, VDDA trace length must be less than 5 mm.
2. The trace length of OSCOUT, OSCIN must be less than 10 mm.
