Bypass Capacitor Placement for Optimal Performance

To ensure optimal performance, it is recommended to use high-quality ceramic bypass capacitors for the VDD, OVDD, VCM, REFH, and REFL pins. These capacitors should be positioned as close to the pins as feasible. Paying particular attention to the 0.1μF capacitor between REFH and REFL, it should be placed as near to the device as possible, ideally within 1.5mm or less. It is advised to use a size 0402 ceramic capacitor for this purpose. The larger 2.2μF capacitor between REFH and REFL can be placed at a slightly greater distance. Additionally, it is important to keep the traces connecting the pins and bypass capacitors short and wide.
