PRODUCTION DATA
GUID-6A2D35AF-6DE0-4EDE-B152-933D6D62EDD4.html#SNLS5067495 and GUID-6A2D35AF-6DE0-4EDE-B152-933D6D62EDD4.html#T4585536-20 show typical applications of the DS90UB638-Q1 for multi-camera surround view system. From GUID-6A2D35AF-6DE0-4EDE-B152-933D6D62EDD4.html#SNLS5067495, the FPD-Link III is AC-coupled external 100-nF and 47-nF capacitors for coaxial interconnects. The same AC-coupling capacitor values should be matched on the paired serializer boards. The deserializer has an internal termination. Bypass capacitors are placed near the power supply pins. At a minimum, 0.1-μF or 0.01-μF capacitors should be used for each of the core supply pins for local device bypassing. Additional bulk decoupling capacitors and ferrite beads are placed on the VDD18 supplies for effective noise suppression.
