ZHCSNJ7A April 2021 – February 2023 TDES954
PRODUCTION DATA
Figure 8-4 and Figure 8-5 show typical applications of the TDES954 for multi-camera surround view system. From Figure 8-4, the V3Link is AC coupled an external 33 to 100-nF or 15 to 47-nF capacitors for coaxial interconnects. For 2G operation or back channel frequency of ≤ 10 Mbps, the higher value AC-coupling capacitors 100 nF /47 nF are recommended. 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.
