8.2.1 Design Requirements

Typically, in CSI-2 applications, the system trace length from the Camera (Source) to the DPHY440 device is different from that of the trace length from DPHY440 to the APU (Sink). Consequently, different pre-emphasis and equalization settings are required on the receiver and transmitter side of the device respectively.

For this design example, refer to Figure 17 and Figure 18. Shown is a CSI-2 system implementation in which the DPHY device is placed close to the Sink (APU). Here, the input trace length is about 12 inch while the output trace length is just 1 inch. The input signal characteristics assumed are shown in Table 15.

PARAMETER VALUE
Data Rate (200 Mbps to 1.5 Gbps) 1 Gbps
Input trace length 12 inch
Output trace length 1 inch
Trace width 10 mils
