3.21.1. Design Considerations
 Special attention should be paid to the pin definition of LCM/camera connectors. Assure the
SC600Y/SC600T and the connectors are correctly connected.
 MIPI are high speed signal lines, supporting maximum data rate up to 2.1Gbps. The differential
impedance should be controlled as 100Ω. Additionally, it is recommended to route the trace on the
inner layer of PCB, and do not cross it with other traces. For the same group of DSI or CSI signals, all
the MIPI traces should keep the same length. In order to avoid crosstalk, it is recommended to
maintain the intra-lane spacing as trace width and the inter-lane spacing as two times of the trace
width. Any cut or hole on GND reference plane under MIPI signals should be avoided.
 It is recommended to select a low capacitance TVS for ESD protection and the recommended
parasitic capacitance is below 1pF.
 Route MIPI traces according to the following rules:
a) The total trace length should not exceed 305mm;
b) Control the differential impedance to 100Ω±10%;
c) Control intra-lane length difference within 0.67mm;
d) Control inter-lane length difference within 1.3mm.
