Special attention should be paid to the pin definition of LCM/camera connectors. Assure the SC200L
and the connectors are correctly connected .
MIPI is high speed signal lines, supporting maximum data rate up to 1.5Gbps. The differential
impedance should be controlled to 100
Ω
. 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, a distance of 1.5 times the
trace width among MIPI signal lines is recommended. During impedance matching, do not connect
GND on different planes so as to ensure impedance consistency.
It is recommended to select a low capacitance TVS for ESD protection and the recommended
parasitic capacitance should be below 1pF.
Route MIPI traces according to the following rules:
a) The total trace length should not exceed 75mm;
b) Control the differential impedance to 100
Ω
±10%;
c) Control intra-lane length difference within 0.5mm;
d) Control inter-lane length difference within 1.3 mm.
