●PCB Layout for MSDL3
The following points should be considered about the wiring for PCB of MSDL3.
ï½¥ Wire for the PCB wiring pattern of high-speed channel (CLK, D0+/-, D1+/-, D2+/-) as short as possible.
ï½¥ The PCB wiring for high-speed channel must not use the through-hole.
ï½¥ Do not bend the wiring for high-speed channel squarely.
ï½¥ Make the wiring length of each high-speed channel the same length (within 0.5mm).
