feature
Note: The distance between 2450FB15K0008 and IC should be about 1.5~2mm. The differential
feed lines' impedance between2450FB15K0008 and IC is not critical as long as the length
(distance) is short(1.5~2mm). The only geometrical concern on the feed lines would be to keep the
same linewidth and length for them.
