OCTOBER 2018 I DESIGN007 MAGAZINE 73 Results of the eye opening are summarized in Table 2. At the receiving end with one Gbps (i.e., lower-speed grade) transmission, besides 8% attenuation caused by dielectric loss, an additional attenuation of less than 5% is caused by 1.8 inches in total serpentine length. On the other hand, at the receiving end with 10 Gbps (i.e., higher-speed grade) transmission, besides 15% attenuation caused by dielectric loss, an additional attenuation of less than Table 2: Results of the eye opening.
