Abstract :
As the data rate continuous increasing, in order to avoid signal reflection between a magnetic recording head and a read/write driver on hard disk drive interconnects (HDDIs), a practical approach, windowing, used to keep low insertion loss causes the higher crosstalk between lines. In this work, the crosstalk on idealized HDDI with percent variation of windowing is investigated. The crosstalk based on the scattering parameters is calculated by using the full wave simulation software. From the result, it is found that both of the crosstalk and the characteristic impedance increase with the increasing window percentage, while the insertion loss increased. However, the increasing window pitch of 50% windowed TSAI to 8 mm can suppress the crosstalk up to 11 dB and 39 dB at low and high frequency regions, respectively when compared with the conventional TSAI.
