High-speed parallel data transmission utilizing a flex-rigid concept
2005 (English)Conference paper (Refereed)
Transmission lines utilizing microstrips on a flex-foil with low dielectric loss (tanδ = 0.002) have been simulated to compare with the transmission lines laminated with a rigid part, a so-called flex-rigid structure. At high speeds, even solders, pads and connectors affect the signal integrity because of their parasitic effects. The flex-rigid structure does not require these extra parts, resulting in good signal integrity and thus high data transfer rates. Another advantage with a flexible cable is that dense parallel microstrips can easily be designed. Although many wired data communications utilize serial techniques like Serial AT Attachment (SATA), Universal Serial Bus (USB) and Firewire, the serial data link has its limitations when very high data speeds are required. With a parallel data transmission technique, the data transfer rate can be raised to a very high speed. However, a parallel data transmission technique has some disadvantages such as crosstalk and skew between the signals which must be considered.
