When the single differential pair of serial data is not fast enough, the technology of parallel grouping serial data channels and adding parallel clock channels for synchronization can be adopted. This is the technology used by FPD-Link. Other examples of parallel lvd using multiple LVDS pairs to synchronize with parallel clocks are channel linking and hypertransmission.
There is also the technique to increase the data throughput by grouping multiple LVDS-with-embedded-clock data channels together. However, this is not parallel LVDS because there is no parallel clock and each channel has its own clock information. An example of this technique is PCI Express where 2, 4, or 8 8b/10b encoded serial channels carry application data from source to destination. In this case the destination must employ a data synchronization method to align the multiple serial data channels.
