Faster (& More) Signaling on the Same Channel

A quick history lesson from the heart of the Silicon Valley.

We all remember the emergence of low-voltage differential signaling (LVDS) in the mid 1990s. The idea was to be able to move digital signals very high speeds to enable higher resolution monitors and better user interface experience with computing, among other things.

Two years after the introduction of LVDS, National Semiconductor — now part of Texas Instruments — created the flat-panel display link (FPD-Link) as an open standard based on LVDS.

Within five years, automotive manufacturers began adopting FPD-Link into their automotive infotainment systems for navigation and other applications. Flash forward to 2010. This is when FPD-Link 3 was introduced. The idea was to embed a bidirectional communications channel on the same differential pair, which would cut systems costs by allowing signals such as I2C and CAN to run on the same channel.

On the road, we stopped at TI/National — in the eyes of many a crucible of Silicon Valley innovation — to get an update on FPD-Link 3 from Sue Poniatowski, applications manager, and Stephen Kempainen, strategic marketing. We'll let them explain (see also a separate segment on parking-assist technologies):

    What is the significant between this and traditional automotive CAN bus which is also adopting differential signalling?
