APPLICATION INFORMATION (continued)
Figure 12. 16-Bit Bus Extension With Parity
Figure 13 represents LVDS serdes in an application as a virtual backplane transceiver (VBT). The concept of a
VBT can be achieved by implementing individual LVDS serdes chipsets in both directions of subsystem
serialized links.
Depending on the application, the designer will face varying choices when implementing a VBT. In addition to the
devices shown in Figure 13, functions such as parity and delay lines for control signals could be included. Using
additional circuitry, half-duplex or full-duplex operation can be achieved by configuring the clock and control lines
properly.
The designer may choose to implement an independent clock oscillator at each end of the link and then use a
PLL to synchronize LVDS serdes's parallel I/O to the backplane bus. Resynchronizing FIFOs may also be
required.
