Among many other benefits, signal distribution with multipoint networks reduces connector size and cable diameter, lowers conductor count and PCB thickness, and ultimately decreases system cost. These benefits come at the cost of signal integrity, maximum transmission reach and speed. When satisfactory signal integrity, transmission reach or speed using multipoint networks cannot be achieved, signal distribution with point-to-point links may be the only option. Signal distribution with point-to-point links is accomplished using fan-out buffers as illustrated in Figure 10-1.
The current M-LVDS portfolio offers two 1:4 fan-out buffers/signal repeaters: DS91M124 and DS91M125.
The DS91M124 is the fan-out buffer with an LVCMOS input and four M-LVDS outputs. It provides LVCMOS-to-M-LVDS level translation and 1:4 signal distribution. It is best suited for taking an LVCMOS signal from a local signal source and distributing it to local or remote M-LVDS receivers.
The DS91M125 is the fan-out buffer with an LVDS input and four M-LVDS outputs. It can take an LVDS compatible signal from a local or remote source via a point-to-point or multidrop link and distribute it to four local or remote M-LVDS receivers or M-LVDS multipoint networks.
In addition to M-LVDS fan-out buffer, there are also several LVDS and Bus LVDS fan-out buffers. Table 10-1 provides the summary.
