DS91M047 Datasheet | National Semiconductor

Description The DS91M047 is a high-speed quad M-LVDS line driver designed for driving clock or data signals to up to four multipoint networks. M-LVDS (Multipoint LVDS) is a new family of bus interface devices based on LVDS technology specifically designed for multipoint and multidrop cable and backplane applications. It differs from standard LVDS in providing increased drive current to handle double terminations that are required in multipoint applications. Controlled transition times minimize reflections that are mon in multipoint configurations due to unterminated stubs. The DS91M047 accepts LVTTL/LVCMOS input levels and translates them to M-LVDS signal levels with transition times of greater than 1 ns. The device provides the DE and DE inputs that are ANDed together and control the TRI-STATE outputs. The DE and DE inputs are mon to all four drivers. The DS91M047 has a flow-through pinout for easy PCB layout. The DS91M047 provides a new alternative for high speed multipoint interface applications. It is packaged in a space saving SOIC-16 package.
