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 common 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 common 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 SOIC16 package.
