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 common in multipoint configurations due to unterminated stubs.
The DS91M047 accepts LVTTL/LV
CMOS 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 tha...
