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 multi•

point 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 SOIC-

16 package.
