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.

PIN DESCRIPTIONS
Description
Driver input pin, LVCMOS compatible.
Non-inverting driver output pin, M-LVDS levels.
Inverting driver output pin, M-LVDS levels.
Driver enable pin: When DE is low, the driver is disabled. When DE is high and DE is low or open, the
driver is enabled. If both DE and DE are open circuit, then the driver is disabled.
Driver enable pin: When DE is high, the driver is disabled. When DE is low or open and DE is high, the
driver is enabled. If both DE and DE are open circuit, then the driver is disabled.
