FEATURES
DESCRIPTION
The DS91M047 is a high-speed quad M-LVDS line
2
DC - 125 MHz / 250 Mbps Low Jitter, Low
driver designed for driving clock or data signals to up
Skew, Low Power Operation
to four multipoint networks.
Conforms to TIA/EIA-899 M-LVDS Standard
M-LVDS (Multipoint LVDS) is a new family of bus
Controlled Transition Times (2 ns typ)
interface devices based on LVDS technology
Minimize Reflections
specifically designed for multipoint and multidrop
8 kV ESD on M-LVDS Pins Protects Adjoining
cable and backplane applications. It differs from

standard LVDS in providing increased drive current to
handle double terminations that are required in multi-
Flow-Through Pinout Simplifies PCB Layout
point applications. Controlled transition times

minimize reflections that are common in multipoint
(40°C to +85°C)
configurations due to unterminated stubs.
Available in a Space Saving SOIC-16 Package
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

and DE inputs are common to all four drivers.
High-Speed, Low Power, Short-Reach
Alternative to TIA/EIA-485/422
The DS91M047 has a flow-through pinout for easy
PCB layout. The DS91M047 provides a new
Clock Distribution in AdvancedTCA (ATCA)
alternative for high speed multipoint interface
and MicroTCA (μTCA, uTCA) Backplanes
applications. It is packaged in a space saving SOIC-
16 package.
