FEATURES  
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.  
2
DC - 125 MHz / 250 Mbps Low Jitter, Low  
Skew, Low Power Operation  
Conforms to TIA/EIA-899 M-LVDS Standard  
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.  
Controlled Transition Times (2 ns typ)  
Minimize Reflections  
8 kV ESD on M-LVDS Pins Protects Adjoining  
Components  
Flow-Through Pinout Simplifies PCB Layout  
Industrial Operating Temperature Range  
(40°C to +85°C)  
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  
together and control the TRI-STATE outputs. The DE  
and DE inputs are common to all four drivers.  
APPLICATIONS  
Multidrop / Multipoint Clock and Data  
Distribution  
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)  
and MicroTCA (μTCA, uTCA) Backplanes  
alternative for high speed multipoint interface  
applications. It is packaged in a space saving SOIC-  
16 package.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance  
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may  
reference these types of products as "Pb-Free".  
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.  
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based  
flame retardants must also meet the <=1000ppm threshold requirement.  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.
