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.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
