DS25BR110 3.125 Gbps LVDS Buffer with Receive Equalization  
Check for Samples: DS25BR110

FEATURES  
DESCRIPTION  
The DS25BR110 is a single channel 3.125 Gbps  
LVDS buffer optimized for high-speed signal  
transmission over lossy FR-4 printed circuit board  
backplanes and balanced metallic cables. A fully  
differential signal path ensures exceptional signal  
integrity and noise immunity.  
2
DC - 3.125 Gbps Low Jitter, High Noise  
Immunity, Low Power Operation  
Four Levels of Receive Equalization Reduce  
ISI Jitter  
On-Chip 100Input and Output Termination  
Minimizes Insertion and Return Losses,  
Reduces Component Count, and Minimizes  
Board Space  
The DS25BR110 features four levels of receive  
equalization (EQ), making it ideal for use as a  
receiver device. Other LVDS devices with similar IO  
characteristics include the following products. The  
DS25BR120 features four levels of pre-emphasis for  
use as an optimized driver device, while the  
DS25BR100 features both pre-emphasis and  
equalization for use as an optimized repeater device.  
The DS25BR150 is a buffer/repeater with the lowest  
power consumption and does not feature transmit  
pre-emphasis nor receive equalization.  
7 kV ESD on LVDS I/O Pins Protects Adjoining  
Components  
Small 3 mm x 3 mm 8-WSON Space Saving  
Package  
APPLICATIONS  
Clock and Data Buffering  
Metallic Cable Equalization  
FR-4 Equalization  
Wide input common mode range allows the receiver  
to accept signals with LVDS, CML and LVPECL  
levels; the output levels are LVDS. A very small  
package footprint requires minimal space on the  
board while the flow-through pinout allows easy board  
layout. The differential inputs and outputs are  
internally terminated with a 100resistor to lower  
device input and output return losses, reduce  
component count, and further minimize board space.

Device Operation  
INPUT INTERFACING  
The DS25BR110 accepts differential signals and allows simple AC or DC coupling. With a wide common mode  
range, the DS25BR110 can be DC-coupled with all common differential drivers (i.e., LVPECL, LVDS, CML). The  
following three figures illustrate typical DC-coupled interface to common differential drivers. Note that the  
DS25BR110 inputs are internally terminated with a 100Ω resistor.

OUTPUT INTERFACING  
The DS25BR110 outputs signals compliant to the LVDS standard. It can be DC-coupled to most common  
differential receivers. The following figure illustrates typical DC-coupled interface to common differential receivers  
and assumes that the receivers have high impedance inputs. While most differential receivers have a common  
mode input range that can accommodate LVDS compliant signals, it is recommended to check the respective  
receiver's datasheet prior to implementing the suggested interface implementation.

(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.
