FEATURES
DESCRIPTION
The DS15BR400/DS15BR401 are four channel LVDS
buffer/repeaters capable of data rates of up to 2
Gbps. High speed data paths and flow-through pinout
minimize internal device jitter and simplify board
layout, while pre-emphasis overcomes ISI jitter
effects from lossy backplanes and cables. The
differential inputs interface to LVDS, and Bus LVDS
signals such as those on TI's 10-, 16-, and 18- bit
Bus LVDS SerDes, as well as CML and LVPECL.
The differential inputs and outputs of the DS15BR400
are internally terminated with 100Ω resistors to
improve performance and minimize board space. The
DS15BR401 does not have input termination
resistors. The repeater function is especially useful
for boosting signals for longer distance transmission
over lossy cables and backplanes.

APPLICATION INFORMATION
INTERNAL TERMINATIONS
The DS15BR400 has integrated termination resistors on both the input and outputs. The inputs have a 100Ω
resistor across the differential pair, placing the receiver termination as close as possible to the input stage of the
device. The LVDS outputs also contain an integrated 100Ω ohm termination resistor, this resistor is used to
minimize the output return loss and does not take the place of the 100 ohm termination at the inputs to the
receiving device. The integrated terminations improve signal integrity and decrease the external component
count resulting in space savings. The DS15BR401 has 100Ω output terminations only.
OUTPUT CHARACTERISTICS
The output characteristics of the DS15BRB400/DS15BR401 have been optimized for point-to-point backplane
and cable applications, and are not intended for multipoint or multidrop signaling.
POWERDOWN MODE
The PWDN input activates a hardware powerdown mode. When the powerdown mode is active (PWDN=L), all
input and output buffers and internal bias circuitry are powered off. When exiting powerdown mode, there is a
delay associated with turning on bandgap references and input/output buffer circuits as indicated in the LVDS
Output Switching Characteristics.
Upon asserting the power down function (PWDN = Low), and if the Pre-emphasis feature is enable, it is possible
for the driver output to source current for a short amount of time lifting the output common mode to VDD. To
prevent this occurrence, a load discharge pull down path can be used on either output (1 kΩ to ground
recommended). Alternately, a commonly deployed external failsafe network will also provide this path (see
INPUT FAILSAFE BIASING). The occurrence of this is application dependant, and parameters that will effect if
this is of concern include: AC coupling, use of the powerdown feature, presence of the discharge path, presence
of the failsafe biasing, the usage of the pre-emphasis feature, and input characteristics of the downstream LVDS
Receiver.
PRE-EMPHASIS
Pre-emphasis dramatically reduces ISI jitter from long or lossy transmission media. One pin is used to select the
pre-emphasis level for all outputs, off or on. The pre-emphasis boost is approximately 6 dB at 750 MHz.
Table 1. Pre-emphasis Control Selection Table
PEM
Pre-Emphasis

Off
On
INPUT FAILSAFE BIASING
Failsafe biasing of the LVDS link should be considered if the downstream Receiver is ON and enabled when the
source is in TRI-STATE, powered off, or removed. This will set a valid known input state to the active receiver.
This is accomplished by using a pull up resistor to VDD on the ‘plus’ line, and a pull down resistor to GND on the
‘minus’ line. Resistor values are in the 750 Ohm to several kΩ range. The exact value depends upon the desired
common mode bias point, termination resistor(s) and desired input differential voltage setting. Please refer to
application note AN-1194 “Failsafe Biasing of LVDS interfaces” (SNLA051) for more information and a general
discussion.
DECOUPLING
Each power or ground lead of the DS15BR400 should be connected to the PCB through a low inductance path.
For best results, one or more vias are used to connect a power or ground pin to the nearby plane. Ideally, via
placement is immediately adjacent to the pin to avoid adding trace inductance. Placing power plane closer to the
top of the board reduces effective via length and its associated inductance.

SNLS224G –AUGUST 2006–REVISED APRIL 2013
Bypass capacitors should be placed close to VDD pins. Small physical size capacitors, such as 0402, X7R,
surface mount capacitors should be used to minimize body inductance of capacitors. Each bypass capacitor is
connected to the power and ground plane through vias tangent to the pads of the capacitor. An X7R surface
mount capacitor of size 0402 has about 0.5 nH of body inductance. At frequencies above 30 MHz or so, X7R
capacitors behave as low impedance inductors. To extend the operating frequency range to a few hundred MHz,
an array of different capacitor values like 100 pF, 1 nF, 0.03 µF, and 0.1 µF are commonly used in parallel. The
most effective bypass capacitor can be built using sandwiched layers of power and ground at a separation of 2–3
mils. With a 2 mil FR4 dielectric, there is approximately 500 pF per square inch of PCB.
The center dap of the WQFN package housing the DS15BR400 should be connected to a ground plane through
an array of vias. The via array reduces the effective inductance to ground and enhances the thermal
performance of the WQFN package.
INPUT INTERFACING
The DS15BR400 and DS15BR401 accept differential signals and allow simple AC or DC coupling. With a wide
common mode range, the DS15BR400 and DS15BR401 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 DS15BR400 inputs are internally terminated with a 100Ω resistor while the
DS15BR401 inputs are not, therefore the latter requires external input termination.

OUTPUT INTERFACING
The DS15BR400 and DS15BR401 output signals that are compliant to the LVDS standard. Their outputs can be
DC-coupled to most common differential receivers. Figure 14 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 accomodate LVDS compliant signals, it is recommended to
check respective receiver's data sheet prior to implementing the suggested interface implementation.
