APPLICATIONS
•
•
High-speed active copper cable modules and
FR-4 backplane in communication systems
10GE, 10G-KR, FC, SAS, SATA 3/6 Gbps (with
OOB detection), InfiniBand, CPRI, RXAUI and
many others.
The DS100BR111 inputs feature a powerful 4-stage
continuous time linear equalizer (CTLE) to provide a
boost of up to +36 dB at 5 GHz and open an input
eye that is completely closed due to inter-symbol
interference (ISI) induced by the interconnect
mediums such as an FR-4 backplane or AWG-30
cables. The transmitter features a programmable
output de-emphasis driver with up to -12 dB and
allows amplitude voltage levels to be selected from
700 mVp-p to 1200 mVp-p to suit multiple application
scenarios.
When configured as a 10G-KR repeater, the
DS100BR111 allows the KR host and the end point to
optimize the full link by adjusting transmit and receive
equalizer
coefficients
using
back-channel
communication techniques specified by the 802.3ap
standard.
The programmable settings can be applied via pin
contol, SMBus (I2C) protocol or an external
EEPROM. When operating in the EEPROM mode,
the configuration information is automatically loaded
on power up – This eliminates the need for an
external microprocessor or software driver.
Part of National's PowerWise family of energy
efficient devices, the DS100BR111 consumes just 65
mW/channel (typical), and allow the option to turn-off
unused channels. This ultra low power consumption
eliminates the need for external heat sinks and
simplifies thermal management in active cable
applications.

LVCMOS inputs without the “Float” conditions must be driven to a logic low or high at all times or operation is not guaranteed. Unless
the "Float" level is desired; 4-Level input pins require a minimum 1K resistor to GND, VDD (in 2.5V mode), or VIN (in 3.3V mode).Input
edge rate for LVCMOS/FLOAT inputs must be faster than 50 ns from 10–90%.
Setting VOD_SEL = High in SMBus Mode will force the SMBus Address = B0'h
DS100BR111 OUTA is limited to 700mV in pin mode.

The DS100BR111 is a high performance circuit capable of delivering excellent performance. Careful attention
must be paid to the details associated with high-speed design as well as providing a clean power supply. Refer
to the information below and Revision 4 of the LVDS Owner's Manual for more detailed information on high
speed design tips to address signal integrity design issues.
The control pins have been enhanced to have 4 different levels and provide a wider range of control settings.

NOTE
4-Level IO pins require a 1K resistance to GND or VDD/VIN. It is possible to tie mulitple 4level IO pins together with a single resistor to GND or VDD/VIN. When multiple IOs are
connected in parallel, the resistance to GND or VDD/VIN should be adjusted to
compensate. For 2 pins the optimal resistance is 500 Ohms, 3 pins = 330 Ohms, and 4
pins = 250 Ohms.
NOTE
For 2.5V mode the control pin logic 1 level is VDD (pins 21 and 22), in 3.3V mode the
control pin logic 1 level is defined by VIN (pin 15).

APPLICATIONS INFORMATION
4-Level Input Configuration Guidelines
The 4-level input pins utilize a resistor divider to help set the 4 valid levels. There is an internal 30K pull-up and a
60K pull-down connected to the package pin. These resistors, together with the external resistor connection
combine to achieve the desired voltage level. Using the 1K pull-up, 1K pull-down, no connect, and 20K pull-down
provide the optimal voltage levels for each of the four input states.

Typical 4-Level Input Thresholds
– Level 1 - 2 = 0.2 VIN or VDD
– Level 2 - 3 = 0.5 VIN or VDD
– Level 3 - 4 = 0.8 VIN or VDD
In order to minimize the startup current associated with the integrated 2.5V regulator the 1K pull-up / pull-down
resistors are recommended. If several 4 level inputs require the same setting, it is possible to combine two or
more 1K resistors into a single lower value resistor. As an example; combining two inputs with a single 500Ω
resistor is a good way to save board space.
10G-KR Configuration Guidelines
When configured in "KR Mode", using either the VOD_SEL pin setting or SMBus register control, the
DS100BR111 is designed to operate transparently within a KR backplance channel environment. Installing a
DS100 repeater within the KR backplane channel splits the total channel attenuation into two parts. Ideally the
repeater can be placed near the middle of the channel maximizing the signal to noise ratio across the
bidirectional interface.
In order to maximize the 10G-KR solution space, the 802.3ap specification calls for an optimization of the
transmit signal conditioning coefficients based on feedback for the KR receiver. Setting the DS100BR111 active
CTLE to compensate for the channel loss from each of the KR transmitters will reduce the transmit and receive
equalization settings required on the KR physical layer devices. This central location keeps a larger S/N raito at
all points in the channel, extending the available solution space and increasing the overall margin of almost any
channel.
PCB Layout Guidelines
The CML inputs and outputs have been optimized to work with interconnects using a controlled differential
impedance of 85 - 100Ω. It is preferable to route differential lines exclusively on one layer of the board,
particularly for the input traces. The use of vias should be avoided if possible. If vias must be used, they should
be used sparingly and must be placed symmetrically for each side of a given differential pair. Whenever
differential vias are used the layout must also provide for a low inductance path for the return currents as well.
Route the differential signals away from other signals and noise sources on the printed circuit board. See
SNOA401Q AN-1187 for additional information on WQFN packages.
Different transmission line topologies can be used in various combinations to achieve the optimal system
performance. Impedance discontinuities at vias can be minimized or eliminated by increasing the swell around
each hole and providing for a low inductance return current path. When the via structure is associated with thick
backplane PCB, further optimization such as back drilling is often used to reduce the detrimental high frequency
effects of stubs on the signal path.

Feed 3.3V supply into VIN pin. Local 1.0 uF decoupling at VIN is recommended.
See information on VDD bypass below.
SDA and SCL pins should connect pull-up resistor to VIN

11. SDA and SCL pins connect pull-up resistor to VDD for 3.3V uC SMBus IO
12. Any 4-Level input which requires a connection to "Logic 1" should use a 1K resistor to VIN
NOTE
The DAP (bottom solder pad) is the GND connection.
Power Supply Bypass
Two approaches are recommended to ensure that the DS100BR111 is provided with an adequate power supply.
First, the supply (VDD) and ground (GND) pins should be connected to power planes routed on adjacent layers
of the printed circuit board. The layer thickness of the dielectric should be minimized so that the VDD and GND
planes create a low inductance supply with distributed capacitance. Second, careful attention to supply
bypassing through the proper use of bypass capacitors is required. A 0.1 μF bypass capacitor should be
connected to each VDD pin such that the capacitor is placed as close as possible to the device. Smaller body size
capacitors can help facilitate proper component placement.
System Management Bus (SMBus) and Configuration Registers
The System Management Bus interface is compatible to SMBus 2.0 physical layer specification. ENSMB must be
pulled high to enable SMBus mode and allow access to the configuration registers.
The DS100BR111 has AD[3:0] inputs in SMBus mode. These pins are the user set SMBus slave address inputs.
When pulled low the AD[3:0] = 0000'b, the device default address byte is B0'h. Based on the SMBus 2.0
specification, this configuration results in a 7-bit slave address of 1011000'b. The LSB is set to 0'b (for a WRITE),
thus the 8-bit value is 1011 0000'b or B0'h. The device address byte can be set with the use of the AD[3:0]
inputs.
Shown in the form of an expression:
Slave Address [7:4] = The DS100BR111 hardware address (1011'b) + Address pin AD[3]
Slave Address [3:1] = Address pins AD[2:0]
Slave Address [0] = 0'b for a WRITE or 1'b for a READ
Slave Address Examples:
• AD[3:0] = 0001'b, the device slave address byte is B2'h
– Slave Address [7:4] = 1011'b + 0'b = 1011'b or B'h
– Slave Address [3:1] = 001'b
– Slave Address [0] = 0'b for a WRITE
• AD[3:0] = 0010'b, the device slave address byte is B4'h

TRANSFER OF DATA VIA THE SMBus
During normal operation the data on SDA must be stable during the time when SCL is High.
There are three unique states for the SMBus:
START: A High-to-Low transition on SDA while SCL is High indicates a message START condition.
STOP: A Low-to-High transition on SDA while SCL is High indicates a message STOP condition.
IDLE: If SCL and SDA are both High for a time exceeding tBUF from the last detected STOP condition or if they
are High for a total exceeding the maximum specification for tHIGH then the bus will transfer to the IDLE state.
SMBus TRANSACTIONS
The device supports WRITE and READ transactions. See Table 9 for register address, type (Read/Write, Read
Only), default value and function information.

EEPROM Modes in DS100BR111 Devices
The DS100BR111 supports reading directly from an external EEPROM device by implementing SMBus Master
mode. When using the SMBus master mode, the DS100 will read directly from specific location in the external
EEPROM. When designing a system for using the external EEPROM, the user needs to follow these specific
guidelines.
• Set the DS100BR111 into SMBus Master Mode
– Float ENSMB (PIN 3)
• The external EEPROM device must support 400 KHz operation
• The external EEPROM device address byte must be 0xA0'h
• Set the AD[3:0] inputs for SMBus address byte. When the AD[3:0] = 0000'b, the device address byte is B0'h.
• Based on the SMBus 2.0 specification, a device can have a 7-bit slave address of 1010 000'b. The LSB is set
to 0'b (for a WRITE). The bit mapping for SMBus is listed below:
– [7:5] = Reserved Bits from the SMBus specification
– [4:1] = Usable SMBus Address Bits
– [0] = Write Bit
• The DS100BR111 devices have AD[3:0] inputs in SMBus mode (pins 1, 2, 9, 10). These pins set SMBus
slave address. When the AD[3:0] = 0001'b, the device address byte is B2'h.
– [7:5] = Default to 3b'101
– [4:1] = Address of 4'b0001
– [0] = Write Bit, 1'b0
• The device address can be set with the use of the AD[3:0] input up to 16 different addresses. Use the
example below to set each of the SMBus addresses.
– AD[3:0] = 0001'b, the device address byte is B2'h
– AD[3:0] = 0010'b, the device address byte is B4'h
– AD[3:0] = 0011'b, the device address byte is B6'h
– AD[3:0] = 0100'b, the device address byte is B8'h
• The master implementation in the DS100BR111 supports multiple devices reading from 1 EEPROM. When
tying multiple devices to the SDA and SCL pins, use these guidelines:
– Use adjacent SMBus addresses for the 4 devices
– Use a pull-up resistor on SDA; value = 4.7KΩ
– Use a pull-up resistor on SCL: value = 4.7KΩ
– Daisy-chain READEN# (pin 17) and DONE# (pin18) from one device to the next device in the sequence
1. Tie READEN# of the 1st device in the chain (U1) to GND
2. Tie DONE# of U1 to READEN# of U2
3. Tie DONE# of U2 to READEN# of U3
4. Tie DONE# of U3 to READEN# of U4
5. Optional: Tie DONE# of U4 to a LED to show each of the devices have been loaded successfully
Master EEPROM Mode in the DS100BR111
Below is an example of a 2 kbits (256 x 8-bit) EEPROM in hex format for the DS100BR111 device. The first 3
bytes of the EEPROM always contain a header common and necessary to control initialization of all devices
connected to the I2C bus. CRC enable flag to enable/disable CRC checking. There is a MAP bit to flag the
presence of an address map that specifies the configuration data start in the EEPROM. If the MAP bit is not
present the configuration data start address is derived from the DS100BR111 address and the configuration data
size. A bit to indicate an EEPROM size > 256 bytes is necessary to properly address the EEPROM. There are 37
bytes of data size for each DS100BR111 device.

CRC-8 based on 40 bytes of
data in this shaded area
Insert the CRC value here
MAX EEPROM Burst = 32
CRC Polynomial = 0x07
Figure 7. Typical EEPROM Data Set
The CRC-8 calculation is performed on the first 3 bytes of header information plus the 37 bytes of data for the
DS100BR111 or 40 bytes in total. The result of this calculation is placed immediately after the DS100BR111 data
in the EEPROM which ends with "5454". The CRC-8 in the DS100BR111 uses a polynomial = x8 + x2 + x + 1
In SMBus master mode the DS100BR111 reads its initial configuration from an external EEPROM upon powerup. Some of the pins of the DS100BR111 perform the same functions in SMBus master and SMBus slave mode.
Once the DS100BR111 has finished reading its initial configuration from the external EEPROM in SMBus master
mode it reverts to SMBus slave mode and can be further configured by an external controller over the SMBus.
The connection to an external SMBus master is optional and can be omitted for applications were additional
security is desirable. There are two pins that provide unique functions in SMBus master mode.
• DONE#
• READEN#
When the DS100BR111 is powered up in SMBus master mode, it reads its configuration from the external
EEPROM when the READEN# pin goes low. When the DS100BR111 is finished reading its configuration from
the external EEPROM, it drives the DONE# pin low. In applications where there is more than one DS100BR111
on the same SMBus, bus contention can result if more than one DS100BR111 tries to take control of the SMBus
at the same time. The READEN# and DONE# pins prevent this bus contention. The system should be designed
so that the READEN# pin from one DS100BR111 in the system is driven low on power-up. This DS100BR111
will take command of the SMBus on power-up and will read its initial configuration from the external EEPROM.
When it is finished reading its configuration, it will drive the DONE# pin low. This pin should be connected to the
READEN# pin of another DS100BR111. When this DS100BR111 senses its READEN# pin driven low, it will take
command of the SMBus and read its initial configuration from the external EEPROM, after which it will set its
DONE# pin low. By connecting the DONE# pin of each DS100BR111 to the READEN# pin of the next
DS100BR111, each DS100BR111 can read its initial configuration from the EEPROM without causing bus
contention.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
