3 Description
The DS250DF210 device is a two-channel, multi-rate
retimer with integrated signal conditioning. It is used
to extend the reach and robustness of long, lossy,
crosstalk-impaired, high-speed serial links while
achieving a bit error rate (BER) of 10-15 or less.
Each channel of the DS250DF210 independently
locks to serial data rates in a continuous range from
20.6 Gbps to 25.8 Gbps or to any supported sub-rate
(÷2 and ÷4), including key data rates such as 10.3125
Gbps and 12.5 Gbps, which allows the DS250DF210
to support individual lane Forward Error Correction
(FEC) pass-through.

5 Description (continued)
The DS250DF210 has a single power supply and minimal need for external components. These features reduce
PCB-routing complexity and BOM cost.
The advanced equalization features of the DS250DF210 include a low-jitter 3-tap transmit finite impulse
response (FIR) filter, an adaptive continuous-time linear equalizer (CTLE), and an adaptive decision feedback
equalizer (DFE). This enables reach extension for lossy interconnect and backplanes with multiple connectors
and crosstalk. The integrated CDR function is ideal for front-port optical module applications to reset the jitter
budget and retime the high-speed serial data. The DS250DF210 implements a 2x2 cross-point, providing the
host with lane crossing, fanout, and multiplexing options
The DS250DF210 can be configured either through the SMBus or through an external EEPROM. Up to 16
devices can share a single EEPROM using Common Channel format. A non-disruptive, on-chip eye monitor and
a PRBS generator or checker allow for in-system diagnostics.

6.5 Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

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