DS250DF230EVM User’s Guide
The DS250DF230 is a four-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 DS250DF230 independently locks to serial
data rates in a continuous range from 19.6 Gbps to 25.8 Gbps or to any supported sub-rate (÷2 and ÷4).
The DS250DF230 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 DS250DF230
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 DS250DF230 implements 2x2 cross-point on each channel pair, providing the host with both
lane crossing and fanout options.
The DS250DF230 can be configured via the default SMBus slave mode or with an external EEPROM. Up
to 16 devices can share a single EEPROM. A non-disruptive on-chip eye monitor and PRBS generator
and checker functions allow for in-system diagnostics. With this kit, users can quickly evaluate the
DS250DF230 retimer performance.

standard 6-pin EEPROM (XU1). SigCon Architect cannot directly program the EEPROM. The EEPROM
Hex File can be burned on the EEPROM via I2C communication (i.e. AARDVARK or equivalent interface
adapter). The EEPROM control settings are described in greater detail below.
• Common Channel: If this box is checked, all channels receive the same configuration. Different
devices can receive different configurations, but within one device, all channels will receive the same
configuration. If this box is unchecked, then the EEPROM will store the configuration as unique
channel configurations. Each of the four channels can receive a unique configuration.
• EEPROM>256:
– This setting must be enabled if there are more than 4 EEPROM slots.
– When this box is checked, the “EEPROM Size” drop down menu is automatically populated by 512
Bytes if previously populated by 256 Bytes.
– When this box is unchecked, the “EEPROM Size” drop down menu is automatically populated by
256 Bytes. Up to 4 EEPROM slots can be programmed.
• Enable CRC: If enabled, each device will have a CRC value specific to the base header, address map
header, and data. If disabled, the CRC is not computed.
• Slot Update Details: The number of slots refers to the total number of unique SMBus register settings
to load from the EEPROM. The user can choose to update all slots, or which slot # to update the
SigCon Architect EEPROM page from.

Best Practices and Usage Tips
The following is a general procedure that should be followed when using the DS250DF230EVM in a
system.
1. Set up your data source (either BERT TX or ASIC TX) to generate a PRBS pattern of the desired data
rate.
1. Not all BERT TX sources have FIR capabilities. The DS250DF230 receiver usually does not need
much de-emphasis applied by the link partner transmitter (i.e. the BERT TX or ASIC TX). Typically
3dB of de-emphasis or 0-15% post-cursor will be adequate. If the BERT/ASIC TX has pre-cursor
capabilities, then 0-15% pre-cursor should be adequate. Most links should be operable without any
TX de-emphasis.
2. Connect the EVM in to the system. Typically this will consist of the following topology:
BERT TX or ASIC TX → SMA cables → channel_1 → Huber+Suhner cables → DS250DF230 EVM
RXn → DS250DF230 EVM TXn → Huber+Suhner cables → channel_2 → SMA cables → BERT RX or
ASIC RX
1. After making your data rate selection, push the “RESET CDR” button on the CDR tab. You only
need to press this once, provided you do not change data rate or adapt mode.
2. Check the Signal Detect and CDR lock status indicators to see if the link is established.
3. If the CDR is in locked, the CDR lock indicator on the page will turn green and display "CDR
locked."
3. Check the Horizontal Eye Opening (HEO) and Vertical Eye Opening (VEO), displayed on the Device
Status tab. The user may also go the Eye Monitor Page to plot a full eye diagram.
4. Check the Retimer Receiver’s bits received and errors by clicking "Turn ON" in the PRBS pattern
checker section of the PRBS Gen/Checker" tab. If necessary, tune the link partner transmitter’s FIR
settings to achieve the target BER.
5. Tune the Retimer TX FIR settings on the TX FIR/VOD tab. It is best to demonstrate that the return path
(Retimer TX to BERT/ASIC RX) is working first before trying to optimize the Retimer RX parameters.
One way to do this would be to test over a simple channel_1 first to prove that the Retimer can drive
data error-free into the BERT/ASIC (optimizing the Retimer TX FIR as needed) then switch to the more
difficult channel_1 while keeping channel_2 unchanged.
Things to watch for:
1. At 25-28Gbps data rates, small imperfections in the channel can be problematic. Ensure that cables
are properly torqued (not over-torqued), paddle cards are properly mated with backplane connectors,
and the BERT RX is properly aligned to the incoming data stream.
2. When adding up the total channel loss, do not forget to include the loss of the test fixture and cables.
For example, the DS250DF230 EVM board plus Huber+Suhner cables have ~4dB of insertion loss
from the device output to the Huber+Suhner cable end; and another ~4dB from the Huber+Suhner
cable end to the device input.
