How to Optimize Return Path

For Receiver LEQ Test with PCIe Gen5 (32GT/s), it is important to optimize Return Path (DUT Tx to BERT ED). The procedure is shown below.

Requirements for using the G0430A When testing the System, connect the G0430A between DUT Tx and ED. Refer to Chapter 2 “Connection Procedure” for how to set up the G0430A. Though the G0430A is not required for AIC Test, it is the same as the method of optimizing Return Path for System / AIC test.

CAUTION

The maximum recommended input amplitude for the IC mounted on the MAEQ-39940B EVM board is 1.0 Vp-p (differential).

The G0430A is used with Ch1 and Ch2 of the IC on the MAEQ-39904B EVM board connected in series. Therefore, if the input amplitude for Ch1 exceeds 800 mVp-p (differential), there is a risk that the input amplitude for Ch2 in the subsequent stage could exceed 1 Vp-p (differential).

By using an oscilloscope with a bandwidth of at least 50 GHz, make sure that the input waveform amplitude for the MAEQ-39904B EVM board is less than or equal to 800 mVp-p (differential).

Preparation of preset files
To optimize the Return Path, you are required to prepare preset files for MAEQ-39904B.

1. Copy the zip file from the USB flash drive to the PC or MP1900A.
   \Macom_MAEQ-39904_EQ_Preset.zip

2. Extract the zip file, and then make sure that the following 21 files
   are in the directory you specify.
   MAEQ-39904_EQ_P0.txt
   MAEQ-39904_EQ_P1.txt:
   MAEQ-39904_EQ_P19.txt
   MAEQ-39904_EQ_P20.txt

3. Click the Channel Control tab, click Load File shown in Figure 3.2-1, and select a preset file.
   

Optimization procedure

1. Refer to the “Receiver Link Equalization Test” section in the MX183000A High-Speed Serial Data Test Software Operation Manual and set up the test configuration according to the figure below. Turn on the DUT.

2. Start MX183000A, set Specification to 5.0(32.0 GT/s), and then turn off all the stresses below.
   ● SJ
   ● RJ
   ● DM
   ● CM
   

3. In the MX183000A main screen, select the Setting check box for LEQ Test, and follow the steps below:
   3a. Set PPG Starting Preset to P5.
   3b. Set DUT Initial Preset (Preset Hint Tx) to P9.
   3c. Set DUT Target Preset (Change Preset) to P9.
   3d. Click Apply.
   3e. Click Option, and then on the PPG/ED tab of the Option dialog box, set CTLE Gain to 0.0 dB.
   

4. Turn the G0430A on, load channel control parameters shown in Table A-1 from a preset file named MAEQ-39904_EQ_P0.txt first as shown in Figure 3.2-1.

5. Click Link Start.
   

6. Establish Loopback.
   6a. If Linkup Speed is not 32.0 Gbps and the LTSSM State is not
   Loopback. Active. Lead, increase the preset file number of the redriver , for example at intervals of four, EQ_P0 -> EQ_P4  > … – > EQ_P20. Each time the preset file number set to the re-driver changes, make sure that the LTSSM is in the Loopback state displayed.
   6b. If Loopback cannot be established despite the preset file number is set to EQ_P20, set the Preset values in steps 3b and 3c to P8, set the preset file number of the re-driver to EQ_P0, and then retry to check the Loopback state according to step 6a.
   6c. If Loopback cannot be established even with Preset P8, redo step 6b with the Preset values set to P7, P6, … P0.
   6d. If Loopback cannot be established even with Preset P0 in step 6c, set CTLE Gain to OFF (step 3e.) and redo step 3 to 6c.
   
   6e. If Loopback is established according to steps 6a to 6d, check the Preset values of MX183000A and the preset file number of the re-driver.
   6f. If Loopback cannot be established up to step 6e, remove ISI from the measuring system and retry steps 6a to 6e.
   If Loopback cannot be established by the steps above, the measurement environment may be incorrect (cable connection error, etc.) or there may be a problem with the DUT, so review the measurement environment again.

7. BER optimization
   Perform Link Training with the Preset values, CTLE Gain setting,
   and the preset file number of the re-driver specified in step 6 to
   measure BER.
   7a. Optimize EQ to find the setting that gives the optimal BER.
   7b. Set the EQ confirmed in step 6.
   7c. Run Auto Search.
   Click Operate MP1900A to switch over to MP1900A GUI.
   
   Click the Auto Search button.

Set as below and click Start:
Mode: Fine(NRZ)
Item: Threshold & Phase
CTLE Auto Adjust: OFF (if CTLE Gain setting is ON)

7d. Wait until Auto Search is completed, and then check BER.
7e. Increase the preset file number of the re-driver by 1 or 2 at a time, and then check the BER again. If the optimal preset BER numbers are detected in succession, repeat until you find the preset number at which the BER deteriorates. If an error-free condition is achieved with multiple preset file numbers, use the preset file with the middle number of a series of preset file numbers as the optimum setting.
7f. Click the Auto Search button in step 7c and check the BER again.
When an error-free condition is achieved with the steps so far, optimization of Return Path is complete successfully. Then, go to step 8. Otherwise, follow steps 7g to 7j.
7g. CTLE adjustment Adjust the CTLE Gain value or set CTLE Gain to OFF to minimize Total BER.

7i. Run Auto Search
Click Operate MP1900A to switch over to MP1900A GUI

Click the Auto Search button.

Set as below and click Start:
Mode: Fine(NRZ)
Item: Threshold & Phase
CTLE Auto Adjust: ON (if CTLE Gain setting is ON)

7j. Wait until Auto Search is completed, and then check BER.
With the steps so far, if an error is still detected, it is determined that there is an error in the Rx of the DUT.

8. Confirm the setting parameters for optimization.
   These parameters for optimization are determined according to the procedure above (steps 1-7), as shown below:
   ● Preset setting confirmed in step 6.
   DUT Initial Preset (Preset Hint Tx)
   DUT Target Preset (Change Preset)
   
   ● Threshold, Phase, and G0430A settings confirmed in step 7. CTLE setting is effective only when step 7i is followed.
   
   Now, the Return Path is successfully optimized.
