How Should We Go About Initiating Services

Our experience dramatically helps customers accelerate their signal integrity prowess, but it takes a bit of systematic effort. First, we need a mutual NDA to have a substantive first meeting. Otherwise, we can speak in general terms, which mostly doesn’t work. Next, it is a good idea to start a document outlining prioritized signal integrity issues existing presently, also future proofed for next generation activity. Common signal integrity issues include: Material ID Via design TDR impedance of transmission lines using both EDA, time domain S-parameters, and direct TDR impedance analysis Differential analysis and differential via design methodology Benchmarking EDA tools like Clarity and HFSS Signal Integrity training for either measurements or EDA simulation tools Measurement analysis using either TDR or S-parameters Elements of stack-up design Advancing simulation to measurement methodology. We initially help our customers with an option to add consulting packages for specific objectives. It would be good to have team consensus on max frequency, data rates, coding, etc. The Wild River engineering team looks forward to working with you folks.

Why Forward Couplers Fall Short for Aggressor Injection in SERDES Testing

Rethinking Aggressor Injection: Skip the Forward Couplers Forward couplers are often proposed for aggressor signal injection in SERDES testing—but they introduce fundamental limitations that make them unsuitable for accurate crosstalk modeling. In real-world backplane and serial link systems, forward couplers are not present. These systems are inherently wideband, and their transmission characteristics—defined by PCB traces, vias, and dielectric loss—are vastly different from what a directional coupler can emulate. Crosstalk behavior in practical PCB systems is shaped by dielectric and conductor losses, along with layout-specific factors like via structures and connector transitions. These are critical variables for accurate Channel Operating Margin (COM) and serial link analysis, and none of them are captured using forward couplers. Instead, consider using a purpose-built PCB crosstalk platform like XTALK-56. It’s designed to replicate realistic inter-symbol interference (ISI) and crosstalk characteristics across a range of channel types. XTALK-56 includes: True PCB-based crosstalk coupling Via and backplane/connector emulation Return loss degradation structures Support for simultaneous clock and data interference By modeling loss and crosstalk together, XTALK-56 allows engineers to quantify how these impairments affect transmission reach and perform SERDES design of experiments (DoE) with precision. Crucially, adding noise to the RX input is not crosstalk—it’s just noise. Forward couplers inject deterministic jitter profiles that don’t match the stochastic nature of real PCB crosstalk. XTALK-56, by contrast, introduces jitter in a way that reflects actual high-speed PCB transmission paths. If your goal is to evaluate the true impact of crosstalk on SERDES performance, I strongly recommend exploring XTALK-56 over any forward coupler-based approach.

Are your test platforms available for evaluation?

Wild River Technology does not typically offer test platforms for general evaluation. However, in select cases, we may provide access to a test platform based on the specific needs and qualifications of the project. Evaluation opportunities are reviewed individually and may depend on factors such as technical alignment, timeline, and intended use. If you're interested in evaluating one of our platforms, please reach out to Wild River Technology Sales to discuss your requirements. We’re happy to explore whether a tailored evaluation arrangement makes sense for your situation.

How Should We Go About Initiating Services
Wild River Technology helps teams accelerate their signal integrity capabilities through structured collaboration. We begin with an NDA and a prioritized review of current and next-gen SI challenges, offering consulting support tailored to your design and measurement needs.
Why Forward Couplers Fall Short for Aggressor Injection in SERDES Testing
Forward couplers fall short in SERDES testing, failing to replicate real PCB crosstalk. XTALK-56 offers a more accurate, loss-aware platform for evaluating true transmission impairments and jitter behavior.
Are your test platforms available for evaluation?
Test platforms are not typically available for evaluation, but in select cases, Wild River Technology may consider it based on project needs. Contact Sales to inquire.
