What is the IEEE P370 standard?

IEEE P370 standard

The IEEE P370 standard, titled “Standard Test Methods for Characterizing High-Speed Board-to-Board Connectors,” aims to provide a comprehensive set of guidelines and methodologies for testing and characterizing high-speed board-to-board connectors. These connectors are crucial components in electronic systems that facilitate the transmission of high-frequency signals between printed circuit boards (PCBs) or other electronic modules.
Specifically, the standard focuses on addressing the challenges associated with modeling and simulating high-speed PCB interconnects when dealing with broadband signals, especially up to 50 GHz. This includes considerations for signal integrity, impedance control, and minimizing signal distortion at these high frequencies.

Key aspects of the standard may include but are not limited to:

  1. S-Parameter Measurement Techniques: This may cover detailed methodologies for measuring S-parameters, which are essential for characterizing the frequency-dependent behavior of high-speed interconnects. The standard may specify procedures for performing time-domain reflectometry (TDR) and vector network analyzer (VNA) measurements to extract S-parameters accurately over a wide frequency range.
  2. Connectors’ Signal Integrity Considerations: Given the importance of signal integrity in high-speed interconnects, the standard might provide guidance on evaluating parameters such as insertion loss, return loss, impedance matching, and crosstalk. These considerations are crucial for ensuring reliable signal transmission and minimizing distortion at high frequencies.
  3. Fixture Design and Calibration: The standard may include recommendations for designing test fixtures and calibration procedures to account for measurement uncertainties and ensure accurate and repeatable results. Proper fixture design and calibration are essential for minimizing parasitic effects and obtaining precise measurements of connector performance.
  4. Broadband Testing Approaches: Since high-speed applications often operate in a wide frequency range, the standard likely addresses the need for broadband testing approaches. This could involve discussing measurement techniques and equipment capabilities necessary to effectively test connectors and characterize their performance across a broad frequency spectrum.
  5. Consistent Terminology and Reporting: To promote consistency and clarity in testing and documentation, the standard may offer guidance on terminology and reporting formats. This helps ensure that test results and performance data from different sources can be easily compared and interpreted within the industry.
  6. Compliance Verification Procedures: The standard might outline procedures for verifying compliance with its requirements, including methods for assessing whether a particular connector meets the specified performance criteria and test methodologies.

Overall, the IEEE P370 standard serves as a vital resource for designers, manufacturers, and test engineers involved in developing high-speed electronic systems. By providing detailed methodologies, recommended practices, and standardized testing approaches, the standard aims to facilitate the accurate characterization and reliable performance assessment of high-speed board-to-board connectors under broadband signal conditions, ultimately contributing to the advancement of high-speed interconnect technologies.

Test Structures of IEEE P370 standard

IEEE P370 emphasizes using standardized test structures to ensure that S-parameter results are consistent across different engineering setups. This standardization is vital for reproducibility and accuracy in measurements.

1. 2x-thru Configuration:
Among the recommended test structures, the 2x-thru configuration is highlighted for its effectiveness in de-embedding processes, offering a solid basis for precise measurements.

2x-thru Configuration

For the 2x-thru configuration, one fundamental parameter is the characteristic impedance (Z0), which ideally should match that of the system or device under test (DUT). The reflection coefficient ((\Gamma)) can be calculated using:

[ \Gamma = \frac{Z_{L} – Z_{0}}{Z_{L} + Z_{0}} ]

where (Z_{L}) is the load impedance. For a perfectly matched system, (\Gamma = 0), indicating no reflection.

2.Line and Beatty Standards: 
The standard introduces two essential structures for calibration and fixture de-embedding verification. The line structure aids in determining S-parameters through its ABCD parameters, while the Beatty structure, with its distinct return loss and insertion loss spectrum, serves as a crucial tool for instrument calibration.

  • Line Structure: The S-parameters of a transmission line can be derived from its ABCD parameters as follows:

    [ S_{21} = S_{12} = \frac{2}{A + B/Z_{0} + C Z_{0} + D} ]

    [ S_{11} = S_{22} = \frac{A + B/Z_{0} – C Z_{0} – D}{A + B/Z_{0} + C Z_{0} + D} ] 

    assuming a symmetric structure where (S_{11} = S_{22}) and (S_{21} = S_{12}).

  • Beatty Standard: The resonant frequency ((f_{r})) of the Beatty standard can be approximated by:

    [ f_{r} = \frac{1}{2\pi\sqrt{LC}} ]

    where (L) is the inductance and (C) is the capacitance of the resonant cavity.

    Beatty Standard

De-embedding Procedures

Critical Role of De-embedding:
De-embedding is a key procedure within IEEE P370, which involves using a library of gold-standard S-parameters for predefined test structures to isolate the DUT’s pure S-parameters from the measured data. This process enhances the accuracy of S-parameter data and supports more reliable simulations.
The de-embedding process involves removing the effects of the test fixture or structure from the measured S-parameters. If (S_{measured}) represents the combined S-parameters of the DUT and the test structure, and (S_{test}) represents the S-parameters of the test structure alone, the pure DUT S-parameters ((S_{DUT})) can be extracted by:

[ S_{DUT} = f(S_{measured}, S_{test}) ]

The specific formula for (f(\cdot)) depends on the de-embedding method used, which could range from simple subtraction in the linear domain to more complex matrix operations.

S-parameter Quality Metrics

  • Causality:
    Ensures that the S-parameters do not introduce causal artifacts in the time-domain response when used to construct an impulse response. This metric checks the temporal consistency of the S-parameters.
    Causality implies that the system’s response cannot precede the input stimulus. Within the frequency spectrum, this is associated with the Hilbert transformation guaranteeing that the real and imaginary segments of the scattering parameters adhere to the principles of the Kramers-Kronig relations.
  • Reciprocity:
    Relates to the symmetrical nature of the S-parameter matrix for reciprocal DUTs, indicating that the matrix should mirror its own transpose. This property is fundamental for passive networks.For a reciprocal network, (S_{ij} = S_{ji}). This means if signal travels from port i to port j the same way it would from j to i, which can be mathematically represented as:

    [S_{12} = S_{21}]

  • Passivity:
    Asserts that the S-parameters must not be influenced by the strength of the input signal, emphasizing the passive behavior of the network. This ensures that the network does not generate energy.A passive network cannot generate energy, implying that all eigenvalues of the S-parameter matrix must have magnitudes less than or equal to 1:

    [ |eigenvalues(S)| \leq 1 ]

    By establishing these rigorous criteria, the IEEE P370 standard equips designers and engineers with the confidence that their S-parameter data for components or passive structures integrated into PCBs will produce accurate and consistent results in simulations. This approach addresses the challenge of inconsistent S-parameter data, facilitating more reliable and precise analyses in high-frequency signal integrity.
