JEDEC JESD22-A137 EMC Signal Integrity Verification Testing
The JESD22-A137 standard is a critical part of the semiconductor and microchip testing sector, ensuring that electronic components meet stringent electromagnetic compatibility (EMC) and signal integrity requirements. EMC testing verifies that devices operate as intended without causing harmful interference to other electronic equipment in their environment. Signal integrity ensures that signals are transmitted accurately between points within a circuit.
The JESD22-A137 test is particularly relevant for semiconductor manufacturers, module suppliers, and integrated circuit (IC) designers who need to ensure their products meet the stringent requirements set forth by this standard. This testing procedure aims to validate that devices comply with the specified emission limits under controlled conditions.
The standard covers a range of tests designed to evaluate both conducted emissions and radiated emissions from the device under test (DUT). Conducted emissions are measured using a conducted emissions test setup, while radiated emissions are assessed via a radiated emissions test. The DUT is placed in an anechoic chamber to minimize external interference during the testing process.
The primary goal of this testing is not only compliance with regulatory requirements but also to ensure product reliability and performance. Non-compliance can lead to interoperability issues, potential safety hazards, and increased warranty costs for manufacturers. By adhering to JESD22-A137 standards, companies can avoid costly recalls and maintain a reputation for high-quality products.
The testing process involves several key steps. First, the DUT is carefully prepared, ensuring all connections are secure and that the device operates as intended under test conditions. Next, the DUT is placed into an anechoic chamber, which absorbs radio waves to prevent reflections that could affect measurement accuracy. Once in place, various measurements are taken using specialized equipment designed to meet the stringent requirements of this standard.
Accurate data collection and analysis are crucial for successful JESD22-A137 testing. The test results are compared against internationally recognized standards such as ISO, ASTM, and the IEC. Compliance with these standards ensures that the DUT meets global quality and safety requirements. In addition to compliance, thorough testing also helps identify potential issues early in the design process, allowing for timely corrections.
For semiconductor manufacturers, this testing is essential during various stages of product development. It provides valuable insights into how well the device performs under real-world conditions. The test results can guide further refinement of designs and production processes to enhance performance and reliability. Additionally, compliance with JESD22-A137 standards can significantly improve a company's market position by demonstrating commitment to quality and safety.
In summary, the JESD22-A137 EMC Signal Integrity Verification Testing is a vital component of semiconductor testing that ensures devices meet stringent international standards for electromagnetic compatibility and signal integrity. By adhering to this standard, manufacturers can ensure product reliability, interoperability, and safety while enhancing their market reputation.
The comprehensive testing process involves careful preparation of the DUT, placement in an anechoic chamber, and measurement of conducted and radiated emissions against internationally recognized standards.

Scope and Methodology
The JESD22-A137 standard encompasses a wide range of tests designed to evaluate both conducted emissions and radiated emissions from semiconductor devices. The scope of this testing includes:
- Conducted Emissions Testing: This involves measuring the emission levels through conductive paths, such as cables or connectors.
- Radiated Emissions Testing: This measures the electromagnetic radiation emitted by the device under test in an anechoic chamber to ensure it does not interfere with other devices.
The methodology for JESD22-A137 testing typically involves several key steps. First, the DUT is prepared and connected to the appropriate test equipment, ensuring all connections are secure and that the device operates as intended under test conditions. Next, the DUT is placed into an anechoic chamber to minimize external interference during the testing process.
The conducted emissions test uses a conducted emissions test setup, which includes a current clamp and spectrum analyzer. The radiated emissions test uses a radiated emissions test setup, which involves placing the DUT in an anechoic chamber with a field probe to measure emitted signals.
The test results are then compared against internationally recognized standards such as ISO, ASTM, and IEC. Compliance with these standards ensures that the DUT meets global quality and safety requirements. In addition to compliance, thorough testing also helps identify potential issues early in the design process, allowing for timely corrections.
