Qualitas Semiconductor Selects Anritsu’s Vector Network Analyzer for High-Speed Interconnect Signal Integrity Verification

ANRITSU CORPORATION is pleased to announce that Qualitas Semiconductor Co., Ltd. (hereinafter “Qualitas”), a leading developer specializing in PHY IP solutions for high-speed interconnects, has adopted Anritsu’s ShockLine™ 4-Port Performance Vector Network Analyzer (VNA) MS46524B to enhance signal integrity verification for its high-speed interface IP development. Qualitas has significantly improved the quality and reliability of its IP solutions by establishing a verification environment that enables highly accurate, repeatable signal-integrity evaluations across the entire system, including PHY IP.

Qualitas develops high-speed interface IP solutions, including SerDes PHY IP, PCI Express® PHY IP, UCIe interconnect solutions, and Ethernet PHY IP, and it collaborates with global customers across advanced semiconductor markets in fields such as AI, data centers, automotive, and mobile systems.

As semiconductor interface technologies continue to increase data transmission speeds, system-level verification that includes the characteristics of the entire interconnect channel, such as the PCB, package, and socket, has become increasingly important, rather than just the performance of the chips. In high-speed signal environments, factors such as transmission loss, reflection, and crosstalk affect signal integrity, making precise measurement-based verification environments essential.

To address these requirements, Qualitas has adopted Anritsu’s ShockLine™ MS46524B to analyze the characteristics of high-speed interconnect channels and quantitatively verify signal integrity, based on differential S-parameter analysis and time-domain reflectometry (TDR) measurements.

The ShockLine™ MS46524B provides high-frequency measurement stability, support for mixed probe and coaxial cable environments, and high-resolution TDR measurement capabilities, enabling precise analysis of subtle impedance variations occurring in the package and PCB structures. Through this approach, Qualitas has established a verification environment that is close to the conditions of real systems, enabling it to provide the reliability required in the PHY IP development process.

Anritsu highlights the importance of signal integrity verification solutions and measurement technologies that are required in next-generation interface technology environments, and it plans to support semiconductor and high-speed interface development companies in building more efficient verification environments.
