Demand for the PCIe high-speed interface has significantly increased with the continuous development of semiconductor technology. PCIe 5.0 has quadrupled bandwidth over the previous standard in just a few years, with PCIe 6.0 expected to debut soon. Although the higher data rate of the chipset offers convenience to users, the development and design of the entire system has become increasingly more difficult. Specifically, the attenuation and the interference of noise in the motherboard eventually makes the signal between the CPU chip and the endpoints unable to be accurately transmitted and can even cause compatibility problems.<\/p>\n
Phison\u2019s Redriver IC PS7101 effectively reduces the compatibility problems that may occur when connecting with the CPU chip and the endpoints. The company\u2019s Flip-Chip package design further reduces the signal reflection and crosstalk interference caused by the IC package and improves the ability of heat dissipation. PS7101 provides multi-band independent compensation, which can be easily adapted to different cable or PCB materials, allowing users to adjust separately to achieve the best compensation for loss.<\/p>\n
In addition, Phison provides an exclusive patented Auto Tuning Tool. This set of tools can automatically set different gain parameters in the Redriver for customer\u2019s development environment, collect the results of the signal, and optimize with AI technology to find the best parameters for the corresponding environment. The Auto Tuning Tool allows developers quickly adjust to find the best Redriver gain parameter that suits their motherboard environment.<\/p>\n

<\/p>\n As major CPU and motherboard chipset manufacturers continue to push the speed of PCIe to the limit, other technologies need to keep up to fulfill the ecosystem. Typically, this is achieved through huge investment and with uncertainty in product compatibility. Phison has been committed to the research and development of high-speed transmission interface technology for several years.<\/p>\n After confirming customer needs, Phison designed IC specifications, invested in IC development, completed PS7101 engineering samples, and began production in less than 8 months. The company conducted rigorous tests on ICs to make sure that the features required by each IC meet the requirements of the specifications, and at the same time, ensured compatibility with the complex and diverse environment of transmission between different CPU chips and various PCIe 5.0 devices.<\/p>\n![\"\"](\"https:\/\/phisonblog.com\/wp-content\/uploads\/2021\/08\/1149821_PCIe-5-Redriver-Eye-gfx-for-PR_1920x1200_081121.jpg\")
