Phison Introduces the World's First PCI-SIG Certified PCIe 5.0 Redriver IC PS7101

May 18, 2022

With the vigorous development of huge data, artificial intelligence, cloud computing and other fields, the system's demand for high-speed data transmission continues to rise. The CPU central processing unit is the core of high-speed signal transmission. Under the leadership of CPU chip suppliers such as Intel and AMD, the transmission interface of the system has entered the PCIe 5.0 generation, and the single-channel transmission speed has reached 32Gbps per second, which is the previous generation. 2x that of PCIe 4.0. However, in the environment of PCIe 5.0 high-speed transmission, compatibility issues such as signal attenuation and noise impact on the motherboard have become common problems and challenges faced by all system integrators. PHISON Electronics today (5/18) launched the world's first PCIe 5.0 Redriver IC PS7101 (certified through Link Link) certified by the PCI-SIG Association to help solve high-speed signal transmission between CPU and interface devices (such as SSD and display adapters, etc.) Compatibility issues.


In the generation of PCIe 5.0 high-speed transmission, whether it is desktop computers, servers, industrial computers, cables, or even notebook computers, Redriver ICs will be required. Depending on the degree of signal attenuation and the number of compensation channels, each system device will require 2 to 16 Redriver ICs. In other words, according to market research agencies, high-speed transmission signal enhancement ICs (including Redriver and Retimer ICs) will reach a market size of 50 million pieces per year in 2025.

      PHISON Electronics has long been committed to the research and development of high-speed transmission interface technology, and is one of the few IC companies in Taiwan that has independently developed PCIe 5.0 PHY physical layer IP. The PCIe 5.0 Redriver IC PS7101 launched this time adopts the Flip-Chip packaging and testing technology to reduce the signal reflection and crosstalk interference caused by IC packaging, and at the same time improve the IC heat dissipation capability, which will effectively solve the main board of PC and Server platforms. Or the high-speed transmission signal attenuation problem of the riser card. It is an IC product with high gain, high linearity, and high cost performance.

      In addition, PHISON's PCIe 5.0 Redriver IC PS7101 provides multi-band independent compensation, allowing system R&D engineers to independently adjust parameters for different cable or PCB materials to achieve the best compensation for signal attenuation. In addition, PHISON Electronics provides the exclusive patented Auto Tuning Tool, which can be used with SSD products designed by PHISON to automatically introduce different Redriver gain parameters in the customer's development environment and find the corresponding optimal parameters, accelerating system integration manufacturers. products came to market quickly.

      Furthermore, PHISON Electronics is not only one of the suppliers of high-speed transmission ICs, but also a partner who can assist customers in signal system analysis, simulation and resolution of compatibility issues. Our goal is to provide customers with complete support solutions, solve the technical problems encountered by customers in the development of high-speed interface platforms, and cooperate with the continuous development of new products from CPU chip manufacturers, so that the high-speed interface technology with increasing speed can be used more widely in on every platform.

      PHISON PCIe 5.0 Redriver IC PS7101 passed the strict test of the PCI-SIG Association and became the first PCIe 5.0 Redriver IC in the world to obtain the certification mark of the association, which is an affirmation of the technical strength of PHISON and is of great significance. In addition to PCIe 5.0 Redriver ICs, PHISON is also actively developing a new generation of PCIe 5.0 Retimer ICs (sampling is expected to begin in the first half of 2023) for use in different system environments. Looking forward to the future, PHISON will stick to the IC design industry, create the most reliable and complete high-speed storage and high-speed transmission solutions, and create common prosperity with global customers.

      PHISON's PCIe 5.0 Redriver IC PS7101 has begun to send samples, and has received system design import from many mainstream motherboard, server, industrial computer and cable developers, and mass-produced end-customer products are expected to be launched in 2022/Q3.
