Phison Launches the World’s First PCI-SIG Certified PCIe 5.0 Redriver IC to Solve Compatibility Issues in 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-lane transmission speed reaches 32Gbps per second, which is twice that of the previous generation PCIe 4.0. However, in the environment of PCIe 5.0 high-speed transmission, the compatibility issues such as signal attenuation and noise influence on the motherboard have become a common challenge faced by all system integrators.

Phison Electronics recently announced that it has launched the world’s first PCIe 5.0 Redriver IC PS7101 certified by the PCI-SIG Association to help solve the compatibility problem of high-speed signal transmission between CPU and peripheral devices, such as SSD and graphics card.

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 between 2 and 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 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 Flip-Chip packaging and testing technology to reduce signal reflection and crosstalk interference caused by IC packaging. , and at the same time improve IC heat dissipation capability, effectively solve the problem of high-speed transmission signal attenuation of PC and Server platform motherboards or riser cards. It is a high-gain, high-linearity, and cost-effective IC product.

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 provides the exclusive patented Auto Tuning Tool, which can be used with SSD products designed by Phison to automatically bring in different Redriver gain parameters in the customer’s development environment and find the corresponding optimal parameters to speed up the system. The products of the integrated manufacturers go to market quickly.

Pan Jiancheng, CEO of Phison, said that Phison’s PCIe 5.0 Redriver IC PS7101 has passed the strict test of the PCI-SIG Association and has become the first product in the world to receive the Association’s certification mark. This is an affirmation of Phison’s technical strength and is of great significance. In addition to PCIe 5.0 Redriver IC, Phison is also actively developing a new generation of PCIe 5.0 Retimer IC, and it is expected to start sending samples in the first half of 2023 to be suitable for use in different system environments.

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 Q3, 2022. .
