Concept: Taiwanese electronics company Phison has deployed the world’s first PCIe (Peripheral Component Interconnect Express) 5.0 Redriver IC (integrated circuit) PS7101 certified by the PCI-SIG (Peripheral Component Interconnect Special Interest Group) Association. It aims to assist in solving the high-speed signal transmission compatibility issues between the CPU (Central Processing Unit) and peripheral devices such as SSDs (solid-state drive) and graphics cards.

Nature of Disruption: The PS7101 PCIe 5.0 Redriver IC uses Flip-Chip packaging and testing technologies to eliminate signal reflection and crosstalk interference caused by IC packaging while also increasing the IC’s heat dissipation capability. It claims to solve the problem of high-speed signal attenuation between the PC motherboard and the server platform or riser card. According to the manufacturer, PS7101 is a high-gain, high-linearity, and cost-effective IC. The product features multi-band independent compensation, which allows system R&D experts to modify parameters independently for different cable or PCB (printed circuit board) materials. Additionally, Phison offers the patented Auto Tuning Tool, which are compatible with Phison SSD products. This automatically imports various Redriver gain settings into the customer’s development environment and identifies the ideal parameters, enabling system integrators to get their solutions to market faster.

Outlook: The demand for high-speed data transmission is growing in tandem with the rapid development of large datasets, AI, and cloud computing. The CPU is at the heart of high-speed signal transmission. Compatibility difficulties such as signal attenuation and noise impacts on the motherboard have become regular problems and challenges for all system integrators in the high-speed transmission environment of PCIe 5.0. The PCIe 5.0 Redriver IC PS7101 aims to address high-speed transmission compatibility issues imposed by the PCIe 5.0. Phison intends to introduce mass-produced products for end consumers in the third quarter of 2022.
