According to the device specifications, the RTL9210B supports the standard, offering a maximum theoretical bandwidth of 20 Gbps . On the host side, it utilizes a PCIe Gen 3 x2 interface. While the chip is capable of supporting PCIe Gen 3 x4 speeds, the upstream USB 20 Gbps limit renders a x4 interface redundant for throughput, making the x2 configuration the optimal design choice for manufacturers to reduce PCB trace complexity.
This guide is intended for engineers, DIY enthusiasts, and hardware integrators looking to use the RTL9210B in NVMe enclosure designs. rtl9210b datasheet
The RTL9210B features an integrated DC-DC controller. This reduces the Bill of Materials (BOM) cost for manufacturers because fewer external voltage regulation components are needed on the PCB. This guide is intended for engineers, DIY enthusiasts,
