The Realtek RTL9211DS-CG USB (Universal Serial Bus) to SD Express interfaces and SSD (Solid-State Disk) bridge combines a USB device with a PCI Express bus controller and embedded memory.
The RTL9211DS supports USB 3.2 Gen2x1 (Super Speed Plus). It is compatible with USB 3.2 Gen1x1 (Super Speed), USB High Speed, and Full Speed. It can also operate using auxiliary power. Mass storage transactions support both Bulk Only Transfer (BOT) and USB Attached SCSI Protocol (UASP). For USB, it provides up to 10Gbps bandwidth. When the RTL9211DS is connected with an SD Express card, the SD Express port can reach a data transmission speed of 985MB/s. Additionally, the RTL9211DS supports the highest theoretical capacity specification of the 128TB SD card.
The RTL9211DS supports PCIe Gen3x2. For PCIe, it provides up to 16Gbps bandwidth. It has full backward compatibility for PCIe Gen2/Gen1 and 1 lane link width. It supports PCIe 3.0 LTR (Latency Tolerance Reporting). To further reduce power consumption, the RTL9211DS supports link power management (PCIe L1.off and L1.Snooze), PCI MSI (Message Signaled Interrupt) and MSI-X.
The RTL9211DS provides the function of PCIe host. The PCIe host supports NVM Express, which is an interface that allows the host driver to communicate with SSD. The NVMe driver is embedded in customized RAM/Rom/SPI Flash.
The RTL9211DS supports the Type-C connector. It supports dynamically switching power states with NVMe and USB power management for power saving mode. A built-in algorithm balances power consumption and performance.
The RTL9211DS is suitable for multiple market segments and emerging applications, including desktop, mobile, workstation, server, communications platforms, and embedded applications.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
RTL9211DS-CG is an authentic electronic component manufactured by Realtek, categorized under Interface ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official RTL9211DS-CG datasheet above.
Electronic component spot-market pricing for RTL9211DS-CG fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for RTL9211DS-CG depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
