The Realtek RTL9210B-CG is a USB (Universal Serial Bus) bridge that combines a USB device with both a PCI Express (PCIe) controller and a SATA controller. Via the PEDET interface of M.2 mechanical, the RTL9210B-CG can auto switch USB-to-PCIe mode, or USB-to-SATA mode.
The RTL9210B-CG supports USB 3.1 GEN2 (Super Speed Plus). It is compatible with USB 3.1 GEN1 (Super Speed), USB High Speed, and Full Speed. It can work normally with auxiliary power. The Mass Storage transaction supports both Bulk Only Transfer (BOT) and USB Attached SCSI Protocol (UASP). For USB, it provides up to 10Gbps bandwidth.
In USB-to-PCIe mode, the RTL9210B-CG supports PCIe Gen3 x2. For PCIe, it provides up to 16Gbps bandwidth. It has full backward compatibility for PCIe Gen2/Gen1 and link width 1 lanes. It supports PCIe 3.0 LTR (Latency Tolerance Reporting). To further reduce power consumption, the RTL9210B-CG supports link power management (PCIe L1. Off and L1. Snooze), PCI MSI (Message Signaled Interrupt) and MSI-X.
In USB-to-PCIe mode, the RTL9210B-CG provides the function of a PCIe host. The PCIe host supports NVM Express, which is an interface that allows a host driver to communicate with an NVMe SSD (Solid-State Disk). The NVMe driver is embedded in customized RAM/Rom/SPI Flash.
In USB-to-SATA mode, the RTL9210B-CG supports SATA host in Gen3 speed. For SATA,
it provides up to 6Gbps bandwidth. It has full backward compatibility for SATA Gen2/Gen1.
In USB-to-SATA mode, the RTL9210B-CG provides the function of a SATA host. The SATA host supports AHCI (Advanced Host Controller Interface) which is an interface that allows a host driver to communicate with a SATA HDD (Hard Disk Drive) or SSD. The AHCI driver is embedded in customized RAM/Rom/SPI Flash.
The RTL9210B-CG supports the Type-C connector. It supports a dynamically switching power state with NVMe/SATA/USB power management for power saving mode. It has an algorithm that can balance power consumption and performance.
The RTL9210B-CG is suitable for multiple market segments and emerging applications, such as desktop, mobile, workstation, server, communications platforms, and embedded applications.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
RTL9210B-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 RTL9210B-CG datasheet above.
Electronic component spot-market pricing for RTL9210B-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 RTL9210B-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.
