RTL9200-CG

USB 3.1 GEN2 to SATA GEN3 BRIDGE

General Description

The Realtek RTL9200-CG USB (Universal Serial Bus) to SSD (Solid-State Disk) bridge combines a USB device with a SATA bus controller, and embedded memory.

The RTL9200 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 operate normally using 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.

The RTL9200 supports SATA Gen3. For SATA, it provides up to 6Gbps bandwidth. It has full backward compatibility for SATA Gen2/Gen1. To further reduce power consumption, the RTL9200 supports link power management (Partial Mode/Slumber Mode/DEVSLP Mode).

The RTL9200 is suitable for multiple market segments and emerging applications, such as desktop, mobile, workstation, server, communications platforms, and embedded applications.
