Rtl9210b | Datasheet 2021 Verified

Pins dedicated to USB3_TXP/N and USB3_RXP/N require strict 90-ohm differential impedance routing to mitigate EMI and signal degradation at 10 Gbps.

Supports both USB Attached SCSI Protocol (UASP) for high-speed parallel queues and Bulk-Only Transport (BOT) for legacy compatibility. UASP significantly reduces CPU utilization and power overhead.
