USB 3.0 SSIC Adapter

Arasan Superspeed Inter-chip Controller (USB 3.0 SSIC Adapter) uses Arasan’s MIPI-M-PHY (Type-1) v. 3.0 to implement the SSIC adaptation to the USB3 PIPE interface. The Arasan USB 3.0 SSIC adapter is compliant with the “Inter-Chip supplement to the USB revision 3.0 specification, version 1.0” and the MIPI-M-PHY specification revision 3.0-r.03 and provides an effective data rate of up to 5.0 Gbps per lane, over 1 to 4 lanes of M-PHY. The USB 3.0 SSIC Adapter IP interfaces to the USB3 Device/Host controller with PIPE3 interface at 8/16/32-bit data width.

Leveraging the MIPI-M-PHY power management, SSIC adapter lowers the active power and idle power. The USB 3.0 SSIC adapter is optimized for power, area, and EMI robustness for embedded inter-chip interfaces.

The USB 3.0 SSIC Adapter is delivered as digital RTL.
