| 12 | +description: |
| 13 | + The TI PIPE3 PHY is a high-speed SerDes (Serializer/Deserializer) |
| 14 | + transceiver integrated in OMAP5, DRA7xx/AM57xx, and similar SoCs. |
| 15 | + It supports multiple protocols (USB3, SATA, PCIe) using the PIPE3 |
| 16 | + interface standard, which defines a common physical layer for |
| 17 | + high-speed serial interfaces. |
