5.1.4
SATA
The conga-TC570r offers two SATA interfaces (SATA 0-1) on the A–B connector. The interfaces support:
•
independent DMA operation
•
data transfer rates up to 6.0 Gb/s
•
AHCI mode using memory space and RAID mode
•
Hot-plug detect
Note
1. SATA0 is multiplexed with PCIe6 while SATA1 is multiplexed with PCIe5.
2. The interface does not support legacy mode using I/O space.
5.1.5
USB
The conga-TC570r offers eight USB 2.0 interfaces on the A–B connector and up to four SuperSpeed signals on the C–D connector. The xHCI
host controller supports:
•
USB 3.2 specification
•
SuperSpeedPlus, SuperSpeed, High-Speed, Full-Speed and Low-Speed USB signaling
•
data transfers of up to 10 Gbps for USB 3.2 Gen 2x1 port
•
data transfers of up to 5 Gbps for USB 3.2 Gen 1x1 port
•
supports USB debug port on all USB 3.2 capable ports
Note
1. The USB 3.2 Gen 2x1, port 3 is multiplexed with PCIe7. For PCIe lane 7, a custom BIOS is required.
2. The USB ports are configured in the BIOS setup menu to operate by default in Gen 1 mode. Before you change the default setting to
Gen 2, ensure the carrier board supports Gen 2 operation. For Gen 2 design considerations, contact congatec technical support center.
Caution
To pass the Electrical Fast Transient (EFT) test, you must add a schottky diode (1SS402 or equivalent) to all USB 2.0 data lanes routed to a
connector on your carrier board.
