This section describes the high-performance I/O (HPIO) banks. The HPIO bank HPA (bank 65, bank 66) is accessible through both the SOM240_1 and SOM40 connectors.
- Most signals in the HPIO banks are routed as differential pairs. The HPIO bank has a separate differential global clock input, namely HPA_CLK0_P/N.
- The maximum data rate supported on HPIO signals is 2.5 Gb/s.
- VCCO for the HPA bank is supplied by the carrier card through the VCCO_HPA pins.
HPIO bank connections are listed in the following table.
| HPIO Bank | Connector | HPIO Signals | Clock-capable Pins | VCCO |
|---|---|---|---|---|
| HPA bank 65, HPA bank 66 | SOM240_1 | HPA[24:00]_P/N, HPA[25:28], HPA_CLK0_P/N | HPA_CLK0_P/N | VCCO_HPA |
