This section describes the high-density I/O (HDIO) banks. The HDIO bank HDA (bank 45) is accessible through the SOM240_1 connector. HDIO banks HDB (bank 43) and HDC (bank 44) are accessible through the SOM240_2 connector.
- The HDA bank supports 21 single-ended signals HDA[20:0]. Three signals (HDA00_CC, HDA08_CC, and HDA16_CC) are clock-capable inputs available on the MPSoC.
- The HDB and HDC bank supports 24 single-ended signals HDx[23:0]. Three signals (HDx00_CC, HDx08_CC, and HDx16_CC) are clock-capable inputs available on the MPSoC.
- The maximum data rate supported on HDIO signals is 250 Mb/s.
- VCCO for the HD(x) bank is supplied by the carrier card through the VCCO_HD(x) pins where x = A, B, or C.
HDIO bank connections are listed in the following table.
