2.1.1.1. Possible Combinations of GX and GXT Channels in H-Tile
Note: Refer to protocol specification for IL. For example, for 28G, Backplane support is CEI 3.0 25GLR. Different rates are supported by different specifications.
Channel Type | Number of Channels per Bank | Channel Capability for H-Tile | |
---|---|---|---|
Chip-to-Chip & Chip-to-Module | Backplane | ||
GX | 2 | 12.5 Gbps | N/A |
GXT 3 | 4 | 28.3 Gbps | 28.3 Gbps |
