Variant Link Types

Some of the Sundance link types have variants that can now be used easily.

SDB Links

The link type 'SDB' gives you 32-bit links. Most Sundance modules can support 16-bit SDBs which appear in pairs on the normal 32-bit SDB connectors, and you can access these using the link type 'SDB16'.

These link types overlap: SDB:0 is made up from SDB16:0 and SDB16:1. This means that once you have mentioned SDB:0 in an application you cannot use SDB16:0 or SDB16:1. Similarly, the use

of SDB16:2 precludes the use of SDB:1.

RSL Links

The link type 'RSL' gives you links made up from four lanes working together. You can access single lanes using the link type 'RSL1'.

These link types overlap: RSL:0 is made up from RSL1:0, RSL1:1, RSL1:2, and RSL1:3. This means that once you have mentioned RSL:0 in an application you cannot use any of RSL1:0, RSL1:1, RSL1:2, and RSL1:3. Similarly, the use of RSL1:5 precludes the use of RSL:1.
