The IntelliProp IPP-SA111A-BR SATA “Y” Bridge design provides SATA compliant connections and a standard SATA interface to access drive data as well as a direct access port for high speed data storage or retrieval. The SATA host port and the direct access port are selectable via a port select pin. The direct access port, host and device connections are speed independent allowing for speed bridging to the SATA connections.

Functional Description
The hierarchy of the SATA Y-Bridge design can be divided into 3 main blocks:
- SATA Device Port (contains SATA Host Core)
- SATA Host Port (contains a SATA Device Core)
- AMI port and Port Selector
The SATA Device port connects to the storage media. The Y Bridge has an Alternate Media Interface (“AMI”) port that customers use to access (read or write) the drive. Once the switch is activated, all control transfers to the SATA Host Port to allow drive access to the Host PC. This access remains in reset until the customer activates the switch. While this port may become a bottle-neck, it may be used to access the drives in a secondary way.
