The PSDB line cards provide the flexibility to complete the GiDEL PROCSpark II / PROCStar II system with additional connectivity and functionality. System connectivity is achieved on these daughterboards via 1.6GHz connectors, providing more connection speed.

There are several options for the user to fit a daughterboard to his/her needs, no matter which kind of PROC motherboard he/she has chosen:

• Using one of the existing GiDEL's daughter boards
• Creating a daughterboard basing on a GiDEL PSDB_Proto daughterboard
• Developing a custom daughter board, or
• Using GiDEL's outsourcing in order to develop a daughter board according to the user's requirements.

General Features:

• Clocking: PROC motherboard's main clocks as well as dedicated clock outputs enter the daughter boards.
• Power supply: PROC motherboards supply 5V, 3.3V, 2.5V and 1.8V to the daughterboards.
• Connectivity: The PSDB cards connect to the PROC motherboard via one or two 1.6GHz connectors.
• Identification: PROC motherboards identify the installed daughterboard(s) and notify the host software of their presence.
