Optical Dual G-LINK (ODIN) S-LINK Interface

LSC/LDC-D-40-B-5.0/3.3-160

Link Destination Card in double G-LINK configuration (other side, large)
(Circuit number 680-1110-950)

DESCRIPTION

The ODIN S-LINK interface is a standard S-LINK implementation, which uses in the full configuration two 3.3 V Hewlett Packard G-LINKs (HDMP-1032/1034) as a physical layer for the forward channel. The same chip is used for the return channel. For the optical transmission small form-factor (SFF) optical transceivers with duplex LC connectors are used.

The design is not intented to be used in an environment with radiation. ODIN cards are commercially available from the company CERNTECH and are also available from the CERN stores.

ODIN cards are available in a full-speed version using two duplex LC cables and a cheaper, lower-speed version that uses a single duplex LC cable. All types are available in 5 Volt and 3.3 Volt versions.
