M-Link ODIN

-- a G-link based daughter card

compatible with the S-Link connector

DESCRIPTION

The M-Link ODIN is a daughter card with both Agilent G-Link transmitter and receiver chips (3.3V G-Link) and the Infineon Small Form Factor opto-transceiver. The connector is compatible with the S-link mechanical specification and its pinout with the S-link connector's power and ground assignments. This allows a design to use either the M-Link ODIN with S-link cores incorporated into the design's FPGA or to use a standard S-link daughter board. Other, non-S-link, protocols, e.g. raw G-link, can also be used. The card can be populated for simplex or duplex, source or destination. The card uses 3.3V.

The daughter card is narrower than the standard S-link daughter board and so allows up to four M-Link ODINs to be mounted on a 6U VME or compact-PCI mother board. The daughter cards can be cut shorter. The connector-to-front panel distance remains the same.

The M-Link ODIN provides a buffered clock to the motherboard's transmit logic. The link receiver provides the clock recovered from the data stream. The data from the link is presented to the mother board synchronous to this clock.

The M-Link ODIN cards are so far used for prototyping the Front End links into the Muon End cap Trigger chambers (TGCs) RODs (see also the TGC web page) and as an I/O card for the Atlantis reconfigurable processor.
