Switch Fabric Data Sheet 89TSF552 Preliminary Information*
89TSF552 (queuing engine, 10 Gbps).
89TSF500 (crossbar and scheduler).
The 89TSF552 typically resides on a line card and the 89TSF500 usually resides on a separate switch card. An 89TSF552 connects with the 89TSF500 through high-speed serial links.
The 89TSF5xx switch fabric has a modular and scalable architecture that gives system designers maximum flexibility and performance. This architecture allows a switch to be implemented either on a single shelf using an electrical backplane or on multiple shelves connected by optical transceivers, thus helping system vendors overcome physical space constraints.
The 89TSF552 supports line card speeds up to OC-192 (full duplex). It incorporates a 16-bit CSIX-over-LVDS interface to line card devices, allowing the 89TSF5xx to operate seamlessly with the IDT 89TTM552 traffic manager, or other compatible traffic managers and network processors.
In the ingress direction, the 89TSF552 manages a set of virtual output queues (VOQs), negotiates the routing path through the switch fabric, and transmits data to an 89TSF500. In the egress direction, the 89TSF552 receives data from an 89TSF500 and transmits the traffic, through a CSIX-over-LVDS interface, either to IDT’s 89TTM552 traffic manager or to another device (such as a network processor) on the line card.
