PRODUCT OVERVIEW
2.2 SL240 Features
SL240 provides reliable point-to-point or broadcast interconnects between systems, with
minimal overhead and very low latency. The protocol involved for this transport is based
on Fibre Channel, though it is not Fibre Channel compliant. The major SL240 features
are listed below:
•
Uses proven 8B/10B encoding for data transmission.
•
End-to-end throughput of 247 MBps with or without frame checksums (SL240).
•
Minimizes implementation cost and enhances throughput by using a simple
protocol.
•
Provides built-in data synchronization with very little reduction in throughput.
•
Integrated interrupt controller to report link failure, transaction completion, or
buffer space request.
•
Status LED that reports link stability.
•
Loop operation with out-of-band arbitration or point-to-point operation.
•
Provides a register set designed for easy programming and status retrieval.
•
64-bit operation is backward compatible to 32-bit, 33 MHz.
•
SL240 66 MHz PCI support (3.3 V signaling only) in PMC form factor.
•
128 MB Receive FIFO.
•
1 KB Transmit FIFO.
•
Meets rugged level 2 specifications.
2.2.1 SFF Media Options
There is one SFF media option, short wavelength laser (850nm). The short wavelength
version is useful for intrasystem connections, such as connecting between cards on the
same backplane. It is also suited for short reach intersystem connections (< = 150 m).
All cards use a Duplex LC style connector available from most major cable
manufacturers. For details concerning these connectors, contact
