Example 1: Fibre Channel Protocol Application

Example 1: Fibre Channel Protocol Application
Assume that you want to implement a fibre channel protocol application using three
transceiver channels. Consider the following system requirements:
■ You need three transceiver channels
■ All the channels need to be placed in the same transceiver block
All the channels need to have independent control to reset their PCS and PMA
■

Phase 1—Architecture
In this phase, check whether the Stratix IV GX device supports or meets your design
requirements.

Device Specification

Consider the questions listed in
Table 2–3. Device Specific Parameters
Questions
Do the parameters meet the fibre channel protocol
electrical requirements?
Are three transceiver channels available?
Is there support for 4.25 Gbps and 1.0625 Gbps data
rates?
f
For the maximum data rates supported, refer to the "Transceiver Performance
Specifications" section in the
chapter.

Yes
Two CMU PLLs are available within each transceiver block to
support two different transmitter data rates. Each receiver
channel contains a dedicated receiver CDR that supports
4.25 Gbps and 1.0625 Gbps data rates.
