VSC8228
Dual Channel Multirate Signal Conditioner and Retimer
BENEFITS:
4Provides
Fibre Channel and Gigabit Ethernet Signal Conditioning, Improving
the Signal Integrity
4Offers
flexible implementation. FibreTimer in Retimer Mode Minimizes the
Jitter Generation, While Maintaining High Jitter Tolerance. In Repeater
Mode Offers Low Latency Signal Cleanup. Bypass Mode Allows Support
for Rates in not Directly by the CDR.
4Supports
Exteneded Trace Lengths Over Copper Backplanes and Cables,
Ideal for Backplane and Rack-to-rack Applications
4Supports
enhanced receiver diagnostic capabilities.
