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
FEATURES:
4Dual Clock and Data Recovery Architecture for Gigabit
Ethernet and Fibre Channel Applications
4FibreTimer™ Configurable Clock Recovery Unit (CRU):
Repeater, Retimer, or Bypassed
4Programmable Input Signal Equalization, Output
De-emphasis, and Output Drive Levels
4Analog Signal Detect and Protocol Monitor Indicators
4Optional Half-rate SGMII Clock and Repeated Reference
Clock Output
4Built In Self Test Which can Generate and Detect an
Unframed 2^7, 2^23, and 2^31 Pseudorandom Bit
Stream (PRBS), a User Defined Pattern, and the Fibre
Channel CRPAT, CJTPAT, and CSPAT Patterns
4Supports enhanced receiver diagnostic capabilities.
4Provides SerDes to SGMII Gigabit Ethernet interface conversion.
4Enables Comprehensive System Diagnostic Capabilities. The Extended
Pattern Support Reduces the Need for External test Equipment
