The VSC7130 is used in Fibre Channel (1.0625Gb/s) and Gigabit Ethernet (1.25Gb/s) systems to provide bidirectional Clock and Data Recovery (CDR) to ensure standards compliance at critical systems interfaces. As protocol ASICs integrate multiple SerDes functions, the ASICs tend to be located far from interface connectors which results in signal degradation and difficulty in meeting industry-standard signal quality specifications. The VSC7130 provides a low-cost, easy-to-use solution to this problem by ensuring standards-compliant signal quality at system interfaces. Additional circuitry implements an FC-AL Hub node. The VSC7130 provides a pair of bidirectional CDRs which can be configured as either repeaters or retimers or bypassed altogether. Internal system data is recovered and retransmitted with standards-compliant signal quality at the connector. External receive data from the connector is recovered and retransmitted to the internal system with increased amplitude and attenuated jitter. An optional Two-Wire Interface allows robust configuration control and status monitoring of the device in order to enhance operation.
