VSC7556-V/5CC

Telecom Overview

The VSC7556-V/5CC is a SparX-5 Enterprise Ethernet switch IC supporting up to 160 Gbps of non-blocking bandwidth. It features a maximum of 64 ports, including configurations such as 16x10G or 10x10G plus 2x25G. The device integrates 32 Mb of shared packet memory and supports Layer 2/Layer 3 forwarding with IPv4/IPv6 routing capabilities. A dual-core 1 GHz ARM Cortex-A53 CPU manages the switch functions.

Telecom Feature Summary

• Supports advanced TCAM-based VLAN and QoS processing for differentiated services
• Integrates Versatile Content-Aware Processor (VCAP) for security and frame processing
• Provides flexible port configurations with 25G aggregation link support
• Includes Energy Efficient Ethernet (EEE) and Priority-Based Flow Control (PFC)

Telecom Applications

• Enterprise L2 managed and L2/L3 managed equipment
• WiFi aggregation points
• Base stations and baseband processor interconnect
• Service provider CPEs

Telecom Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with required DDR3/DDR4 external memory interfaces and PCIe connections for system integration.

Telecom Selection Notes

Select this model when 160 Gbps switching capacity is required. Compare against VSC7552 for lower bandwidth needs or VSC7558 for higher throughput. Confirm that the integrated 32 Mb buffer meets the latency requirements for the target application.

Telecom Part Context

This component belongs to the SparX-5 family of L2/L3 Enterprise switches. It shares the same core architecture and CPU subsystem with the VSC7552 and VSC7558 models, differing primarily in port count and aggregate switching bandwidth specifications.

Telecom Replacement Considerations

VSC7552TSN-V/5CC and VSC7558-V/5CC are part numbers within the same SparX-5 family offering different bandwidth tiers.
