PSB 6970 HL V1.3

Telecom Overview

The PSB 6970 HL V1.3 is an L2 seven-port Ethernet switch controller from the XWAY TANTOS family, designed for digital home applications. It features five 10/100Mbit/s ports with TX/FX interfaces and two TMII/MII MAC ports. The device supports a 2K MAC address table and four queues per port for QoS priority handling based on Port-Base, TCP/UDP destination port, DiffServ, 802.1p, IP TOS, and ranged ports. It includes scalable ingress bandwidth control up to 100M, broadcast/multicast storm suppression, and support for packet lengths up to 1536 bytes. The component operates with 1.5V/1.8V/3.3V power sources and utilizes a P/PG-LQFP-100 package.

Telecom Feature Summary

• Provides Layer 2 switching capabilities with advanced QoS features including VLAN tagging, IGMP snooping, and ACLs for traffic prioritization and security.
• Integrates multiple interface types, combining copper and fiber ports with Gigabit MAC interfaces for flexible system integration.
• Includes hardware-based multicast tables and management counters to support efficient video streaming and network monitoring.

Telecom Applications

• ADSL2+, VDSL2, wireless, wire and gateway routers
• IP set-top-box and IPTV systems
• FTTH PON, voice, video, and NAS applications
• HomePlug/HomePNA/MoCA routers

Telecom Procurement Notes

Verify the specific suffix 'HL V1.3' against official Infineon documentation to confirm voltage levels and package variants. Ensure compatibility with required 1.5V, 1.8V, or 3.3V power domains. Confirm that the P/PG-LQFP-100 footprint matches the target PCB design. Check for any RoHS compliance statements in the latest datasheet.

Telecom Selection Notes

Select this controller when a seven-port solution with mixed copper/fiber and Gigabit MAC interfaces is required. Consider the four-queue architecture if strict QoS differentiation for voice, video, and data is necessary. Evaluate the 2K MAC address capacity against expected network size. Verify thermal requirements for the LQFP-100 package in the final enclosure.

Telecom Part Context

This component belongs to the XWAY TANTOS series of high-performance Ethernet switch controllers. It serves as a core switching engine for broadband access devices, replacing discrete switching solutions with a highly integrated single-chip approach. The family includes variants like PSB 6972 and PSB 6973 with different port configurations.

Telecom Replacement Considerations

Direct replacements within the same family include PSB 6972 (with RGMII/GMII/TMII/MII ports) and PSB 6973 (in LFBGA-225 package). Verify pinout compatibility and software register mapping before substitution. Cross-referencing tools should be used to identify equivalent third-party components if needed.
