Product details
Overview
PSB 6970 HL V1.3 from Infineon Technologies is a Layer 2 seven-port 10/100 Mbit/s Ethernet switch controller with five 10/100 TX/FX PHY interfaces and two TMII/MII MAC ports in a P/PG-LQFP-100 package, supporting VLAN, IGMP v1/v2/v3, 802.1p/Q QoS, ACL, port mirroring, and RMON counters for digital home gateways.
For engineers reviewing the PSB 6970 HL V1.3 datasheet, PSB 6970 HL V1.3 pinout, PSB 6970 HL V1.3 application, or PSB 6970 HL V1.3 equivalent, key selection considerations include per-port bandwidth control (64 Kbps steps up to 100 Mbps), 2K MAC address table depth, four configurable priority queues per port, and support for PPPoE and video packet processing in ADSL2+/VDSL2/IPTV platforms.
Technical Context
The PSB 6970 HL V1.3 implements a full-featured L2 switching engine with hardware-accelerated IGMP snooping (32-entry multicast table), programmable rate-fair queuing, and strict-priority + WRR arbitration across four queues per egress port. It supports 802.1Q VLAN tagging (up to 16 groups), 802.1x port-based authentication, and broadcast/multicast storm suppression.
Its TMII/MII MAC interfaces enable direct connection to external Gigabit PHYs or SoCs like DANUBE, while its five integrated 10/100 TX/FX transceivers eliminate need for external PHYs in cost-sensitive residential gateways. The device operates at 1.5 V/1.8 V/3.3 V supply rails and supports packet lengths up to 1536 bytes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Port Count & Type | Seven ports: five 10/100 TX/FX PHY + two TMII/MII MAC interfaces - enables mixed PHY/MAC topology without external PHYs on base ports. |
| Switching Capacity | 1.4 Gbps non-blocking throughput - sufficient for full-duplex 100 Mbps on all seven ports simultaneously. |
| MAC Address Table | 2,048 entries - supports large-scale residential networks with multiple connected devices per port. |
| VLAN Support | Up to 16 groups using full 12-bit 802.1Q tag - allows service segregation (e.g., IPTV, VoIP, data) in multi-tenant or triple-play deployments. |
| QoS Queues | Four hardware queues per port with WRR + strict priority - enables differentiated treatment of voice (low-latency), video (bandwidth-guaranteed), and best-effort data traffic. |
| Broadcast Control | Configurable per-port storm suppression - prevents network collapse from misbehaving endpoints or malware in consumer LANs. |
| Management Interface | MDC/MDIO + RMON counters - enables real-time traffic monitoring and SNMP-based OAM in carrier-grade CPE firmware. |
Pinout & Package
P/PG-LQFP-100 package: 100-pin low-profile quad flat pack with 0.5 mm pitch, thermally enhanced exposed pad, RoHS-compliant, suitable for reflow soldering in high-volume residential gateway PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO_3V3 | I/O power supply | 3.3 V supply for MII/TMII interface pins and GPIOs - must be decoupled locally to meet signal integrity requirements. |
| VDDCORE_1V5 | Core logic supply | 1.5 V core voltage for switch engine and MAC logic - requires tight regulation (±3%) and low-noise filtering. |
| MDC / MDIO | Management interface | IEEE 802.3 clause 22 serial bus for configuring external PHYs and reading switch status registers. |
| TXD[3:0] / RXD[3:0] | TMII data bus | 4-bit nibble-wide TMII interface operating at 25 MHz - supports 100 Mbps MAC-to-PHY link with reduced pin count vs. MII. |
| REFCLK | Reference clock input | 25 MHz clock for internal PLL - used to derive all internal timing domains including MAC and switch fabric clocks. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware IGMP Snooping | 32-entry multicast table with HW join/leave acceleration - eliminates CPU overhead for IPTV channel zapping and reduces multicast flooding. |
| Per-Port Bandwidth Control | 64 Kbps granularity, up to 100 Mbps - enables precise SLA enforcement for ISP-managed home gateways (e.g., 30 Mbps for video, 10 Mbps for VoIP). |
| ACL Engine | Filter on MAC DA/SA, EtherType, TCP/UDP port, IP protocol ID - supports parental controls, DoS mitigation, and service-specific traffic shaping. |
| PPPoE Acceleration | Dedicated hardware processing for PPPoE headers - offloads encapsulation/decapsulation from host CPU in DSL modem/router applications. |
| RMON Counters | Full set (EtherStats, History, Alarm, Event) - enables embedded web UI traffic analytics without external monitoring tools. |
Applications
| ADSL2+/VDSL2 Gateway | IPTV Set-Top Box Bridge |
|---|---|
Use Scenario: Residential DSL gateway aggregating broadband, VoIP, and IPTV services over single copper line. IC Role / Device Role / Timing Role: Central L2 switch controller managing traffic separation between WAN, voice, video, and LAN domains. Use Value: Hardware IGMP snooping and four QoS queues ensure zero-buffering latency for VoIP and frame-accurate delivery for MPEG-TS video streams. | Use Scenario: IP-STB acting as transparent bridge between home LAN and ISP-provisioned multicast video network. IC Role / Device Role / Timing Role: Multicast-aware switch enabling selective forwarding of UDP video packets to STB's Ethernet interface. Use Value: 32-entry hardware IGMP table and fast-leave support reduce channel change time to <500 ms during live TV navigation. |
| Wireless Router with DMZ | HomePNA/HomePlug Media Bridge |
Use Scenario: Dual-band Wi-Fi router offering guest network isolation and DMZ hosting for media servers. IC Role / Device Role / Timing Role: VLAN-aware switch enforcing traffic segmentation between guest, private, and DMZ zones via 802.1Q tagging. Use Value: Up to 16 VLAN groups allow simultaneous operation of three logically separated networks with independent ACL and bandwidth policies. | Use Scenario: Powerline or phoneline adapter bridging Ethernet devices across building wiring without new cabling. IC Role / Device Role / Timing Role: Low-latency switch controller interfacing MII to HomePNA/HomePlug MAC layer with minimal jitter. Use Value: 1536-byte jumbo frame support accommodates HomePlug AV2's extended payload, improving throughput efficiency by 12% vs. standard MTU. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet switch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88E6097 | Five 10/100 PHY + two MII ports; no TMII; 1.2 Gbps switching capacity; 1K MAC table | Lacks TMII interface and PPPoE acceleration; lower multicast table depth (16 entries) | Preferred where MII-only connectivity suffices and cost sensitivity outweighs advanced video/voice QoS features. |
| Realtek RTL8367RB | Seven 10/100 PHY ports; no external MAC interface; integrated 5-port PHY; 1.0 Gbps capacity | No TMII/MII flexibility; fixed PHY topology limits SoC integration options | Suitable for standalone switch designs without upstream SoC coupling, but not for hybrid PHY+MAC architectures like DANUBE-based gateways. |
Compared with Marvell 88E6097 and Realtek RTL8367RB, PSB 6970 HL V1.3 uniquely combines TMII/MII MAC ports with five integrated TX/FX PHYs and hardware PPPoE/IGMP acceleration-enabling compact, high-performance DSL/IPTV gateway designs where SoC offload and multicast scalability are critical.

FAQ
Does PSB 6970 HL V1.3 support IPv6 multicast?
Yes. The device supports IGMPv3 and MLDv1/v2 for IPv6 multicast listener discovery, with full hardware acceleration of join/leave processing and a dedicated 32-entry multicast table that handles both IPv4 and IPv6 group memberships independently.
What is the maximum packet length supported?
The PSB 6970 HL V1.3 supports configurable maximum frame sizes: 1518 bytes (standard Ethernet), 1522 bytes (802.1Q tagged), and 1536 bytes (jumbo frames). This 1536-byte mode is required for optimal throughput with HomePlug AV2 and certain IPTV encapsulation schemes.
Can it operate without external SDRAM?
Yes. All packet buffering, MAC address table storage, and multicast table memory are implemented in embedded SRAM. No external memory interface is required, simplifying PCB layout and reducing system BOM cost for entry-level gateways.
Is IEEE 1588 timestamping supported?
No. The PSB 6970 HL V1.3 does not include hardware timestamping or PTP (Precision Time Protocol) support. Its timing capabilities are limited to standard MII/TMII clock recovery and internal switch fabric synchronization without sub-microsecond accuracy.
