Product details

Overview

PSB 6972 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 RGMII/GMII/TMII/MII MAC ports, integrated 2K MAC address table, hardware IGMP v1/v2/v3/MLD support, and per-port bandwidth control (64 Kbps step, up to 100 Mbps). It enables QoS-aware multimedia routing in ADSL2+/VDSL2 gateways and IPTV set-top boxes.

For engineers reviewing the PSB 6972 HL V1.3 datasheet, PSB 6972 HL V1.3 pinout, PSB 6972 HL V1.3 application, or PSB 6972 HL V1.3 equivalent, key selection criteria include RGMII interface compatibility, VLAN group count (16), IGMP hardware table size (32 entries), 802.1x security support, and LQFP-100 package thermal and layout constraints.

Technical Context

The PSB 6972 HL V1.3 implements a fully integrated switch engine with seven independent port data paths, supporting simultaneous ingress/egress at line rate across all ports. Its queue arbitration combines Weighted Round Robin and strict priority modes, enabling differentiated treatment of voice (low-latency), video (bandwidth-guaranteed), and data (best-effort) traffic streams.

It embeds dedicated hardware accelerators for 802.1Q VLAN tagging/untagging, ACL filtering on MAC/EtherType/IP/TCP/UDP fields, and RMON counters per port. Management is performed via MDIO/MDC or PCI host interface, with full register-level access to buffer management, pointer memory, and scheduling logic.

Key Specifications

Parameter	Value and Actual Design Meaning
Port Count & Type	7 total: 5× 10/100 TX/FX PHY + 2× RGMII/GMII/TMII/MII MAC - enables mixed PHY/MAC topology for WAN/LAN separation
MAC Address Table	2,048 entries - sufficient for medium-scale residential gateway with multiple VLANs and connected devices
VLAN Support	Up to 16 groups using full 12-bit VLAN ID - supports service provider segmentation and multi-tenant isolation
IGMP/MLD Hardware Table	32-entry multicast table with HW join/fast leave - reduces CPU load in IPTV multicast streaming
Per-Port Bandwidth Control	Adjustable in 64 Kbps steps up to 100 Mbps - allows precise SLA enforcement per subscriber port
QoS Queues per Port	4 configurable queues with WRR/strict priority - enables three-tier traffic shaping (voice/video/data)

Pinout & Package

PSB 6972 HL V1.3 is housed in a P/PG-LQFP-100 package (14 mm × 14 mm, 0.5 mm pitch), with 1.5 V/1.8 V core and 3.3 V I/O supply domains. Thermal pad exposed on underside requires PCB thermal via array for reliable operation at full packet throughput.

Pin/Terminal	Circuit Role	Design Meaning
MDC / MDIO	Management Data Clock / Input-Output	Serial interface to external PHYs or configuration EEPROM; supports IEEE 802.3 clause 22/45 register access
RGMII_TXCK / RXCK	RGMII Transmit/Receive Clock	Source-synchronous 125 MHz clocks for 1 Gbps aggregate RGMII link; requires matched trace length to MAC
REFCLK	Reference Clock Input	25 MHz crystal or oscillator input for internal PLL; critical for timing accuracy of all MAC/PHY blocks
RESET_N	Active-Low Asynchronous Reset	Resets all internal state machines and registers; must be held low ≥100 µs after power stabilization
PCI_AD[31:0]	PCI Address/Data Multiplexed Bus	32-bit multiplexed address/data interface for host CPU connection; supports PCI 2.3 33 MHz operation

Key Features

Feature	Design Value
Hardware IGMP Snooping v1/v2/v3 & MLD v1/v2	32-entry multicast table with zero-CPU join/leave latency - eliminates flooding in IPTV deployments
Programmable Per-Port Storm Suppression	Configurable broadcast/multicast rate limit per port - prevents network collapse during topology changes
ACL Engine	Filter on MAC SA/DA, EtherType, IP protocol, TCP/UDP port ranges - enforces firewall-like policies at line rate
802.1x Port-Based Authentication	IEEE 802.1x EAP frame handling in hardware - offloads authentication processing from host CPU
PCI Host Interface	32-bit 33 MHz PCI 2.3 compliant bus - enables direct integration with MIPS/x86 SoCs without bridge logic

Applications

Use Value: Delivers enterprise-class visibility (per-port byte/packet counters, error stats) in cost-sensitive residential hardware.

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	6-port 10/100 switch with MII-only MAC interfaces; no RGMII; smaller 1K MAC table	Lacks RGMII support and hardware IGMPv3/MLD - unsuitable for IPTV multicast scaling	Select only if RGMII is not required and IGMPv2 suffices for basic multicast
Realtek RTL8367RB	7-port 10/100 switch with embedded PHYs; single 3.3 V supply; no PCI interface	Integrated PHYs reduce BOM but eliminate flexibility for external GMII/RGMII PHY selection	Prefer when PHY integration is acceptable and host interface is SPI/MDIO-only

Compared with Marvell 88E6097 and Realtek RTL8367RB, PSB 6972 HL V1.3 uniquely combines RGMII MAC ports, hardware IGMPv3/MLD, and PCI host interface - making it optimal for SoC-based residential gateways needing scalable multicast and CPU offload.

FAQ

Does PSB 6972 HL V1.3 support Gigabit Ethernet?

No. PSB 6972 HL V1.3 supports only 10/100 Mbit/s per port. Its two RGMII interfaces operate at 100 Mbps each (200 Mbps aggregate), not 1 Gbps. The "RGMII" label refers to the interface standard, not speed - actual data rate is limited by internal MAC design to 100BASE-TX.

What is the maximum operating junction temperature for PSB 6972 HL V1.3?

The PSB 6972 HL V1.3 is rated for industrial temperature operation from –40 °C to +85 °C ambient. With proper PCB thermal vias under the exposed pad and 2-layer copper pour, junction temperature remains within safe limits (<125 °C) at full 7-port line-rate traffic.

Can PSB 6972 HL V1.3 operate without an external crystal?

No. PSB 6972 HL V1.3 requires a 25 MHz fundamental-mode crystal connected to REFCLK pins for internal PLL clock generation. An external oscillator may substitute only if it meets jitter (<100 ps RMS) and slew rate specifications defined in Infineon's XWAY TANTOS Hardware Design Guide.

Is PCI interface mandatory for configuration and operation?

No. While PCI provides full register access and DMA capability, PSB 6972 HL V1.3 also supports configuration via MDIO/MDC interface to an external PHY or microcontroller. However, PCI is required for high-throughput packet forwarding in host-controlled mode.
