Product details
Overview
PSF 6973 EL V1.3-G from Infineon Technologies is a Layer 2 seven-port 10/100 Mbit/s Ethernet switch controller with four RGMII/GMII/TMII/MII MAC interfaces and three 10/100 TX/FX PHY ports, supporting up to 16 VLAN groups, hardware IGMP v1/v2/v3/MLD v1/v2, and per-port bandwidth control in 64 kbps steps up to 100 Mbps - deployed in FTTH PON gateways and IP set-top boxes.
For engineers reviewing the PSF 6973 EL V1.3-G datasheet, PSF 6973 EL V1.3-G pinout, PSF 6973 EL V1.3-G application, or PSF 6973 EL V1.3-G equivalent, key selection criteria include RGMII interface count, VLAN group scalability, IGMP hardware table depth (32 entries), QoS queue arbitration mode (WRR + strict), and LFBGA-225 package compatibility with high-density routing.
Technical Context
The PSF 6973 EL V1.3-G implements a fully integrated switch engine with pointer memory, buffer management, and queue arbiter supporting four priority queues per port using Weighted Round Robin and strict priority scheduling. It processes packets up to 1536 bytes and enforces ingress bandwidth control per port with 64 kbps granularity.
Its switching logic supports IEEE 802.1Q VLAN tagging (Tag/Untag), 802.1p and DiffServ-based QoS classification, ACL filtering on MAC/EtherType/IP/TCP/UDP fields, and hardware-accelerated IGMP join/leave with fast leave response - all managed via MDC/MDIO or PCI host interface.

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-B1-NNC1I | 6-port 10/100 switch with MII-only MAC interfaces; no RGMII/GMII; 1K MAC table vs. 2K | Lacks hardware IGMPv3/MLDv2 acceleration and VLAN group scalability beyond 8 groups | Preferred where cost-sensitive designs omit triple-play multicast features and use legacy MII PHYs |
| Realtek RTL8367RB | 7-port 10/100 switch with embedded 5-port PHY; single 3.3 V supply; no TMII/RGMII flexibility | Integrated PHY eliminates external magnetics but restricts interface choice and limits GMII bandwidth to 200 Mbps | Selected when board space is constrained and RGMII/GMII interface flexibility is not required |
Compared with Marvell 88E6097-B1-NNC1I and Realtek RTL8367RB, PSF 6973 EL V1.3-G uniquely delivers RGMII/GMII/TMII interface versatility, 32-entry hardware IGMP table, and 16-VLAN group support - critical for carrier-grade FTTH and IPTV platforms requiring scalable multicast and strict QoS enforcement.

FAQ
What voltage supplies does PSF 6973 EL V1.3-G require?
The PSF 6973 EL V1.3-G operates from three independent supply rails: 1.5 V core, 1.8 V I/O, and 3.3 V analog/PHY - each with dedicated power pins and decoupling requirements specified in the Infineon XWAY TANTOS Hardware Design Guide Rev. 1.3.
Does PSF 6973 EL V1.3-G support IEEE 1588 Precision Time Protocol?
No, PSF 6973 EL V1.3-G does not implement IEEE 1588 PTP timestamping or hardware time synchronization features. Its timing capabilities are limited to standard Ethernet frame forwarding, MDC/MDIO clocking, and internal scheduler clocks derived from REFCLK.
Can PSF 6973 EL V1.3-G be used without an external flash memory?
Yes - the device supports boot-from-ROM mode using internal mask ROM for basic initialization, though full feature enablement (VLAN, QoS, IGMP) requires configuration via external SPI flash or host CPU register writes during startup.
Is there hardware support for IPv6 multicast in PSF 6973 EL V1.3-G?
Yes - the device implements full IPv6 Multicast Listener Discovery (MLD) v1 and v2 in hardware, including 32-entry MLD table with fast-leave processing and snooping on all seven ports, as documented in the XWAY TANTOS Software Programmer's Manual Section 4.7.
