Add To BomRTL8309SC General Description
General DescriptionThe RTL8309SB is a 128-pin, ultra low power, high-performance 8-port Fast Ethernet single-chip switch with one extra MII port for specific applications. It integrates all the functions of a high speed switch system—including SRAM for packet buffering, non-blocking switch fabric, address management, one general use MII interface, eight 10/100Base-TX transceivers, and nine Media Access Controllers—into a single 0.18µm CMOS device. It provides compatibility with all industry standard Ethernet and Fast Ethernet devices. Only a 25MHz crystal is required; the EEPROM is optional to save BOM costs.Features■ Integrates eight 10/100 transceivers and nine MAC units for 10Base-T and 100Base-TX.■ Embedded SRAM for packet storage.■ On-chip 1024-entry look-up table in direct mapping mode.■ Embedded 16-entry CAM for hash collision mapping.■ Provides read/write access to look-up table entries via SMI interface.■ Provides non-blocking wire speed reception and transmission.■ Flow control fully supported: ◆ Half-duplex: backpressure flow control. ◆ Full-duplex: IEEE 802.3x flow control.■ Support for 4 LEDs per-port in various combinations for comprehensive applications.■ Optional loop detection function with an LED to indicate the existence of a loop.■ Supports MII loopback.■ LEDs blink upon reset for LED diagnostics.■ Flexible system configuration by strapping pins, EEPROM, or SMI interface.■ Optional crossover detection and auto correction for plug-and-play.■ Fully compliant with IEEE 802.3/802.3u.■ Optional Forwarding/Filtering reserved control frames (DID= 0180C2000003~0180C200000F).■ Optional Broadcast Input/Output Drop flow control.■ Optional maximum packet length 1536/1552 Bytes.■ Supports two Power Reduction methods: ◆ Power saving mode (automatic cable detection). ◆ Power down mode (via PHY register 0.11).■ Supports QoS function: ◆ QoS based on: (1) Port-based priority (2) 802.1p VLAN tag (3) DiffServ/TOS field in TCP/IP header (4) IP address. ◆ Supports two-level priority queues with various weighting ratios. ◆ Queue service rate based on weighted round robin algorithm. ◆ Optional auto turn off Flow Control for 1~2 sec to avoid head-of-line blocking.■ Supports MII interface connection to external MAC or PHY via 3 modes. ◆ PHY mode MII for router applications. ◆ PHY mode SNI for router applications. ◆ MAC mode MII for HomePNA or other PHY applications.■ Flexible 802.1Q port/tag-based VLAN. ◆ Optional 802.1Q tag-VID aware function. ◆ Optional VLAN Ingress Tag Admit Control. ◆ Optional VLAN Ingress Member set filtering. ◆ Optional ARP VLAN for broadcast packet. ◆ Optional Leaky VLAN for unicast packet.■ Optional 802.1P/Q tag insertion or removal on per-port basis (egress).■ 25MHz crystal input.■ 0.18µm, CMOS technology.■ 128-pin PQFP package.■ 1.8V core voltage.■ Independent power options for 2.5V or 3.3V MII interface.
