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.
