1. General Description
The RTL8213B-CG is a QFN40, high-performance media converter featuring low-power integrated 1-port
Giga-PHY that support 1000Base-T, 100Base-TX, and 10Base-T.
RTL8213B
DRAFT Datasheet
For specific applications, the RTL8213B supports one SerDes interface that could be configured as a
SGMII/1000Base-X/100FX interface. The RTL8213B integrates a SRAM for packet buffering, non-
blocking switch fabric, and internal register management into a single CMOS device. Only a 25MHz crystal
is required; an optional EEPROM is offered for internal register configuration.
The embedded packet storage SRAM in the RTL8213B features superior memory management technology
to efficiently utilize memory space. The RTL8213B integrates a 2048-entry look-up table with a 4-way
XOR Hashing algorithm for address searching and learning. The table provides read/write access from the
Slave I2C-like serial Interface, or Slave Media Independent Interface Management (MIIM) Interface. Each
of the entries can be configured as a static entry. Normal entry aging time is between 200 and 400 seconds.
Sixteen Filtering Databases are used to provide Independent VLAN Learning and Shared VLAN Learning
(IVL/SVL) functions.
The Extension GMAC1 of the RTL8213B implements a 1000Base-X/100Base-FX interface.
The RTL8213B supports standard 802.3x flow control frames for full duplex, and optional backpressure
for half duplex. It determines when to invoke the flow control mechanism by checking the availability of
system resources, including the packet buffers and transmitting queues. The RTL8213B supports
broadcast/multicast output dropping, and will forward broadcast/multicast packets to non-blocked ports
only. For IP multicast applications, the RTL8213B can forward IPv4 IGMPv1/v2/v3 and IPv6 MLDv1/v2
snooping protocol packets.
In order to support flexible traffic classification, the RTL8213B supports 48-entry ACL rule check and
multiple actions options. Each port can optionally enable or disable the ACL rule check function. The ACL
rule key can be based on packet physical port, Layer2, Layer3, and Layer4 information. When an ACL rule
matches, the action taken is configurable to Drop/Permit/Redirect/Mirror, change priority value in 802.1q/Q
tag, force output tag format and rate policing. The rate policing mechanism supports from 8Kbps to 1Gbps
(in 8Kbps steps).
In Bridge operation the RTL8213B supports 16 sets of port configurations: disable, block, learning, and
forwarding for Spanning Tree Protocol and Multiple Spanning Tree Protocol. To meet security and
management application requirements, the RTL8213B supports IEEE 802.1x Port-based/MAC-based
Access Control. A 1-set Port Mirroring function is configured to mirror traffic (RX, TX, or both) appearing
on one of the switch’s ports. Support is provided on each port for multiple RFC MIB Counters, for easy
debug and diagnostics.
To improve real-time and multimedia networking applications, the RTL8213B supports eight priority
assignments for each received packet. These are based on (1) Port-based priority; (2) 802.1p/Q VLAN tag
priority; (3) DSCP field in IPv4/IPv6 header; and (4) ACL-assigned priority. Each output port supports a
weighted ratio of eight priority queues to fit bandwidth requirements in different applications. The input
bandwidth control function helps limit per-port traffic utilization. There is one leaky bucket for average
packet rate control for each queue of all ports. Queue scheduling algorithm can use Strict Priority (SP) or
Weighted Fair Queue (WFQ) or Weighted Round Robin (WRR) or mixed.
