5-Port 10/100M Ethernet Router Network Processor 0 Track ID: JATR-3375-16 Rev. 1.1
1. General Description
The RTL8197D is an integrated System-on-a-Chip (SoC) Application Specific Integrated Circuit (ASIC)
L2 5-Port Ethernet switch. An RLX5281 CPU is embedded and the clock rate can be up to 660MHz. To
improve computational performance, a 64Kbyte I-Cache, 32Kbyte D-Cache, 16Kbyte I-MEM, and
8Kbyte D-MEM are provided. A standard 5-signal P1149.1 compliant EJTAG test interface is supported
for CPU testing and software development.
The RTL8197D provides five ports (ports 0~4), integrated with five physical layer transceivers for
10Base-T and 100Base-TX. Each port of the RTL8197D may be configured as a LAN or WAN port. Port
0 supports an external MAC interface that could be an GMII/RGMII/MII interface type to work with an
external MAC or PHY transceiver.
The RTL8197D supports flexible IEEE 802.3x full-duplex flow control and optional half-duplex
backpressure control. For full-duplex, standard IEEE 803.3x flow control will enable pause ability only
when both sides of UTP have auto-negotiation ability and have enabled pause ability. The RTL8197D
also provides optional forced mode IEEE 802.3x full-duplex flow control. Based on optimized packet
memory management, the RTL8197D is capable of Head-Of-Line blocking prevention.
L2 Switch Features: The RTL8197D contains a 1024-entry address look-up table with a 10-bit 4-way
XOR hashing algorithm for address searching and learning. Auto-aging of each entry is provided and the
aging time is around 300~450 seconds.
The RTL8197D supports IEEE 802.3az, also known as Energy Efficient Ethernet (EEE). IEEE 802.3az
operates with the IEEE 802.3 Media Access Control (MAC) Sublayer to support operation in Low Power
Idle mode. When the Ethernet network is in low link utilization, EEE allows systems on both sides of the
link to save power. Green Ethernet power saving provides: link-on and dynamic detection of cable length,
and dynamic adjustment of power required for the detected cable length. This feature provides high
performance with minimum power consumption. The RTL8197D also implements link-down power
saving on a per-port basis, greatly cutting power consumption when the network cable is disconnected.
For peripheral interfaces, two 16550-compatible UARTs are supported, and a 16-byte FIFO buffer is
provided. Both USB 2.0 host and USB OTG (On-The-Go) controllers are embedded in the RTL8197D to
provide EHCI and OHCI 1.1 compliant host and OTG functionality. In addition, two USB PHYs are
embedded in the RTL8197D.
An MDI/MDIX auto crossover function is supported. For accessing high-speed devices, the RTL8197D
provides two PCI Express hosts to access a PCI Express interface. Up to two PCI Express devices are
supported via this interface on the RTL8197D.
The RTL8197D requires only a single 25MHz crystal or 40MHz clock input for the system PLL. The
RTL8197D also has two hardware timers and one watchdog timer to provide accurate timing and
watchdog functionality. For extension and flexibility, the RTL8197D supports up to 46 GPIO pins.

4.3. Warning
4.3.1 Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator &
your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only.

(The user manual of transmitter devices equipped with detachable antennas shall contain the following
information in a conspicuous location: )
This device has been designed to operate with an antenna having a maximum gain of 2.39 dBi. Antenna
having a higher gain is strictly prohibited per regulations of Industry Canada. The required antenna
impedance is 50 ohms.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

informations suivantes dans un endroit bien en vue:)
Ce dispositif a été conçu pour fonctionner avec une antenne ayant un gain maximum de 2.39 dBi. Une
antenne à gain plus élevé est strictement interdite par les règlements d'Industrie Canada. L'impédance
d'antenne requise est de 50 ohms.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peutfonctionner avec une
antenne d'un type et d'un gain maximal (ou inférieur) approuvé pourl'émetteur par Industrie Canada. Dans
le but de réduire les risques de brouillage radioélectriqueà l'intention des autres utilisateurs, il faut choisir
le type d'antenne et son gain de sorte que lapuissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse
pas l'intensité nécessaire àl'établissement d'une communication satisfaisante.
