1.1
Overview
The NINJA C/CX (ADM6992C/CX) is a single chip integrating two 10/100 Mbps MDIX TX/FX transceivers with a
two-port 10/100M Ethernet L2 switch controller. Features include a converter mode to meet demanding
applications, such as Fiber-to-Ethernet media converters. The ADM6992CX is the environmentally friendly “green”
package version.
The NINJA C/CX (ADM6992C/CX) supports 16 entries of packet classification and marking or filtering for
TCP/UDP port numbering, IP protocol ID and Ethernet Type. These can be configured either using the EEPROM
or on-the-fly using a small, low-cost micro controller.
On the media side, the NINJA C/CX (ADM6992C/CX)’s 0 and 1 ports support auto-MDIX 10Base-T/100Base-TX
and 100Base-FX as specified by the IEEE 802.3 committee through uses of digital circuitry and high speed A/D.
The NINJA C/CX (ADM6992C/CX) also supports a serial management interface (SMI), which is initialized and
configured using a small low-cost micro controller. It also provides the port status for remote agent monitoring and
a smart counter for reporting port statistics.

Function Description
The NINJA C/CX (ADM6992C/CX) integrates two 100Base-X physical layer devices (PHY), two complete
10BaseT modules, a two-port 10/100 switch controller and memory into a single chip for both 10Mbps and 100
Mbps Ethernet switch operation. It also supports 100Base-FX operations through external fiber-optic transceivers.
The device is capable of operating in either Full-Duplex or Half-Duplex mode in both 10 Mbps and 100 Mbps
operation. Operation modes can be selected by hardware configuration pins, software settings of management
registers, or determined by the on-chip auto negotiation logic.
The NINJA C/CX (ADM6992C/CX) consists of four major blocks:
•
•
•
•
OAM Engine
10/100M PHY Block
Switch Controller Block
Built-in 6Kx64 SSRAM
3.1
10/100M PHY Block
The 100Base-X section of the device implements the following functional blocks:
•
•
•
100Base-X physical coding sub-layer (PCS)
100Base-X physical medium attachment (PMA)
100Base-X physical medium dependent (PMD)
The 10Base-T section of the device implements the following functional blocks:
•
•
10Base-T physical layer signaling (PLS)
10Base-T physical medium attachment (PMA)
The 100Base-X and 10Base-T sections share the following functional blocks:
•
•
•
Clock synthesizer module
MII Registers
IEEE 802.3u auto negotiation
The interfaces used for the communication between the PHY block and switch core is a MII interface.

Ninja C/CX
ADM6992C/CX
Function Description
3.2
Auto Negotiation and Speed Configuration
3.2.1
Auto Negotiation
The Auto Negotiation function provides a mechanism for exchanging configuration information between two ends
of a link segment and automatically selecting the highest performance mode of operations supported by both
devices. Fast Link Pulse (FLP) Bursts provide the signaling used to communicate auto negotiation abilities
between two devices at each end of a link segment. For further details regarding auto negotiation, refer to Clause
28 of the IEEE 802.3u specification. The NINJA C/CX (ADM6992C/CX) supports four different Ethernet protocols,
so the inclusion of auto negotiation ensures that the highest performance protocol will be selected based on the
ability of the link partner.
The auto negotiation function within the NINJA C/CX (ADM6992C/CX) can be controlled either by internal register
access or by the use of configuration pins. If disabled, auto negotiation will not occur until software enables bit 12
in MII Register 0. If auto negotiation is enabled, the negotiation process will commence immediately.
When auto negotiation is enabled, the NINJA C/CX (ADM6992C/CX) transmits the abilities programmed into the
auto negotiation advertisement register at address 04H via FLP bursts. Any combination of 10 Mbps, 100 Mbps,
half duplex, and full duplex modes may be selected. Auto negotiation controls the exchange of configuration
information. Upon successfully auto negotiating, the abilities reported by the link partner are stored in the auto
negotiation link partner ability register at address 05H.
The contents of the “auto negotiation link partner ability register” are used to automatically configure the highest
performance protocol between the local and far-end nodes. Software can determine which mode has been
configured by auto negotiation, by comparing the contents of register 04H and 05H and then selecting the
technology whose bit is set in both registers of highest priority relative to the following list:
1.
2.
3.
4.
100Base-TX full duplex (highest priority)
100Base-TX half duplex
10Base-T full duplex
10Base-T half duplex (lowest priority)
The basic mode control register at address 0H controls the enabling, disabling and restarting of the auto
negotiation function. When auto negotiation is disabled, the speed selection bit (bit 13) controls switching between
10 Mbps or 100 Mbps operation, while the duplex mode bit (bit 8) controls switching between full duplex operation
and half duplex operation. The speed selection and duplex mode bits have no effect on the mode of operations
when the auto negotiation enabled bit (bit 12) is set.
The basic mode status register at address 1H indicates the set of available abilities for technology types (bit 15 to
bit 11), auto negotiation ability (bit 3), and extended register capability (bit 0). These bits are hardwired to indicate
the full functionality of the NINJA C/CX (ADM6992C/CX). The BMSR also provides status on:
•
•
•
Whether auto negotiation is complete (bit 5)
Whether the Link Partner is advertising that a remote fault has occurred (bit 4)
Whether a valid link has been established (bit 2)
The auto negotiation advertisement register at address 04H indicates the auto negotiation abilities to be advertised
by the NINJA C/CX (ADM6992C/CX). All available abilities are transmitted by default, but writing to this register
or configuring external pins can suppress any ability.
The auto negotiation link partner ability register at address 05H indicates the abilities of the Link Partner as
indicated by auto negotiation communication. The contents of this register are considered valid when the auto
negotiation complete bit (bit 5, register address 1H) is set.
3.2.2
Speed Configuration
The twelve sets of four pins listed in Table 10 configure the speed capability of each channel of the NINJA C/CX
(ADM6992C/CX). The logic states of these pins are latched into the advertisement register (register address 4H)

for auto negotiation purpose. These pins are also used for evaluating the default value in the base mode control
register (register 0H) according to Table 10.
In order to make these pins have the same Read/Write priority as software, they should be programmed to
11111111B in case a user wishes to update the advertisement register through software.

Switch Functional Description
The NINJA C/CX (ADM6992C/CX) supports three types of data forwarding mode, store & forward mode, modified
and MII cut-through.
3.3.1
Store & Forward Mode
The NINJA C/CX (ADM6992C/CX) allows switching between different speed media (e.g. 10BaseX and 100BaseX)
in store & forward mode. The entire received frame will be stored into its packet buffer. The NINJA C/CX
(ADM6992C/CX) checks the length and frame check sequence (FCS) of the received frame to prevent the
forwarding of corrupted packets before forwarding to the destination port. A MAC address filtering process can be
enabled to filter local traffic to improve overall network performance. The maximum packet length is up to 9216
bytes in this mode. The maximum packet length is defined in Bit [13:0] of EEPROM register 03H.

Ninja C/CX
ADM6992C/CX
Function Description
3.3.2
Modified Cut-through Mode
The NINJA C/CX (ADM6992C/CX) begins to forward the received packet when it receives the first 64 bytes of the
packet. The latency is about 512 bits time width. The NINJA C/CX (ADM6992C/CX) will not forward fragment
packets. The MAC address learning & filtering should be disabled in this mode, because the received packets may
be corrupted. The maximum packet length is up to 9216 bytes in this mode. The maximum packet length is defined
in Bit [13:0] of EEPROM register 03H.
3.3.3
MII cut-through Mode
The NINJA C/CX (ADM6992C/CX) begins to forward the received packet at the beginning of the received packet.
It provides the minimum latency in this mode. The maximum packet length is 9216 bytes if the clock difference
between MII receive clock and MII transmit clock is 200Ppm.
3.4
Basic Operations
3.4.1
MAC Address Learning & Filtering
The NINJA C/CX (ADM6992C/CX) adopts 4-way associative hash architecture to store the MAC address table. It
can store up to a maximum 1K of MAC addresses.
In store & forward mode, the NINJA C/CX (ADM6992C/CX) receives incoming packets from one of its ports,
searches in the Address Table for the Destination MAC Address, and then forwards the packet to the other port,
if appropriate. If the destination address is not found in the address table, the NINJA C/CX (ADM6992C/CX) treats
the packet as a broadcast packet and forwards the packet to the other ports. If the destination port is the same
with the port where the packet received from, the NINJA C/CX (ADM6992C/CX) treats the packet as a local traffic
packet and discards it.
3.4.2
Address Learning
The NINJA C/CX (ADM6992C/CX) searches for the Source Address (SA) of an incoming packet in the Address
Table and acts as below:
1. The NINJA C/CX (ADM6992C/CX) automatically learns the port number of attached network devices by
examining the Source MAC Address of all incoming packets at wire speed
2. If the SA was not found in the Address Table (a new address), the NINJA C/CX (ADM6992C/CX) waits until
the end of the packet (non-error packet) and updates the Address Table
3. If the SA was found in the Address Table, then the aging value of each corresponding entry will be reset to 0
4. When the DA is in PAUSE mode, then the learning process will be disabled automatically by the NINJA C/CX
(ADM6992C/CX)
3.4.3

The NINJA C/CX (ADM6992C/CX) supports two types of hash algorithms for address learning & filtering. The first
is the CRC-CCITT polynomial method. The 48 bits MAC address is reduced to a 16 bits CRC hash value. Bit [7:0]
of the CRC are used to index the 1K address table. The CRC-CCITT polynomial is
The second is the direct-map method. The 48-bit MAC address is mapped into a 8 bits address spaced by XORmethod to index the 1K address table.
The hash type can be selected by using bit [15] of EEPROM register 03H.

Function Description
3.4.4
Address Recognition and Packet Forwarding
The address learning & filtering process forwards the incoming packets between bridged ports according to the
Destination Address (DA) as below.
1. If the DA is a UNICAST address and the address was found in the Address Table, the NINJA C/CX
(ADM6992C/CX) will check the port number and act as follows:
a) If the port number is equal to the port on which the packet was received, the packet is discarded.
b) If the port number is different from the port on which the packet was received, the packet is forwarded across
the bridge.
2. If the DA is a UNICAST address and the address was not found, the NINJA C/CX (ADM6992C/CX) treats it as
a multicast packet and forwards it across the bridge.
3. If the DA is a Multicast address, the packet is forwarded across the bridge.
4. If the DA is PAUSE Command (01-80-C2-00-00-01), then this packet will be dropped by the NINJA C/CX
(ADM6992C/CX). The NINJA C/CX (ADM6992C/CX) can issue and learn PAUSE commands.
5. The NINJA C/CX (ADM6992C/CX) will forward by default or filter out the packet with DA of (01-80-C2-00-0000), discard the packet with DA of (01-80-C2-00-00-01), filter out the packet with DA of (01-80-C2-00-00-02 ~
01-80-C2-00-00-0F), and forward the packet with DA of (01-80-C2-00-00-10 ~ 01-80-C2-00-00-FF) decided
by EEPROM Reg. 0EH.
3.4.5
Address Aging
Address aging is supported for topology changes such as an address moving from one port to the other. When
this happens, the NINJA C/CX (ADM6992C/CX) internally has 300 seconds timer, after which the address will be
“aged out” (removed) from the address table. Aging function can enabled/disabled by the user. Normally, disabling
the aging function is for security purposes.
3.4.6
Back off Algorithm
The NINJA C/CX (ADM6992C/CX) implements the truncated exponential back off algorithm compliant to the 802.3
CSMA-CD standard. The NINJA C/CX (ADM6992C/CX) will restart the back off algorithm by choosing 0-9 collision
counts. The NINJA C/CX (ADM6992C/CX) resets the collision counter after 16 consecutive retransmitting trials.
3.4.7
Inter-Packet Gap (IPG)
IPG is the idle time between any two successive packets from the same port. The typical number is 96 bits time.
The value is 9.6us for 10Mbps ETHERNET, 960ns for 100Mbps fast ETHERNET, and 96ns for 1000M. The NINJA
C/CX (ADM6992C/CX) provides an option of 92 bit-time gaps in the EEPROM to prevent packet loss when Flow
Control is turned off and the clock P.P.M. value differs.
3.4.8
Illegal Frames
In store & forward mode, the NINJA C/CX (ADM6992C/CX) will discard all illegal frames such as small packets
(less than 64 bytes), oversized packets (greater than the value which is defined in Bit [13:0] of EEPROM register
03H) and bad CRC. Dribbling packing with good CRC value will accept by NINJA C/CX (ADM6992C/CX).
In modified cut-through mode, the NINJA C/CX (ADM6992C/CX) will forward all received packets except for small
packets (less than 64 bytes).
In MII cut-through mode, the NINJA C/CX (ADM6992C/CX) will forward all received packets.
3.4.9
Half Duplex Flow Control
A Back Pressure function is supported for half-duplex operation. When the NINJA C/CX (ADM6992C/CX) cannot
allocate a received buffer for an incoming packet (buffer full), the device will transmit a jam pattern on the port,
thus forcing a collision. Back Pressure is disabled by DISBP which is set during RESETL assertion. A proprietary

Function Description
algorithm is implemented inside the NINJA C/CX (ADM6992C/CX) to prevent the back pressure function causing
HUB partition under a heavy traffic environment and reduce the packet lost rate to increase the whole system
performance.
3.4.10
Full Duplex Flow Control
When a full duplex port runs out of its received buffer space, a PAUSE packet command will be issued by the
NINJA C/CX (ADM6992C/CX) to notify the packet sender to pause transmission. This frame based flow control is
totally compliant to IEEE 802.3x. The NINJA C/CX (ADM6992C/CX) can issue or receive pause packets.
3.4.11
Bandwidth Control
NINJA C/CX (ADM6992C/CX) supports hardware-based bandwidth control for both ingress and egress traffics.
Ingress and egress rates can be limited independently on a per port base. The NINJA C/CX (ADM6992C/CX) uses
8ms at the scale, and the minimum bandwidth control unit is 4 kbit/s so users can configure the rate equal to K *
4 kbit/s, 1<=K<=25000. The NINJA C/CX (ADM6992C/CX) maintains two counters (input and output) for each
port. For example, if users want to limit the rate to 64 kbit/s, they should configure the bandwidth control threshold
to 16. For each time unit, the NINJA C/CX (ADM6992C/CX) will add 64 to the counter and decrease the byte length
when receiving a packet during this period. When the counter is decreased to zero, we can divide the control
behavior into two parts:
1. For the ingress control, the ingress port will not stop receiving packets. If flow control is enabled, Pause packets
will be transmitted, if Back Pressure is enabled, Jam packets will be transmitted, and if the above functions are
not enabled, the packet will be discarded.
2. For the egress control, the egress port will not transmit any packets. The port receiving packets that are
forwarded to the egress port will transmit Pause packets if flow control is enabled, transmit Jam packets if Back
Pressure is enabled, and discard packets if all the above functions are not enabled.
3.4.12
Interrupt
With the use of external CPU support, the NINJA C/CX (ADM6992C/CX) can issue an interrupt to the CPU if any
event defined in SMI interrupt register 10H and SMI interrupt mask register 11H occurs.
3.4.13
Auto TP MDIX function
The normal application in which a Switch connects to a NIC card is by a one-to-one TP cable. If the Switch
connects to other devices such as another Switch, it can be done by two ways. The first is to use a Cross Over TP
cable and the second way is to use an extra RJ45 connector by internally crossing over the TXP/TXN and
RXP/RXN signals. By using the second way, customers can use a one-to-one cable to connect two Switch
devices. All these efforts add extra costs and are not a good solution. The NINJA C/CX (ADM6992C/CX) provides
an Auto MDIX function, which adjusts the TXP/TXN and RXP/RXN automatically on the correct pins. Users can
use one-to-one cabling between the NINJA C/CX (ADM6992C/CX) and other devices either switches or NICs.

Converter Functional Description
3.5.1
Fault Propagation
The NINJA C/CX (NINJA C/CX (ADM6992C/CX)) Media Converter incorporates a Fault Propagation feature,
which allows indirect sensing of a Fiber Link Loss via the 10/100Base-TX UTP connection. Whenever the NINJA
C/CX (NINJA C/CX (ADM6992C/CX)) Media Converter detects a Link Loss condition on the Received fiber (Fiber
LNK OFF), it disables its UTP link pulse so that a Link Loss condition will be sensed on the UTP port to which the

Function Description
NINJA C/CX (NINJA C/CX (ADM6992C/CX)) Media Converter is connected. This link loss can then be sensed
and reported by a Network Management agent in the remote UTP port’s host equipment. This feature will affect
the NINJA C/CX (NINJA C/CX (ADM6992C/CX)) UTP LNK LED.
The NINJA C/CX (NINJA C/CX (ADM6992C/CX)) Media Converter also incorporates a Far End Fault feature,
which allows the stations on both ends of a pair of fibers to be informed when there is a problem with one of the
fibers. Without Far End Fault, it is impossible for a fiber interface to detect a problem that affects only its
Transmitting fiber.
When Far End Fault is supported and enabled, a loss of received signal (link) will cause the transmitter to generate
a Far End Fault pattern in order to inform the device at the far end of the fiber pair that a fault has occurred. Unless
Fiber Link Loss occurs or if the UTP port link fails, the NINJA C/CX (NINJA C/CX (ADM6992C/CX)) Media
Converter will also generate a Far End Fault pattern in order to inform the device at the far end of the fiber pair
that a fault has occurred.
3.6
Serial Management Interface (SMI) Register Access
The SMI consists of two pins, management data clock (SDC) and management data input/output (SDIO). The
NINJA C/CX (ADM6992C/CX) is designed to support an SDC frequency up to 25 MHz. The SDIO line is bidirectional and may be shared with other devices.
The SDIO pin requires a 1.5 K pull-up which, during idle and turnaround periods, will pull SDIO to a logic one state.
NINJA C/CX (ADM6992C/CX) requires a single initialization sequence of 35 bits of preamble following powerup/hardware reset. The first 35 bits are preamble consisting of 35 contiguous logic one bits on SDIO and 35
corresponding cycles on SDC. Following preamble is the start-of-frame field indicated by a <01> pattern. The next
field signals the operation code (OP): <10> indicates read from management register operation, and <01>
indicates write to management register operation. The next field is the management register address. It is 10 bits
wide and the most significant bit is transferred first.

During Read operation, a 2-bit turn around (TA) time spacing between the register address field and data field is
provided for the SDIO to avoid contention. Following the turnaround time, a 32-bit data stream is read from or
written into the management registers of the NINJA C/CX (ADM6992C/CX).

3.6.1
Preamble Suppression
The SMI of NINJA C/CX (ADM6992C/CX) supports a preamble suppression mode. If the station management
entity (i.e. MAC or other management controller) determines that all devices which are connected to the same
SDC/SDIO in the system support preamble suppression, then the station management entity needs not to
generate preamble for each management transaction. The NINJA C/CX (ADM6992C/CX) requires a single
initialization sequence of 35 bits of preamble following power-up/hardware reset. This requirement is generally met
by pulling-up the resistor of SDIO. While the NINJA C/CX (ADM6992C/CX) will respond to management accesses
without preamble, a minimum of one idle bit between management transactions is required.
When NINJA C/CX (ADM6992C/CX) detects that there is address match, then it will enable Read/Write capability
for external access. When address is mismatched, then NINJA C/CX (ADM6992C/CX) will tristate the SDIO pin.

3.7
Reset Operation
The NINJA C/CX (ADM6992C/CX) can be reset either by hardware or software. A hardware reset is accomplished
by applying a negative pulse, with duration of at least 100 ms to the RC pin of the NINJA C/CX (ADM6992C/CX)
during normal operation to guarantee internal SSRAM is reset properly.
Hardware reset operation samples the pins and initializes all registers to their default values. This process includes
re-evaluation of all hardware configurable registers. A hardware reset affects all embedded PHYs in the device.
Software reset can reset all embedded PHY and it does not latch the external pins nor reset the registers to their
respective default values. This can be achieved by writing FF to EEPROM Reg.3FH.
Logic levels on several I/O pins are detected during a hardware reset to determine the initial functionality of NINJA
C/CX (ADM6992C/CX). Some of these pins are used as output ports after reset operation.
Care must be taken to ensure that the configuration setup will not interfere with normal operations. Dedicated
configuration pins can be tied to VCC or Ground directly. Configuration pins multiplexed with logic level output
functions should be either weakly pulled up or weakly pulled down through external resistors.
3.7.1
Write EEPROM Register via EEPROM Interface
To write data into desired EEPROM Register via EEPROM interface.
If external EEPROM 93C46 or 93C66 exists, any WRITE programming instructions after EWEN instruction is
executed can be updated effectively on EEPROM content and NINJA C/CX (ADM6992C/CX) internal mapping
register on the same time.
If no external EEPROM exists, EECS/EECK/EEDI must be kept tristate at least 100ms after hardware reset. Any
WRITE programming instructions after EWEN instruction is executed can be updated effectively on NINJA C/CX
(ADM6992C/CX) internal mapping register. Please notice that NINJA C/CX (ADM6992C/CX) can only identify
93C66-programming instructions if no external EEPROM.
