Features and the block diagram.
1.1
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.
