A circuit that reduces external terminal count of a semiconductor chip, such as a communications chip or other type of chip that requires the generation of configuration codes, by reducing the number of external input terminals required for generating the configuration data. The circuit includes multiplexers, each of which selects output data or configuration data, and includes an output in communication with a respective external output terminal of the chip. A selector is connectable between a selected one of the external output terminals and an external input terminal in communication with a memory to serially input configuration data on that output terminal to the memory to configure the chip. Thus, configuration codes are generated for the chip using a reduced number of external input terminals, thereby reducing the overall external terminal count of the chip. The circuit and chip may be embodied on a network or Ethernet card.

A network device includes a substitutor and a transmitter. The substitutor receives input columns of concurrently received input symbols. Each of the input columns includes one input symbol from each of a plurality of parallel input lanes. The substitutor generates output columns corresponding to the input columns, wherein each of the output columns includes one output symbol for each of a plurality of parallel output lanes. The substitutor replaces the output symbols of a selected column of the output columns with alignment symbols. The selected column is immediately followed by a second column, and the second column is immediately followed by a third column. The substitutor replaces the output symbols of the second column with disposable symbols, and replaces the output symbols of the third column with boundary symbols. The transmitter drives data onto a communications medium in response to the output symbols generated by the substitutor module.

A network device including a receiver, a counter, and a trigger. The receiver is configured to receive idle code groups or false carriers from a remote device. The idle code groups indicate that there is no data to be sent from the remote device, and the false carriers indicate a fault. The counter is configured to count the at least one of the idle code groups or the false carriers detected during a predetermined period. The trigger is configured to (i) assert a first signal if the counter exceeds a predetermined threshold during the predetermined period to resynchronize the network device to the remote device and (ii) count a number of times the first signal is asserted without bringing down a link between the network device and the remote device.

A First-In-First-Out (FIFO) block to buffer a packet having a size is presented. The FIFO block includes a receiver to receive a data frame including the packet and overhead information, and to extract the packet from the data frame. A buffer has a plurality of memory locations to store the packet in a FIFO configuration. A buffer manager, in response to detecting a buffer low packet condition, stalls reads of the packet from the buffer.

A system for encoding signals for a network device includes an encoder configured to encode a transmit control signal. The transmit control signal includes a transmit enable signal in a first half of a cycle of a clock signal, and a transmit error signal in a second half of the cycle of the clock signal. The system includes a control signal transmitter configured to transmit the encoded transmit control signal. The system includes a data signal transmitter configured to transmit a transmit data signal. When neither the transmit enable signal nor the transmit error signal is in a first state in a respective half of the cycle of the clock signal, the transmit data signal includes signaling data.

A physical layer device that is adapted to communicate with a cable medium and that includes an indicator comprises a first input/output terminal and a first transceiver that communicates with the first input/output terminal that is adapted to be connected to the cable medium. A detector detects a power over Ethernet (POE) device. A switching device selectively provides power from a power supply over the cable medium when the detector detects the POE device. A cable tester communicates with the first transceiver, tests the cable medium and determines a cable status, and delays testing of the cable medium when the detector detects the POE device until the switching device provides the power. The indicator indicates at least one of cable testing status during the test and the cable status after the test.
