The NWK914D is a Physical Layer device designed for use in 100BASE-TX applications. The NWK914D has integrated the 100mb/s transceiver, clock and data recovery and NRZI conversion circuitry. It is designed for use in cost effective NIC adapter cards and 100BASE-TX repeater and switch applications.
The device connects through a 5 bit symbol interface directly with any MAC controller that includes the PCS layer, resulting in a simple and cost effective solution. It will also interface with a PCS device such as the NWK935 to form a complete 100BASE-TX Physical Layer for connection to the IEEE 802.3 standard MII interface.
