NWK914D
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.
