Overview

The KSZ8041NL is a single supply 10Base-T/100Base-TX Physical   Layer   Transceiver,   which   provides   MII/RMII   interfaces  to  transmit  and  receive  data.  An  unique  mixed  signal  design  extends  signaling  distance  while  reducing  power consumption. HP  Auto  MDI/MDI-X  provides  the  most  robust  solution  for  eliminating  the  need  to  differentiate  between  crossover  and straight-through cables. The  KSZ8041NL  represents  a  new  level  of  features  and  performance  and  is  an  ideal  choice  of  physical  layer  transceiver for 10Base-T/100Base-TX applications. The KSZ8041NL comes in a 32-pin.

LAN circuit for RB411 (old model) and RB333 boards.
