It utilizes a unique mixed-signal design to extend signaling distance while reducing power consumption, and offers HP Auto MDI/MDI-X for reliable detection of and correction for crossover and straight-through cables, eliminating the need to differentiate between crossover and straight-through cables. The KSZ8091RNB supports Energy Efficient Ethernet EEE and Wake-On-LAN WOL , while the KSZ8081RNB does not. The KSZ8081RNB / KSZ8091RNB comes in a 32-pin, lead-free QFN package and provides an ideal solution for 10Base-T/100Base-TX applications that have tight PCB board space. The KSZ8081RNB and KSZ8091RNB Eval Boards KSZ8081RNB-EVAL and KSZ8091RNBEVAL provide a convenient platform to evaluate the features of the device.
