KSZ8081RNA EVAL BOARD

Part Number: KSZ8081RNA-EVAL

Status: No Longer Available

Summary:

The KSZ8081RNA / KSZ8081RND is a 10Base-T/100Base-TX Physical Layer Transceiver with an RMII MAC interface. 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

Summary

The KSZ8081RNA / KSZ8081RND is a 10Base-T/100Base-TX Physical Layer Transceiver with an RMII MAC interface. 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. It also supports Energy Efficient Ethernet (EEE) and Wake-on-LAN (WOL). The difference between the KSZ8081RNA and KSZ8081RND is the default clocking configuration for the RMII interface. The KSZ8081RNA (by default) outputs a 50 MHz RMII Reference clock, while the KSZ8081RND (by default) takes the 50 MHz RMII Reference clock as an input. The KSZ8081RNA / KSZ8081RND comes in a 24-pin, lead-free QFN package and provides an ideal solution for 10Base-T/100Base-TX applications that have tight PCB board space. The KSZ8081RNA and KSZ8081RND Eval Boards (KSZ8081RNA-EVAL and KSZ8081RNDEVAL) provide a convenient platform to evaluate the features of the device. All configuration pins are accessible either by jumpers, test points or interface connectors.
