General Description
The KSZ8081RND is a single-supply 10BASE-T/100BASE-TX Ethernet physical-layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable.
The KSZ8081RND is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using
on-chip termination resistors for the differential pairs and by integrating a low-noise regulator to supply the 1.2V core,
and by offering 1.8/2.5/3.3V digital I/O interface support.
The KSZ8081RND offers the Reduced Media Independent Interface (RMII) for direct connection to RMII-compliant
MACs in Ethernet processors and switches.
As the power-up default, the KSZ8081RND uses a 25 MHz crystal to generate all required clocks, including the
50 MHz RMII reference clock output for the MAC. The KSZ8081RND is the version that takes in the 50 MHz RMII reference clock as the power-up default.
To facilitate system bring-up and debugging in production testing and in product deployment, parametric NAND tree support enables fault detection between KSZ8081RND I/Os and the board. LinkMD® TDR-based cable diagnostics
identify faulty copper cabling.
The KSZ8081RND is available in 24-pin, lead-free QFN packages.
