KSZ8081RNBIA-TR
10BASE-T/100BASE-TX Physical Layer Transceiver
The KSZ8081 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 KSZ8081 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 KSZ8081RNx 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 KSZ8081RNA uses a 25MHz crystal to generate all required clocks, including the 50MHz RMII reference clock output for the MAC. The KSZ8081RND is the version that takes in the 50MHz RMII reference clock as the power-up default.
The KSZ8081MLX and KSZ8081MNX offer the Media Independent Interface (MII) for direct connection with MII-compliant Ethernet MAC processors and switches. A 25MHz crystal is used to generate all required clocks.
To facilitate system bring-up and debugging in production testing and in product deployment, parametric NAND tree support enables fault detection between KSZ8081RNA I/Os and the board. Microchip's LinkMD® TDR-based cable diagnostics identify faulty copper cabling.
The KSZ8081RNA and KSZ8081RND are available in 24-pin, lead-free QFN packages. The KSZ8081MNX and KSZ8081RNB are available in 32-pin, lead-free QFN packages. The KSZ8081MLX is available in 48-pin (7mm x 7mm) LQFP package.
