KSZ8051MNL/RNL
10Base-T/100Base-TX Physical Layer Transceiver

The KSZ8051 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 KSZ8051 is a highly integrated, compact 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.

The KSZ8051MNL offers the Media Independent Interface MII and the KSZ8051RNL offers the Reduced Media Independent Interface RMII for direct connection with MII/ RMII compliant Ethernet MAC processors and switches.
• Single-chip 10Base-T/100Base-TX IEEE compliant Ethernet Transceiver
• MII Interface support KSZ8051MNL
• RMII v1.2 Interface support with 50MHz reference clock output to MAC, and option to input 50MHz reference clock KSZ8051RNL
• Back-to-Back mode support for 100Mbps copper repeater or media converter
• MDC/MDIO Management Interface for PHY register configuration
• Programmable interrupt output
• LED outputs for link, activity and speed status indication

A 25MHz crystal is used to generate all required clocks, including the 50MHz RMII reference clock output for the KSZ8051RNL.

The KSZ8051 provides diagnostic features to facilitate system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support enables fault detection between KSZ8051 I/Os and board. Micrel TDR-based cable diagnostics permit identification of faulty copper cabling.
The KSZ8051MNL and KSZ8051RNL are available in 32pin, lead-free QFN packages See Ordering Information .

Data sheets and support documentation can be found on Micrel’s web site at:
• On-chip termination resistors for the differential pairs
• Baseline Wander Correction
• HP Auto MDI/MDI-X for reliable detection and correction for straight-through and crossover cables with disable and enable option
• Auto-negotiation to automatically select the highest link up speed 10/100 Mbps and duplex half/full
• Power down and power saving modes
• TDR-based cable diagnostics for identification
of faulty copper cabling
• Parametric NAND Tree support for fault detection between chip I/Os and board.
