General Description
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.
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 LinkMD
TDR-based cable diagnostics permit
identification of faulty copper cabling.
The KSZ8051MNL and KSZ8051RNL are available in 32-
pin, lead-free QFN packages (See Ordering Information).
