KSZ8091MNX/RNB
1.0 INTRODUCTION
1.1 General Description
The KSZ8091 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 KSZ8091 is a highly integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip
termination resistors for the differential pairs, by integrating a low-noise regulator to supply the 1.2V core, and by offering
a flexible 1.8/2.5/3.3V digital I/O interface.
The KSZ8091MNX offers the Media Independent Interface (MII) and the KSZ8091RNB offers the Reduced Media Inde-
pendent Interface (RMII) for direct connection with MII/RMII-compliant Ethernet MAC processors and switches.
Energy Efficient Ethernet (EEE) provides further power saving during idle traffic periods and Wake-on-LAN (WOL) pro-
vides a mechanism for the KSZ8091 to wake up a system that is in standby power mode.
The KSZ8091 provides diagnostic features to facilitate system bring-up and debugging in production testing and in prod-
uct deployment. Parametric NAND tree support enables fault detection between KSZ8091 I/Os and the board. LinkMD®
TDR-based cable diagnostics identify faulty copper cabling.
The KSZ8091MNX and KSZ8091RNB are available in 32-pin, lead-free QFN packages.

Description
Interrupt output: Programmable interrupt output, with Register 1Bh as the
Interrupt Control/Status register, for programming the interrupt conditions and
reading the interrupt status. Register 1Fh, bit [9] sets the interrupt output to
active low (default) or active high.
PME_N output: Programmable PME_N output (pin option 2). When asserted
low, this pin signals that a WOL event has occurred.
Config mode: The pull-up/pull-down value is latched as NAND Tree# at the
deassertion of reset.
See the Strap-In Options - KSZ8091MNX section for details.
This pin has a weak pull-up and is an open-drain.
For Interrupt (when active low) and PME functions, this pin requires an exter-
nal 1.0 kpull-up resistor to VDDIO (digital VDD).
MII mode: MII Transmit Clock output
MII back-to-back mode: No connection
Config mode: The pull-up/pull-down value is latched as PME_EN at the de-
assertion of reset.
See the Strap-In Options - KSZ8091MNX section for details.
MII mode: MII Transmit Enable input
MII mode: MII Transmit Data Input[0] (Note 2-3)
MII mode: MII Transmit Data Input[1] (Note 2-3)
MII mode: MII Transmit Data Input[2] (Note 2-3)
MII Mode: MII Transmit Data Input[3] (Note 2-3)
MII mode: MII Collision Detect output
Config mode: The pull-up/pull-down value is latched as CONFIG0 at the de-
assertion of reset.
See the Strap-In Options - KSZ8091MNX section for details.
MII mode: MII Carrier Sense output
Config mode: The pull-up/pull-down value is latched as CONFIG1 at the de-
assertion of reset.
See the Strap-In Options - KSZ8091MNX section for details.
