INTRODUCTION

1.1

General Description

The KSZ8795CLX is a highly integrated, Layer 2-managed, 5-port switch with numerous features designed to reduce
system cost. It is intended for cost-sensitive applications requiring four 10/100 Mbps copper ports and one 10/100/
1000 Mbps Gigabit uplink port. The KSZ8795CLX incorporates a small package outline, lowest power consumption with
internal biasing, and on-chip termination. Its extensive features set includes enhanced power management, program-
mable rate limiting and priority ratio, tagged and port-based VLAN, port-based security and ACL rule-based packet fil-
tering technology, quality-of-service (QoS) priority with four queues, management interfaces, enhanced MIB counters,
high-performance memory bandwidth, and a shared memory-based switch fabric with non-blocking support. The
KSZ8795CLX provides support for multiple CPU data interfaces to effectively address both current and emerging fast
Ethernet and Gigabit Ethernet applications where the port 5 GMAC can be configured to any of GMII, RGMII, MII and
RMII modes.
The KSZ8795CLX is built upon industry-leading Ethernet analog and digital technology, with features designed to off-
load host processing and streamline the overall design.
• Four integrated 10/100BASE-T/TX MAC/PHYs
• One integrated 10/100/1000BASE-T/TX GMAC with selectable GMII, RGMII, MII, and RMII interfaces
• Small 80-pin LQFP package
A robust assortment of power-management features including Energy Efficient Ethernet (EEE), PME, and Wake-on-
LAN (WoL) have been designed-in to satisfy energy-efficient environments.
KSZ8795CLX supports two management interface modes of SPI and MIIM only, SPI access all registers, MIIM mode
access all PHYs registers through MDC/MDIO interface.

25 MHz Clock Output (Option)
Controlled by the strap pin LED2_0 and the Global Register 11 
Bit[1]. Default is enabled; it is better to disable it if it’s not being 
used.

PME_N

I/O

Power Management Event
This output signal indicates that a WoL event has been detected 
as a result of a wake-up frame being detected. The KSZ8795-
CLX is requesting the system to wake up from low power mode. 
Its assertion polarity is programmable with the default polarity to 
be active-low.

LED2_1

Ipu/O

2

Port 2 LED Indicator 1: 
See Global Register 11 bits [5:4] for details.
Strap Option: Port 5 GMII/MII and RMII mode select
When Port 5 is GMII/MII mode:
PU = GMII/MII is in GMAC/MAC mode. (Default)
PD = GMII/MII is in GPHY/PHY mode.

Note:

When set GMAC5 GMII to GPHY mode, the CRS
and COL pins will change from the input to output.
When set MII to PHY mode, the CRS, COL, RXC
and TXC pins will change from the input to output.

When Port 5 is RMII mode:
PU = Clock mode in RMII, using 25MHz OSC clock and provide 
50 MHz RMII clock from pin RXC5.
PD = Normal mode in RMII, the TXC5/REFCLKI5 pin on the 
port 5 RMII will receive an external 50 MHz clock

Note:

Port 5 also can use either an internal or external
clock in RMII mode based on this strap pin or the set-
ting of the Register 86 (0x56) bit[7].

63

LED2_0

Ipu/O

2

Port 2 LED Indicator 0:
See Global Register 11 bits [5:4] for details.
Strap Option: REFCLKO enable
PU = REFCLK_O (25 MHz) is enabled. (Default)
PD = REFCLK_O is disabled.

Note:

It is better to disable this 25 MHz clock if not provid-
ing an extra 25 MHz clock for the system.

64

LED1_1

Ipu/O

1

Port 1 LED Indicator 1: 
See Global Register 11 bits [5:4] for details.
Strap Option: PLL Clock source select
PU = Still use 25 MHz clock from XI/XO pin even though it is in 
Port 5 RMII normal mode.
PD = Use external clock from pin TXC5 in Port 5 RMII normal 
mode.

Note:

If received clock in Port 5 RMII normal mode has
large clock jitter, one can select the 25 MHz crystal/
oscillator as the switch’s clock source.

LED1_0

Ipu/O

1

Port 1 LED Indicator 0:
See Global Register 11 bits [5:4] for details.
Strap Option: Speed select in GMII/RGMII
PU = 1Gbps in GMII/RGMII.(Default)
PD = 10/100Mbps in GMII/RGMII.

Note:

Programmable through internal registers also.

66

SPIQ

Ipd/O

All

SPI Serial Data Output in SPI Slave Mode:
Strap Option: Serial bus configuration.
PD = SPI slave mode. 
PU = MDC/MDIO mode.

Note:

An external pull-up or pull-down resistor is required.
