General Description
The KSZ8851SNL is a single-chip Fast Ethernet controller
consisting of a 10/100 physical layer transceiver (PHY), a
MAC, and a Serial Peripheral Interface (SPI). The
KSZ8851SNL is designed to enable an Ethernet network
connectivity with any host micro-controller equipped with
SPI interface. The KSZ8851SNL offers the most cost-
effective solution for adding high-throughput Ethernet link
to traditional embedded systems with SPI interface.
The KSZ8851SNL is a single chip, mixed analog/digital
device offering Wake-on-LAN technology for effectively
addressing Fast Ethernet applications. It consists of a Fast
Ethernet MAC controller, SPI interface and incorporates a
unique
dynamic
memory pointer
with
4-byte
buffer
boundary and a fully utilizable 18KB for both TX (allocated
6KB) and RX (allocated 12KB) directions in host buffer
interface.
The KSZ8851SNL is designed to be fully compliant with
the appropriate IEEE 802.3 standards. An industrial
temperature-grade
version of
the
KSZ8851SNL,
the
KSZ8851SNLI is also available (see “Ordering Information”
section).
LinkMD
Physical signal transmission and reception are enhanced
through the use of analog circuitry, making the design
more efficient and allowing for lower-power consumption.
The KSZ8851SNL is designed using a low-power CMOS
process that features a single 3.3V power supply with
options for 1.8V, 2.5V or 3.3V VDD I/O. The device
includes an extensive feature set that offers management
information base (MIB) counters and a fast SPI interface
with clock speed up to 40MHz.
The KSZ8851SNL includes unique cable diagnostics
feature called LinkMD
. This feature determines the length
of the cabling plant and also ascertains if there is an open
or short condition in the cable. Accompanying software
enables the cable length and cable conditions to be
conveniently displayed. In addition, the KSZ8851SNL
supports
Hewlett
Packard
(HP)
Auto-MDIX
thereby
eliminating the need to differentiate between straight or
crossover cables in applications.
