ICS1893CF
General
The ICS1893CF is a low-power, physical-layer device (PHY)
that supports the ISO/IEC 10Base-T and 100Base-TX
Carrier-Sense Multiple Access/Collision Detection
(CSMA/CD) Ethernet standards, ISO/IEC 8802-3.
The ICS1893CF is intended for MII, Node applications that
require the Auto-MDIX feature that automatically corrects
crossover errors in plant wiring.
The ICS1893CF incorporates Digital-Signal Processing (DSP)
control in its Physical-Medium Dependent (PMD) sub layer. As
a result, it can transmit and receive data on unshielded
twisted-pair (UTP) category 5 cables with attenuation in
excess of 24 dB at 100MHz. With this ICS-patented
technology, the ICS1893CF can virtually eliminate errors from
killer packets.
The ICS1893CF provides a Serial-Management Interface for
exchanging command and status information with a
Sta t i o n - M a n a g e m e n t ( S TA) e n t i t y. T h e I CS 1 8 9 3 C F
Media-Dependent Interface (MDI) can be configured to
provide either half- or full-duplex operation at data rates of 10
Mb/s or 100Mb/s.
The ICS1893CF is available in a 300-mil 48-lead SSOP
pa c k ag e. T he I CS 18 9 3C F s h ar es t he s a m e p r o v en
performance circuitry with the ICS1893BF and is a pin-for-pin
replacement of the 1893BF.

With reference to the MII/SI pin, the acronym ‘SI’ has multiple meanings.
•
Generically, SI means 'Stream Interface', and is documented as such in this data
sheet.
•
However, when the MAC Interface is configured for:
– 10M operations, SI is an acronym for 'Serial Interface'.
– 100M operations, SI is an acronym for 'Symbol Interface'.

Table 2-1.
Bits
Conventions and Nomenclature
Item
Convention / Nomenclature
•
A bit in a register is identified using the format ‘register.bit’. For example, bit
•
•
0.15 is bit 15 of register 0.
When a colon is used with bits, it indicates the range of bits. For example,
bits 1.15:11 are bits 15, 14, 13, 12, and 11 of register 1.
For a range of bits, the order is always from the most-significant bit to the
least-significant bit.
Code groups
Colon (:)
Within this table, see the item ‘Symbols’
Within this table, see these items:
•
‘Bits’
•
‘Pin (or signal) names’
Numbers
•
As a default, all numbers use the decimal system (that is, base 10) unless
•
Pin (or signal) names
followed by a lowercase letter. A string of numbers followed by a lowercase
letter:
– A ‘b’ represents a binary (base 2) number
– An ‘h’ represents a hexadecimal (base 16) number
– An ‘o’ represents an octal (base 8) number
All numerical references to registers use decimal notation (and not
hexadecimal).
•
All pin or signal names are provided in capital letters.
•
A pin name that includes a forward slash ‘/’ is a multi-function, configuration
pin. These pins provide the ability to select between two ICS1893CF
functions. The name provided:
– Before the ‘/’ indicates the pin name and function when the signal level
on the pin is logic zero.
– After the ‘/’ indicates the pin name and function when the signal level on
the pin is logic one.
For example, the HW/SW pin selects between Hardware (HW) mode and
Software (SW) mode. When the signal level on the HW/SW pin is logic:
– Zero, the ICS1893CF Hardware mode is selected.
– One, the ICS1893CF Software mode is selected.
•
An ‘n’ appended to the end of a pin name or signal name (such as
RESETn) indicates an active-low operation.
•
When a colon is used with pin or signal names, it indicates a range. For
example, TXD[3:0] represents pins/signals TXD3, TXD2, TXD1, and TXD0.
•
When pin name abbreviations are spelled out, words in parentheses
indicate additional description that is not part of the pin name abbreviation.
Registers
•
A bit in a register is identified using the format ‘register.bit’. For example, bit
•
•
0.15 is bit 15 of register 0.
All numerical references to registers use decimal notation (and not
hexadecimal).
When register name abbreviations are spelled out, words in parentheses
indicate additional description that is not part of the register name
abbreviation.
