Conventions and Nomenclature (Continued)
The terms ‘ set’ , ‘ active’ , and ‘ asserted’ are synonymous.
They do not necessarily infer logic one.
(For example, an active-low signal can be set to logic zero.)
The terms ‘ cleared’ , ‘ inactive’ , and ‘ de-asserted’ are synonymous.
They do not necessarily infer logic zero.
In reference to the ICS1893, the term ‘ Twisted-Pair Receiver’ refers to the set
of Twisted-Pair Receive output pins (TP_RXP and TP_RXN).
In reference to the ICS1893, the term ‘ Twisted-Pair Transmitter’ refers to the
set of Twisted-Pair Transmit output pins (TP_TXP and TP_TXN).

When referring to signals, the terms:
– ‘ FALSE’ , ‘ low’ , or ‘ zero’ represent signals that are logic zero.
– ‘ TRUE’ , ‘ high’ , or ‘ one’ represent signals that are logic one.
Chapter 10, “ DC and AC Operating Conditions”
specifications for ‘ logic zero’ and ‘ logic one’ signals.
In this data sheet, code group names are referred to as ‘ symbols’ and they
are shown between '/' (slashes). For example, the symbol /J/ represents
the first half of the Start-of-Stream Delimiter (SSD1).
Symbol sequences are shown in succession. For example, /I/J/K/
represents an IDLE followed by the SSD.
