Signal references
⢠When referring to signals, the terms:
â âFALSEâ, âlowâ, or âzeroâ represent signals that are logic zero.
â âTRUEâ, âhighâ, or âoneâ represent signals that are logic one.
⢠Chapter 9, âDC and AC Operating Conditionsâ defines the electrical
specifications for âlogic zeroâ and âlogic oneâ signals.
Symbols
⢠In this data sheet, code group names are referred to as âsymbolsâ 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.
Terms:
âsetâ,
âactiveâ,
âassertedâ,
The terms âsetâ, âactiveâ, and âassertedâ are synonymous.
They do not necessarily infer logic one.
(For example, an active-low signal can be set to logic zero.)
Terms:
âclearedâ,
âde-assertedâ,
âinactiveâ
The terms âclearedâ, âinactiveâ, and âde-assertedâ are synonymous.
They do not necessarily infer logic zero.
Terms:
âtwisted-pair receiverâ
In reference to the ICS1893Y-10, the term âTwisted-Pair Receiverâ refers to the
set of Twisted-Pair Receive output pins (TP_RXP and TP_RXN).
Terms:
In reference to the ICS1893Y-10, the term âTwisted-Pair Transmitterâ refers to
âtwisted-pair transmitterâ the set of Twisted-Pair Transmit output pins (TP_TXP and TP_TXN).
