Convention / Nomenclature
• 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”defines the electrical
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.
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.)
Terms:
‘cleared’,
‘de-asserted’,
‘inactive’
The terms ‘cleared’, ‘inactive’, and ‘de-asserted’are synonymous.
They do not necessarily infer logic zero.
Terms:
In reference to the ICS1893, the term ‘Twisted-Pair Receiver’refers to the set
‘twisted-pair receiver’ of Twisted-Pair Receive output pins (TP_RXP and TP_RXN).
Terms:
In reference to the ICS1893, the term ‘Twisted-Pair Transmitter’refers to the
‘twisted-pair transmitter’ set of Twisted-Pair Transmit output pins (TP_TXP and TP_TXN).
