Pin Description Table
are defined as being negative. Digital signals ending with “B” are defined as being active, or asserted, when at a logic zero (low) level. All other digital
signals (including clocks, buses, and select lines) will be interpreted as being active, or asserted, when at a logic one (high) level.
IDT IDT88K8483
The following table lists the functions of the pins provided on the IDT88K8483. Some of the functions listed are multiplexed onto the same pin.
The active polarity of a signal is defined using a suffix. Analog signals ending with “P” are defined as being positive. Analog signals ending with “N”

Egress Data Bus. This data bus is used to carry egress payload data
and in-band control words.
Egress Data Clock. This clock is associated with the egress data bus
(ED) and the control signal (ECTL).
Egress Control. This signal is high when a control word is present on
the egress data bus (ED) and it is low otherwise.
Egress FIFO Status LVDS. These signals are used to carry egress
round-robin FIFO status information, along with associated error detec-
tion and framing.
Egress Status Clock LVDS. This clock is associated with the egress
FIFO status signals (ESTA).
Egress FIFO Status LVTTL. These signals are used to carry egress
round-robin FIFO status information, along with associated error detec-
tion and framing.
Egress Status Clock LVTTL. This clock is associated with the egress
FIFO status signals (ESTA_T).
