Definition
Aggressor
A network that transmits a coupled signal to another network.
Anti-etch
Any plane-split, void or cutout in a VCC or GND plane.
Bus Agent
A component or group of components that, when combined, represent a
single load on the AGTL+ bus.
Crosstalk
The reception on a victim network of a signal imposed by aggressor
network(s) through inductive and capacitive coupling between the
networks.
Backward Crosstalk - Coupling that creates a signal in a victim network
that travels in the opposite direction as the aggressor‟s signal.
Forward Crosstalk - Coupling that creates a signal in a victim network that
travels in the same direction as the aggressor‟s signal.
Even Mode Crosstalk - Coupling from a signal or multiple aggressors when
all the aggressors switch in the same direction that the victim is
switching.
Odd Mode Crosstalk - Coupling from a signal or multiple aggressors when
all the aggressors switch in the opposite direction that the victim is
switching.

Flight Time
Flight time is a term in the timing equation that includes the signal
propagation delay, any effects the system has on the TCO (time from
clock-in to data-out) of the driver, plus any adjustments to the signal at
the receiver needed to ensure the setup time of the receiver. More
precisely, flight time is defined as:
The time difference between a signal at the input pin of a receiving agent
crossing the switching voltage (adjusted to meet the receiver
manufacturer‟s conditions required for AC timing specifications; i.e.,
ringback, etc.) and the output pin of the driving agent crossing the
switching voltage when the driver is driving a test load used to specify the
driver‟s AC timings.
Maximum and Minimum Flight Time - Flight time variations are caused by
many different parameters. The more obvious causes include variation of
the board dielectric constant, changes in load condition, crosstalk, power
noise, variation in termination resistance, and differences in I/O buffer
performance as a function of temperature, voltage, and manufacturing
process. Some less obvious causes include effects of Simultaneous
Switching Output (SSO) and packaging effects.
Maximum flight time is the largest acceptable flight time a network will
experience under all conditions.
Minimum flight time is the smallest acceptable flight time a network will
experience under all conditions.

communication between two devices via a bi-directional infrared data
