fan-out

fan-out

[′fan‚au̇t]

(electronics)

The number of parallel loads that can be driven from one output mode of a logic circuit.

fan-out

(electronics)

The number of logic gate inputs that can be driven from a single gate output of the same type. Circuit designers need to add extra buffers if a signal goes to more inputs than the fan-out of the gate that produces it allows.

In reversible design fan-out and feedback are not allowed [9, 10].

This reversible gate can be used as fan-out generator [8] and we use it in the proposed design.

Because fan-out is not considered reversible, in this design we have a fan-out generation circuit for generating the necessary inputs.

After generating fan-out signals, the required partial products are generated by means of Peres gates as reversible AND operation.

Fine-pitch BGAs are making PCB designers think twice about implementing traditional fan-out patterns.

However, the main problem is the BGA's narrow pitch of 0.4 mm, and the problem that routing is not allowed on the top layer, except for fan-outs. The goal here is to fan-out the BGA without adversely affecting board fabrication.

It's not possible to have the traditional dog-bone fan-out pattern due to the extremely small space between the pads.

The fan-out method devised here avoids using a high-end technique and doesn't jeopardize signal integrity.

Handling fan-outs, or preventing slivers of unconnected metal, are two examples that spring to mind, where some tools can come up with a different solution each time.
