HA456 Data Sheet August 1999 File Number 4153.2 120MHz, Low Power, 8 x 8 Video Crosspoint Switch The HA456 is the ﬁrst 8 x 8 video crosspoint switch suitable for high performance video systems.

Its high level of integration signiﬁcantly reduces component count, board space, and cost.

The crosspoint switch contains a digitally controlled matrix of 64 fully buffered switches that connect eight video input signals to any, or all, matrix outputs.

Each matrix output connects to an internal, high-spe
