Analog devices offers 16 x 16 video crosspoint switches, ad8114 and ad8115. They feature on-chip integration to save design time it enhances performance with 256 switch points, 16 output amplifiers, and control logic. The switches have 16 independent input and output buffersthat are able to place into a high impedance state for paralleling crosspoint outputs, so that output bus is not loaded by off-channels.
