Description

The HA457 is an 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-speed (275V/s), gain of two buffer capable of driving 150 to ±2.5V.

The HA457 will directly drive a double terminated video cable with some degradation of differential gain and phase.Applications demanding the best composite video performance should drive the cable with a unity gain video buffer, such as the HFA1412 quad buffer (see Figure 7).

This crosspoint's three-state output capability makes it feasible to parallel multiple HA457s and form larger switch matrices.
