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-speed (200V/µs), unity gain buffer capable of driving 400Ω and 5pF to ±2V. For applications requiring gain or increased drive capability, the HA456 outputs can be connected directly to two HFA1412 quad, gain of two video buffers, which are capable of driving 75Ω loads.
