HA456

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 400

Ω 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 75

Ω loads.

This crosspoint’s true high impedance three-state output

capability, makes it feasible to parallel multiple HA456s and

form larger switch matrices.
