120MHz, Low Power, 8 x 8 Video
Crosspoint Switch
The HA456 is the 鏗乺st 8 x 8 video crosspoint switch suitable
for high performance video systems. Its high level of
integration signi鏗乧antly 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/碌s),
unity gain buffer capable of driving 400鈩?and 5pF to
鹵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鈩?loads.
This crosspoint鈥檚 true high impedance three-state output
capability, makes it feasible to parallel multiple HA456s and
form larger switch matrices.
