350MHz, 4 x 1 Video Crosspoint Switch

Description

The HA4344B is a very wide bandwidth 4 x 1 crosspoint

switch ideal for professional video switching, HDTV, com-

puter display routing, and other high performance applica-

tions. This circuit features very low power dissipation,

excellent differential gain and phase, high off isolation, sym-

metric slew rates, fast switching, and latched control signals.

When disabled, the output is switched to a high impedance

state, making the HA4344B ideal for matrix routers.

The latched control signals allow for synchronized channel

switching. When CK1 is low the master control latch loads the

next switching address (A0, A1, CS), while the closed (assum-

ing CK2 is the inverse of CK1) slave control latch maintains the

crosspoint in its current state. CK2 switching low closes the

master latch (with previous assumption), loads the now open

slave latch, and switches the crosspoint to the newly selected

channel. Channel selection is asynchronous (changes with any

control signal change) if both CK1 and CK2 are low.
