HA4344B
June 1998
350MHz, 4 x 1 Video Crosspoint Switch with Synchronous Controls
Description
The HA4344B is a very wide bandwidth 4 x 1 crosspoint switch ideal for professional video switching, HDTV, computer display routing, and other high performance applications. This circuit features very low power dissipation, excellent differential gain and phase, high off isolation, symmetric 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 (assuming 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.
