480MHz, 1 x 1 Video Crosspoint

Switch with Synchronous Enable

The HA4244 is a very wide bandwidth 1 x 1 crosspoint switch

ideal for professional video switching, HDTV, computer

monitor routing, and other high performance applications. The

circuit features very low power dissipation, excellent

differential gain and phase, high off isolation, symmetric slew

rates, fast switching, and a latched enable signal. When

disabled, the output is switched to a high impedance state,

making the HA4244 ideal for routing matrix equipment.

The latched enable input allows for synchronized channel

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

next EN, while the closed slave control latch maintains the

crosspoint in its current state. CLK switching high closes the

master latch, loads the now open slave latch, and enables or

disables the HA4244 according to the current state of the EN

input.

This crosspoint’s design ensures that it powers up in the

disabled state to eliminate bus contention concerns, and to

minimize supply current draw at power up.

For applications requiring an asynchronous crosspoint

switch, please refer to the HA4201 and HA4600 data sheets.
