CIRCUIT DESCRIPTION

The GX4404 is a wideband video multiplexer implemented in bipolar technology. This device is characterized by excellent differential phase and gain in the enabled state, very high off-isolation in the disabled state. Fully buffered unilateral signal paths ensure negligible output to input feedback, while delivering minimal output switching transients through make-before-break switching.

FEATURES

• low differential phase and gain
