CIRCUIT DESCRIPTION
FEATURES
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,whiledeliveringminimaloutputswitchingtransients
through make-before-break switching.
• low differential phase and gain
• wide bandwidth, 200 MHz at -3 dB
• small switching transient
• ±4.5 to ±5.5 volts supplies
• individual TALLY outputs
For use in NxM routing matrices, these devices feature a
very high, nearly constant input impedance coupled with
high output impedance in the disabled state. This allows
multiple devices to be paralleled at the inputs and outputs
without additional circuitry.
FUNCTIONAL BLOCK DIAGRAM
The chip is disabled when a logic HIGH is applied to the CS
control pin. In this case, regardless of the ADDRESS data,
the output of the device assumes a high impedance state.
