Quality Video Mixer GX4201


Posted on Dec 8, 2012

The modules described in this application note can be used as stand-alone multiplexers for both NTSC/PAL broadcast and any HDTV format applications. In addition, by virtue of their size, their performance and the SIP pin outs, they may be used to form larger n x m, professional video matrices. Each GX4201 device is a 1x1 video crosspoint characterised by a low distortion, unilateral signal path consisting of emitter followers at the input and output with level shifting circuits in between.



The input may be directly driven from cables if a terminating resistor, equal to the characteristic impedance of the cable, is connected from input to ground. The output requires a high impedance load of at least 10 kW to maintain the high degree of d
