CIRCUIT DESCRIPTION
The GY4102A is a bipolar, monolithic SPDT video switch
incorporating fast control logic. The analog signal path is
characterised by low differential gain, low differential phase
and low insertion loss, coupled with a
±
0.1 dB bandwidth
of typically 100 MHz into a 10 pF load, using an external
series resistor.
In demanding video applications the GY4102A features a
typical switching glitch of less than 30 mV over a 3 ns
period. The device offers toggle rates up to 50 MHz. The
control input is TTL and 5 V CMOS compatible.
