GY4102A Fast Toggling Video Switch DATA SHEET FEATURES CIRCUIT DESCRIPTION • 20 ns switching time (toggle) 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. • make-before-break switching • 100 MHz at ±0.1dB, bandwidth (flattened) • typically 0.04 dB insertion loss at 1 MHz • typically 0.03 % differential gain at 3.58 MHz • typically 0.01 degree differential phase at 3.58 MHz 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.
