GY4102A Fast Toggling
Video Switch
DATA SHEET
CIRCUIT DESCRIPTION
FEATURES
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.
• 20 ns switching time (toggle)
• 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.
