CLC532
High-Speed 2:1 Analog Multiplexer
Features
General Description
■ 12-bit settling (0.01%) - 17ns
■ Low noise - 32µVrms
■ High isolation - 80dB @ 10MHz
■ Low distortion - 80dBc @ 5MHz
The CLC532 is a high-speed 2:1 multiplexer with active input and
outputstages. TheCLC532alsoemploysaclosed-loopdesignwhich
dramaticallyimprovesaccuracy. Thismonolithicdeviceisconstructed
usinganadvancedhigh-performancebipolarprocess.
■ Adjustablebandwidth-190MHz(max)
TheCLC532hasbeenspecificallydesignedtoprovidesettlingtimes
of17nsto0.01%. This,coupledwiththeadjustablenoise-bandwidth,
makes the CLC532 an ideal choice for infrared and CCD imaging
systems. Channel-to-channel isolation is better than 80dB @
10MHz. Lowdistortion(80dBc)andspurioussignallevelsmakethe
CLC532averysuitablechoiceforbothI/Qprocessorsandreceivers.
Applications
■ Infrared system multiplexing
■ CCD sensor signals
■ Radar I/Q switching
■ High definition video HDTV
■ Test and calibration
