data sheet c o m l i n e a r CLC3800, clc3801, clc3802 triple, standard defnition video amplifers rev 1a ?2007-2008 cadeka microcircuits llc www.cadeka.com 6 application information basic operation the CLC3800, clc3801, and clc3802 are 3-channel video amplifers that operate with single supply voltages from 3v to 7v. they are designed to accept dc-coupled inputs and will drive ac- or dc-coupled outputs. each channel inte - grates a dc offset, 4th order butterworth flters, and fxed gain video drivers. the fltering is appropriate for standard defnition video signals and has a -3db cutoff of 8.6mhz. this cutoff provides an excellent compromise between fat in-band response and high frequency noise reduction. the input signals are level shifted prior to the input flters and output amplifers. inputs: dc-coupled the inputs must be dc-coupled. many dacs provide a current output that is resistively terminated to ground. these dacs are conveniently dc-coupled to the inputs of the CLC3800, clc3801, or clc3802 as shown in figure 1. dc-coupled inputs use fewer components and lowers the overall system cost. figure 1. typical input confguration the input termination/source resistance is set by the ap - plication. any value up to several k can be used. lower values reduce noise, but if higher values are needed, there is little effect on flter shape or distortion performance of the clc380x. if the clc380x is located on the same board as the video source, and within a few inches, the input termination resistance is determined by the requirements of the video dac or encoder. if a cable is needed to con - nect the clc380x to the video source, the termination must match the cable impedance which is 75 for standard vid - eo cable. the clc380x family of video amplifers add a dc offset, raising the input signal by approximately 330mv. for ex - ample, when 0v is applied to the input, the output becomes approximately 330mv above ground. this offset eliminates sync tip clipping. figure 2 illustrates a typical dc-coupled input signal and resulting output signal after exiting the CLC3800. figure 2. typical dc-coupled signal for CLC3800 the input voltage range is typically 0v to 1.4v for the CLC3800 at 5v supply. due to the internal fxed gain of 6db (for the CLC3800) and the internal level shift of nominally 330mv, the v in range is generally limited by the output. v in and v out are fully detailed in the electrical character - istics section. outputs: ac- or dc-coupled each channel of the CLC3800, clc3801, and clc3802 can drive either ac- or dc-coupled loads. each channel can drive single or dual video loads, 150 (1 video load) or 75 (2 video loads). figure 3 shows the typical confgura - tion for driving either ac- or dc-coupled loads. with dc-coupled loads, ac-coupling capacitors are not used. match the series termination resistors to the typi - cal cable impedance, 75 for standard video cable. keep the output connection to the series termination resistors as short as possible. if driving 2 video loads, place both resistors close to the CLC3800. with ac-coupled loads, use an ac-coupling capacitor of at least 220f in a 75 environment. a value of at least 220f will ensure that low frequencies are passed, pre - venting video droop across the line, referred to as tilt. 0.00v 0.02v input signal 0.32v 1.02v 0.35v output signal 0.97v 2.39v CLC3800 in1 out1 in2 in3 out3 +vs out2 gnd video dac/ encoder r or y b or p r g or p b dac load resistors per video dac/encoder specs +3v or +5v 0.1f 1.0f 8 7 6 5 1 2 3 4
