Comlinear CLC3800 Triple, Standard Definition Video Amplifier Rev 1D Data Sheet Comlinear CLC3800 Triple, Standard Definition Video Amplifier FEATURES General Description n Integrated 4th-order, 8MHz filters The CLC3800 is a triple low cost video amplifier capable of driving 2V into pp n Integrated 6dB video drivers 1 (150), 2 (75), or 3 (50) video loads. The CLC3800 features integrated n 8.8mA total supply current 8MHz, 4th-order low pass filters designed to cleanly pass standard definition n 0.08%/0.04 differential gain/phase video signals while filtering out noise and other unwanted signals , resulting error in a crisper, cleaner video signal. The 4th-order filter provides improved n DC coupled inputs image quality when compared to 2nd-order passive filtering solutions. n AC or DC coupled outputs The CLC3800 video amplifier offers a fixed gain of 6dB. This integrated n DC-coupled outputs remove the need gain compensates for the voltage drop inherent in properly terminated video for AC-coupling capacitors loads ensuring a 1V video signal is present at the load. pp n Each channel can drive 2V into 1, 2, pp All three video amplifiers can be driven by DC-coupled signals. Their outputs or 3 video loads (150, 75 or 50) can drive either AC- or DC-coupled loads. n 0.1% THD The CLC3800 operates from 3V to 7V supplies and consumes 8.8mA of supply n Operates from 3V to 7V supplies current, making it well suited for battery powered devices. n Pb-free SOIC-8 package APPLICATIONS Competitive Comparison Plots (continued on page 11) n Cable or satellite set-top-box (STB) 0.2 n Competitor A Portable DVD players 0.1 Competitor B n DVD players 0 n Portable media players with video out -0.1 CLC3800 n Video on demand n -0.2 Personal video recorders Competitor C -0.3 -0.4 V = 2V OUT pp Functional Block Diagram -0.5 0.1 1 10 Frequency (MHz) 10 Gain IN1 OUT1 0 -10 -20 IN2 Gain Competitor B OUT2 Competitor C -30 -40 -50 IN3 Gain OUT3 -60 Competitor A -70 V = 2V OUT pp 8MHz, 4th Order CLC3800 - 6dB CLC3800 Low Pass Filter CLC3801 - 9dB -80 CLC3802 - 12dB 0.1 1 10 100 Frequency (MHz) Ordering Information Part Number Gain Package Pb-Free RoHS Compliant Operating Temperature Range Packaging Method CLC3800ISO8X 6dB SOIC-8 Yes Yes -40C to +125C Reel Moisture sensitivity level for all parts is MSL-1.
