Data Sheet Comlinear CLC3800 (R) Triple, Standard Definition Video Amplifier General Description APPLICATIONS n Cable or satellite set-top-box (STB) n Portable DVD players n DVD players n Portable media players with video out n Video on demand n Personal video recorders Competitive Comparison Plots (continued on page 11) The CLC3800 is a triple low cost video amplifier capable of driving 2Vpp into 1 (150), 2 (75), or 3 (50) video loads. The CLC3800 features integrated 8MHz, 4th-order low pass filters designed to cleanly pass standard definition video signals while filtering out noise and other unwanted signals , resulting in a crisper, cleaner video signal. The 4th-order filter provides improved image quality when compared to 2nd-order passive filtering solutions. The CLC3800 video amplifier offers a fixed gain of 6dB. This integrated gain compensates for the voltage drop inherent in properly terminated video loads; ensuring a 1Vpp video signal is present at the load. All three video amplifiers can be driven by DC-coupled signals. Their outputs can drive either AC- or DC-coupled loads. The CLC3800 operates from 3V to 7V supplies and consumes 8.8mA of supply current, making it well suited for battery powered devices. 0.2 Competitor A Normalized Gain (dB) 0.1 Competitor B 0 -0.1 CLC3800 -0.2 Competitor C -0.3 -0.4 Functional Block Diagram VOUT = 2Vpp -0.5 0.1 1 10 Frequency (MHz) Gain IN1 10 OUT1 0 Gain IN3 8MHz, 4th Order Low Pass Filter Normalized Gain (dB) Gain IN2 OUT2 OUT3 -20 Competitor B Competitor C -30 -40 -50 -60 Competitor A VOUT = 2Vpp -70 CLC3800 - 6dB CLC3801 - 9dB CLC3802 - 12dB Rev 1D -10 CLC3800 -80 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.

Many DACs provide a current output that is resistively terminated to ground. These DACs are conveniently DC-coupled to the inputs of the CLC3800 as shown in Figure 1. DC-coupled inputs use fewer components and lowers the overall system cost. Figure 1. Typical Input Configuration DAC Load Resistors per Video DAC/Encoder specs 1 R or Y Video DAC/ Encoder 0.97V 2 G or PB IN1 OUT1 IN2 OUT2 8 7 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 fixed gain of 6dB (for the CLC3800) and the internal level shift of nominally 330mV, the VIN range is generally limited by the output. VIN and VOUT are fully detailed in the Electrical Characteristics section. CLC3800 3 B or PR IN3 OUT3 6 Outputs: AC- or DC-Coupled +3V or +5V 4 1.0F +Vs GND 5 0.1F With DC-coupled loads, AC-coupling capacitors are not used. Match the series termination resistors to the typical 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, preventing video droop across the line, referred to as "tilt". The CLC3800 video amplifier adds a DC offset, raising the input signal by approximately 330mV. For example, when (c)2008-2013 Exar Corporation 12/17 Rev 1D Rev 1D The input termination/source resistance is set by the application. Any value up to several k can be used. Lower values reduce noise, but if higher values are needed, there is little effect on filter shape or distortion performance of the CLC3800. If the CLC3800 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 connect the CLC3800 to the video source, the termination must match the cable impedance which is 75 for standard video cable. Each channel of the CLC3800 can drive either AC- or DCcoupled loads. Each channel can drive single or dual video loads, 150 (1 video load) or 75 (2 video loads). Figure 3 shows the typical configuration for driving either AC- or DC-coupled loads. Comlinear CLC3800 Triple, Standard Definition Video Amplifier The CLC3800 is a 3-channel video amplifiers that operates with single supply voltages from 3V to 7V. They are designed to accept DC-coupled inputs and will drive ACor DC-coupled outputs. Each channel integrates a DC offset, 4th order Butterworth filters, and fixed gain video drivers. The filtering is appropriate for standard definition video signals and has a -3dB cutoff of 8.6MHz. This cutoff provides an excellent compromise between flat in-band response and high frequency noise reduction. The input signals are level shifted prior to the input filters and output amplifiers. 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.

Typical Output Configuration Power Supply Decoupling For optimum performance, power supply decoupling is required. Figure 4 shows the recommended usage of power supply decoupling capacitors. The 0.1F decoupling capacitor must be placed as close to pin 4 as possible, < 0.1" or < 2.5mm, to be effective. The larger, 1F capacitor can be placed further away. 1 2 IN1 OUT1 IN2 OUT2 8 IN3 OUT3 General layout and supply bypassing play major roles in high frequency performance.

In this situation, DC loads may not be possible due to thermal considerations. With single DC loads on all three channels and a 12V supply, the thermal rise is an additional 45 this gives a total temperature rise of about 57. Layout Considerations CLC3800 3 When driving DC loads, the supply current is much higher than in AC applications and care must be taken to dissipate the extra heat generated. The output signal will swing from about 0.3V to 2.3V for full swing video. In the worst case condition, an all white screen with dual DC loads, the additional thermal rise over the quiescent condition is about 20C. An easy way to help distribute this extra heat is to place a ground plane under the part and add ground plane on the bottom of the board immediately under the part with vias between the two planes.
