The CLC3800, CLC3801, and CLC3802 feature 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 filters provide 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. If additional gain is required, the CLC3801 video amplifier offers a fixed gain of 9dB and the CLC3802 offers 12dB. All three video amplifiers can be driven by DC-coupled signals. Thier outputs can drive either AC- or DC-coupled loads. These video amplifiers operate from 3V to 7V supplies and consume 8.8mA of supply current, making them well suited for battery powered devices.

They are designed to accept DC-coupled inputs and will drive AC- or 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. 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. raising the input signal by approximately 330mV. For example, 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. 2.39V Comlinear CLC3800, CLC3801, CLC3802 Triple, Standard Definition Video Amplifiers Output Signal 1.02V 0.97V Input Signal 0.35V 0.32V 0.02V 0.00V Figure 2. Typical DC-coupled Signal for CLC3800 DAC Load Resistors per Video DAC/Encoder specs R or Y 1 IN1 OUT1 8 Video DAC/ Encoder G or PB 2 IN2 OUT2 7 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. 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, 150Ω (1 video load) or 75Ω (2 video loads). Figure 3 shows the typical configuration 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 typical cable impedance, 75Ω 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 220μF in a 75Ω environment. A value of at least 220μF will ensure that low frequencies are passed, preventing video droop across the line, referred to as “tilt”.

Any value up to several kΩ 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 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 connect the CLC380x to the video source, the termination must match the cable impedance which is 75Ω for standard video cable. The CLC380x Family of video amplifiers add a DC offset, ©2007-2008 CADEKA Microcircuits LLC Rev 1A www.cadeka.com 6 Data Sheet 1 IN1 OUT1 8 75Ω 220µF 75Ω Video Cables 2.5 75Ω IN2 OUT2 Maximum Power Dissipation (W) 2 7 75Ω 220µF 75Ω 2 CLC3800 3 IN3 OUT3 6 75Ω 220µF 75Ω 1.5 Comlinear CLC3800, CLC3801, CLC3802 Triple, Standard Definition Video Amplifiers 4 +Vs GND 5 1 SOIC-8 AC-Coupling Caps are Optional 0.5 Figure 3.

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 20°C. 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. The CLC3800 is designed primarily for low voltage operation with supply values between 3.0V and 5.5V, but larger supplies can be used. 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°. 1.0µF 0.1µF Figure 4.

CaDeKa has evaluation boards to use as a guide for high frequency layout and as aid in device testing and characterization. Follow the steps below as a basis for high frequency layout: • Include 1µF and 0.1µF ceramic capacitors for power supply decoupling • Place the 6.8µF capacitor
