ZXFV201, ZXFV202, ZXFV203, ZXFV204 Issue 3 - October 2005 4 www.zetex.com © Zetex Semiconductors plc 2005 Applications information A typical circuit ap plication is shown in Figure 1. This is suitable for 75 /H9024 transmission line connections at both the input and the output and is useful for distribution of wide-band signals such as video via cables. The 75 /H9024 reverse terminating resistor R4 gives the correct matching condition to a terminated video cabl e. The amplifier load is then 150 /H9024 in parallel with the local feedback network. Figure 1 Typical video signal application ci rcuit, gain = 2 (overall gain = 1 for 75/H9024 load The wide bandwidth of this device necessitates some care in the layout of the printed circuit. A continuous ground plane is required under the device and its signal connection paths, to provide the shortest possible ground return paths for signals and power supply filtering. A double-sided or multi-layer PCB construction is required, with plated-through via holes providing closely spaced low-inductance connections from some components to the continuous ground plane. For the power supply filtering, low inductance surface mount capacitors are normally required. It has been found that very good RF decoupling is provided on each supply using a 1000pF NPO size 0805 or smaller ceramic surface mount capacitor, closest to the device pin, with an adjacent 0.1/H9262F X7R capacitor. Other configurations are possible and it may be found that a single 0.01/H9262F X7R capacitor on each supply gives good results. However this should be supported by larger decoupling capacitors elsewhere on the pr inted circuit board. Values of 1 to 10 /H9262F are recommended, particularly where the voltage regulators are located more than a few inches from the device. These larger capacitors are recommended to be solid tantalum electrolytic or ceramic types. Note particularly that the inverting input of this current feedback type of amplifier is sensitive to small amounts of capacitance to ground which occur as part of the practical circuit board layout. This capacitance affects bandwidth, frequency response peaking and pulse overshoot. Therefore to minimize this capacitance, the feedback components R2 and R3 of Figure 1 should be positioned as close as possible to the inverting input connection. 470 470
