Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required see Applications section for details.
The outputs fairdhild drive AC or DC-coupled single ? Fks7000 the outputs removes the need for output coupling capacitors. F, all outputs AC coupled with ? Frequency Response 10 5 0 -5 2 1 Figure 2. Frequency 0. In addition, the input will be slightly offset to optimize the output driver performance.
The offset is held to the minimum required value to decrease the standing DC current into the load. Typical voltage levels are shown in the diagram below: DC-coupled inputs and outputs 0. If the input signal does not go below ground, the input clamp will not operate. When the input is AC-coupled, the diode clamp will set the sync tip or lowest voltage just below ground.
Ffms7000 worstcase sync tip compression due to the clamp will not exceed 7mV. The input level set by the clamp combined with the internal DC offset will keep the output within its acceptable range.

DAC outputs can also drive these same signals without the AC coupling capacitor. A conceptual illustration of the input clamp circuit is shown below: The internal pull-down resistance is k? Care must be taken not to exceed the maximum die junction temperature. Refer to the Layout Considerations section for more information. The FMS is speci? Following this layout con?
For optimum results, follow the steps below as a basis for high frequency layout: DC-coupled inputs, AC-coupled outputs 0V – 1. F ceramic bypass capacitors? F capacitor within 0. For multi-layer boards, use a large ground plane to help dissipate heat? For 2 layer boards, use a ground plane that extends beyond the device by at least 0.

The value may need to be increased beyond ? F in order to obtain satisfactory operation in some applications. AC-Coupling Caps are Optional. Typical application diagram FMS Rev. Dimensions “D” does not include mold flash, protusions or gate burrs. Mold flash protusions or gate burrs shall not exceed 0. Dimension “E1” does not include interlead flash or protusion.
