Printed Circuit Board Gerber File Modification

Printed Circuit Board Gerber File Modification in terms of grounding, decoupling, and signal routing and can be used as a model when re-layout the ADC section of the electronic PC card in a system. The actual evaluation board layout is usually available from the ADC manufacturer in the form of PCB Circuit Board CAD files (Gerber files).

In many cases, the redesign printed circuit board layout drawing of the various layers appears on the data sheet for the device. It should be pointed out, though, that an evaluation board is an extremely simple system. While some guidelines can be inferred from inspection of the layout, the system that you are designing is undoubtedly more complicated. Therefore, direct use of the layout may not be optimum in larger systems.

Manufacturers of high performance mixed-signal ICs, like Analog Devices, often offer evaluation boards to assist designers in their initial evaluations and PC Board layout. ADC evaluation boards generally contain an on-board low jitter sampling clock oscillator, output registers, and appropriate power and signal connectors. They also may have additional support circuitry such as the ADC input buffer amplifier and external reference.
