ADC Outputs
The data outputs from the ADC are buffered using four
SN74AVC16827 buffers before going to headers J10, J11,
J12, and J13. The ADC and output buffer can p1.8V
or +3.3V output levels. This is selected by the voltage placed
at the ADC driver supply (banana jacks J21 and J22). The
standard headers are on a 100-mil grid, which allows for
easy connection to a logic analyzer.
PHYSICAL DESCRIPTION
This section describes the physical characteristics and PCB
layout of the EVM and lists the components used on the
module.
PCB LAYOUT
The EVM is constructed on a 8-layer, 5.45" x 6.30", 0.062-
inch thick PCB using FR-4 material. A brief description of the
individual layers is shown below. The layer drawings are
attached to the end of this document (Figures 6 - 13).
PARTS LIST
Table VI lists the parts used in constructing the EVM.
