Product Details

This control software is for the AD8327. An 8-bit serial word determines the desired output gain over a 48.16 dB range, resulting in gain changes of 6.02 dB/major carry. Full data on the AD8327 and the evaluation board features is available in the AD8327 datasheet available and should be consulted in conjunction with this Technical Note when using the Evaluation Board. On-board components include an input transformer to convert single ended input signals into a differential signal, a diplexer to allow insertion into a cable modem system, and various options for input and output terminations.
