**GENERAL DESCRIPTION**

The AD6655 is a mixed-signal intermediate frequency IF receiver consisting of dual 14-bit, 80 MSPS/105 MSPS/125 MSPS/150 MSPS ADCs and a wideband digital downconverter DDC. The AD6655 is designed to support communications applications where low cost, small size, and versatility are desired.
