GENERAL DESCRIPTION

The AD6653 is a mixed-signal intermediate frequency (IF) receiver consisting of dual, 12-bit, 125 MSPS/150 MSPS ADCs and a wideband digital downconverter (DDC). The AD6653 is designed to support communications applications where low cost, small size, and versatility are desired.
