The XE1218A is delivered in bare die. The complete FM receiver functionality requires 16 bond wire

connections from the die to the 1st level substrate (for EAR functionality, 18 wire bonds for the line out

connection). The die measures 21.8mm2 (4.9mm x 4.45mm). For prototyping purposes, the XE1218A is also

available in a TQFP44 package, see details on the next page.
