TEF6621_6624: Low-IF analog car radio ARCHIVED

Overview

Archived content is no longer updated and is made available for historical reference only.

Building on the success of NXP's TEF660x and TEF661x families, the TEF662x uses a low-IF architecture to ensure high integration with low complexity. The result is easy design-in and good price/performance ratios.
