Dolby∗ B-C Type Noise Reduction System
Description
The CXA1560 series is a bipolar IC incorporating
stereo Dolby B-C type noise reduction (NR) system.
Five kinds of device are provided due to the
combination of three line output levels and two
packages for various applications.
A reduction in the number of external parts and
small package have been achieved due to the fact
that the spectral skewing circuits are all on-chip.
