... Dolby B-C Type Noise Reduction System with Built-in S type Switch Description The CXA1563M bipolar IC incorporating dual channel Dolby B-C type noise reduction (NR) system and Dolby S type switch. Dolby B-C-S type stereo system is completed by using this IC in conjunction with two CXA1417S or two CXA1417Q. A reduction in the number of external parts and small package have been achived due to the fact that the spectral skewing circuits are all on-chip ...

... Application Note The CXA1563M dual channel Dolby B-C type NR IC with a built-in S type (CXA1417S/Q) switch. By using the CXA1563M/S in conjunction with two sets of the CXA1417S/Q encoder unit, a stereo Dolby B-C-S type NR system can be achieved. 1) Power Supply The CXA1563M/S is designed to operate on either single or dual power supply. ...

... MPX ON and MPX OFF. 6) Notes on Operation If the CXA1563M/S is used without being connected to the CXA1417S/Q encoder unit, SIN (Pins 8 and 21) must be connected to GND for dual power supply, and to VCT for single power supply. There is a risk of misoperation if the SIN pins are left open during use. ...
