Dolby∗ B-C Type Noise Reduction System with Built-in S type Switch
The CXA1563M/S is a 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.
• Few external parts
• Spectral skewing circuit are on-chip
• NR ON/OFF, REC/PB, MPX filter ON/OFF,
Dolby S type switches
• Small package (28-pin SOP, 28-pin SDIP)
• Low current consumption 13mA Typ.
(power supply ±6V)
• Dual channel processors
Bipolar silicon monolithic IC
