DEVICE INCLUDES AUDIO PROCESSOR, STEREO DECODER, NOISEBLANKER AND HIGHCUT FUNCTIONS. HIGH PERFORMANCE SIGNAL PROCESSOR NO EXTERNAL COMPONENTS REQUIRED FULLY PROGRAMMABLE VIA I2C BUS LOW DISTORTION LOW NOISE DESCRIPTION The is a high performance signal processor specifically designed for car radio applications. The device includes a complete audioprocessor and a stereo decoder with noiseblanker, stereoblend and all signal processing functions necessary for state-of-the-art as well as future car radio systems. Switching-capacitors design technique allows to obtain all these features without external compoBLOCK DIAGRAM
nents or adjustments. This means that higher quality and reliability walks alongside an overall cost saving. The CSP is fully programmable by I2C bus interface allowing to customize key device parameters and especially filter characteristics. The BICMOS process combined with the optimized signal processing assure low noise and low distortion performances.CASS R CASS L PHONE (MPIN) PHONE GND (MPOUT)
