Introduction
The DRP 3510A decodes digital audio data transmitted according to the Astra Digital Radio standard1). The DRP 3510A has a well-defined interface to the Multistandard Sound Processor MSP 3400C. The DRP 3510A and the MSP 3400C (alternatively MSP 3410D2)) provide all functions that are necessary for ADR and DMX3) decoding. The IC is manufactured in a low-cost 0.8 µm CMOS technology and housed in a 44-pin PLCC package.
