Overview

The AD1892 combines a CP-1201, CP-340, IEC-958, AES/EBU, S/PDIF compatible Digital Audio Receiver (DAR) with an asynchronous sample rate converter, allowing the user to specify the output sample rate of the received digital audio infor-mation. The DAR block features support for both Q-channel subcode information (to support CD, CD-R, MD and DAT digital audio formats) as well as Channel Status information. A microcontroller interface, with an SPI compatible serial port, allows full access to the 80-bit Q-Channel subcode buffer and to the 32-bit Channel Status buffer, as well as to the control and status registers. Additionally, key status information from the incoming subframes and the Channel Status buffer is reported on status output pins on the AD1892, so the AD1892 may be used in systems that do not include a microcontroller or microprocessor.
