Features - plete EIAJ CP1201, IEC-60958, AES3, S/PDIF-patible Transceiver - +5.0 V Analog Supply (VA+) - +3.3 V or +5.0 V Digital Interface (VL+) - Flexible 3-wire Serial Digital I/O Ports - Adjustable Sample Rate up to 96 k Hz - Low-jitter Clock Recovery - Pin and Microcontroller Read/Write Access to Channel Status and User Data - Microcontroller and Standalone Modes - Differential Cable Driver and Receiver - On-chip Channel Status and User Data Buffer Memories Permit Block Reads & Writes - OMCK System Clock Mode - Decodes Audio CD Q Sub-code General Description The CS8427 is a stereo digital audio transceiver with AES3 and serial digital audio inputs, AES3 and serial digital audio outputs, and includes prehensive control ability through a 4-wire microcontroller port. Channel status and user data are assembled in block-sized buffers, making read/modify/write cycles easy. A low-jitter clock recovery mechanism yields a very clean recovered clock from the ining AES3 stream. Target applications include A/V receivers, CD-R, DVD receivers, multimedia speakers, digital mixing consoles, effects processors, set-top boxes, and puter and automotive audio systems. The CS8427 is available in 28-pin SOIC and TSSOP packages in mercial (-10°C to +70°C) and Automotive (-40°C to +85°C) grades. The CDB8427 Customer Demonstration Board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 49 for plete details.
