CS8415A 96 kHz Digital Audio Interface Receiver Features General Description Complete EIAJ CP1201, IEC-60958, AES3, The CS8415A is a monolithic CMOS device which re- S/PDIF-compatible Receiver ceives and decodes one of 7 channels of audio data according to the IEC60958, S/PDIF, EIAJ CP1201, or +5.0 V Analog Supply (VA+) AES3. The CS8415A has a serial digital audio output +3.3 V or +5.0 V Digital Interface (VL+) port and comprehensive control ability through a 4-wire microcontroller port. Channel status and user data are 7:1 S/PDIF Input MUX assembled in block-sized buffers, making read access Flexible 3-wire Serial Digital Output Port easy. 8-kHz to 96-kHz Sample Frequency Range A low-jitter clock recovery mechanism yields a very clean recovered clock from the incoming AES3 stream. Low-jitter Clock Recovery Stand-alone operation allows systems with no micro- Pin and Microcontroller Read Access to controller to operate the CS8415A with dedicated Channel Status and User Data output pins for channel status data. Microcontroller and Standalone Modes The CS8415A is available in a 28-pin TSSOP and SOIC Differential Cable Receiver package in both Commerical (-10 to +70C) and Indus- trial grades (-40 to +85 C). The CDB8415A Customer On-chip Channel Status and User Data Buffer Demonstration board is also available for device evalu- Memories ation and implementation suggestions. Please refer to Auto-detection of Compressed Audio Input page 2 for ordering information. Streams Target applications include A/V receivers, CD-R, DVD Decodes CD Q Sub-Code receivers, multimedia speakers, digital mixing consoles, effects processors, set-top boxes, and computer and OMCK System Clock Mode automotive audio systems.
