The CS8416 has a serial digital audio output port and comprehensive control ability through a selectable control port in Software Mode or through selectable pins in Hardware Mode. Channel status data are assembled in buffers, making read access easy. GPO pins may be assigned to route a variety of signals to output pins. A low-jitter clock recovery mechanism yields a very clean recovered clock from the incoming AES3 stream. Stand-alone operation allows systems with no microcontroller to operate the CS8416 with dedicated output pins for channel status data. The CS8416 is available in 28-pin TSSOP, SOIC, and QFN packages in Commercial grade (-10 to +70 C) and Automotive grade (-40 to +85 C). The CDB8416 Customer Demonstration board is also available for device eval- uation and implementation suggestions. Please refer to Ordering Information on page 59 for complete ordering information. Target applications include A/V receivers, CD-R, DVD receivers, multimedia speakers, digital mixing consoles, ef- fects processors, set-top boxes, and computer and automotive audio systems. 2 DS578F3
