CS8420 Datasheet | Cirrus Logic

Features  plete IEC60958, AES3, S/PDIF, EIAJ General Description The CS8420 is a stereo digital audio sample rate converter (SRC) with AES3-type and serial digital audio inputs, AES3-type and serial digital audio outputs, and includes prehensive control ability via a 4-wire microcontroller port. Channel status and user data can be assembled in block-sized buffers, making read/modify/write cycles easy. Digital audio inputs and outputs may be 24, 20, or 16 bits. The input data can be pletely asynchronous to the output data, with the output data being synchronous to an external system clock. The CS8420 is available in a 28-pin SOIC package in both mercial (-10º to +70º C) and Automotive grades (-40º to +85º C). The CDB8420 Customer Demonstration board is also available for device evaluation and implementation suggestions. Please refer to “Ordering Information” on page 93 for ordering information. Target applications include CD-R, DAT, MD, DVD and VTR equipment, mixing consoles, digital audio transmission equipment, high-quality D/A and A/D converters, effects processors, and puter audio systems.
