Description

The CS8420 is a stereo, digital audio sample-rate converter with AES3 type and serial digital audio inputs and AES3 type and serial digital audio outputs, along with comprehensive control 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 completely asynchronous to the output data with the output data synchronous to an external system clock.

Target applications include CD-R, DAT (digital audio tape), minidisc, DVD and video tape recorder (VTR) equipment, mixing consoles, digital audio transmission equipment, high-quality digital-to-analog and analog-to-digital converters, effects processors and computer audio systems.
