1 / 50 page  1 Copyright Cirrus Logic, Inc. 2003 (All Rights Reserved) http://www.cirrus.com This document contains information for a new product. Cirrus Logic reserves the right to modify this product without notice. Preliminary Product Information Features Supports 4 digital S/PDIF (IEC60958/IEC61937) inputs 8 Discrete analog inputs using the CS42528 + 3 external CS5351 ADCs for 8 analog channels of input at 48 kHz and 96 kHz 2 Channel upsampling supported 8 Discrete analog outputs from the CS42528 2 Digital S/PDIF (IEC60958/IEC61937) outputs using the CS42528 Mux and XMT958 transmitter on the CS49300 On board SRAM for AAC 5.1 discrete channel decoding In system programmable Flash, capable of holding 16 DSP programs Description The CRD42528 is a reference design for the CS49300 DSP family and the CS42528 CODEC. It supports up to 8 channels of analog input at 48 and 96 kHz, or 2 channels of analog input at 192 kHz. One of four digital S/PDIF inputs may be selected. Additionally, up to 2 channels of digital S/PDIF output and 8 channels of analog output at up to 192 kHz are supported. The on board SRAM is included to allow for AAC 5.1 discrete channel decoding, and on-board flash memory is included to allow in-system programming of up to 16 DSP images. The DSP supports the following algorithms, including (but not limited to) AAC, Dolby Digital (AC-3), Dolby Digital EX, DTS, DTS-ES, DTS Neo:6, Cirrus Original Surround (including COS 6.1), SRS CircleSurround, SRS TruSurround, Pro Logic II, MPEG Multichannel (including EX), and HDCD. The control interface to the CRD42528 is the UDSP System Platform. All control and data I/O is connected to headers, which allows the CRD42528 to be used easily in a end system or as a reference design. A larger block diagram is shown on the next page.
