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.
