6.5 Obtaining Schematic Updates
Updates to the schematics for the CDB47xxx Development Board can be can be obtained from your local
Cirrus Logic representative as part of a design package including the associated BOM, and layout
artwork. The schematics are provided in Adobe’s portable document format (PDF) and PADS
™
format.
The schematics included in this document are the original Revision A schematics of the CDB47xxS and D
boards and reflect the boards as they were manufactured. Newer schematics may be available that
incorporate feature additions or corrections, and may not match Rev. A hardware.
The latest version of the CDB47xx and CDB47xx_DC schematics is installed with the Cirrus DSP SDK. If
the SDK is installed to C:\CirrusDSP folder, then the schematics are installed as follows:
• CDB47xxx-S are saved in the C:\CirrusDSP\schematics\CDB47xxx-S-Z_<rev> folder.
• CDB47xxx-D are saved in the C:\CirrusDSP\schematics\CDB47xxx-D-Z_<rev> folder.
• CDB47xxx-DC48 are saved in the C:\CirrusDSP\schematics\CDB47xxx-DC48-Z_<rev> folder.
There is no difference in the schematics between CDB47xxx-DC24 and CDB47xxx-DC48 except for the
DSP part populated.
A shortcut to the schematics folder is available from the start menu after installing the SDK:
Start > CirrusDSP > Schematics.
