hi guys, just recently heard about this ADSP egroups, and was kinda hoping if anyone here could help me. i am currently undertaking a project upon which i would interface 4 stereo audio codecs to an ADSP 21065L EZ Kit Lite board through its serial ports. i was wondering if anyone of you could give me a hand on the parts list i would be needing for this project. I would be using the same components that make up the on-board single audio codec. unfortunately, i don't know the manufacturer's number of the parts in this board. more specifically the 3.3V to 5V voltage level converter as well as the 24.5?? MHz clock. well, since i am here already, i would also wish that could you include me in this egroups so i could have updates as well on other applications for the ADSPs. thanks. Jaeson Paras |

MHz clock. The user manual of the 21065 EZLab contains a schematic and a parts list: http://www.analog.com/publications/documentation/VisualDSP/ADSP-21065L-Manual.pd\ f The audio codec is a AD1819A and they use a 74LCX125 for the lines from the codec to the Sharc. -- /* Michael Haertl */ |

It has 4 AC-97 codecs and interfaces directly to many of the ADI EZ-Kit Lites including the 21065L. We use an ADI 2186M to communicate with each codec. The DSP on the EZ-Kit communicates directly with Sport0 on the 2186M in a 16bit or 24 bit TDM format. This is much easier than interfacing AC-97 codecs directly.
