The full part number is CMR200TB32.768KDZBTR which is the only crystal on Citizen's website that even remotely looks like the one on the board.
Keep in mind this part has been discontinued (it is not RoHS compliant), so most everyone is moving to a different crystal for RoHS motes. -Joe On 6/27/06, Matthew J Whelan <[EMAIL PROTECTED]> wrote:
Joe, Can you be more specific as to which model the Citizen crystal is? I have tried finding the datasheet on the website, but I cannot find any that match with the #'s I can read on the actual crystal. I would very much appreciate this information as I am trying to work out some issues with sample timing.

It is a standard Citizen crystal. It is +/-30ppm over temperature. > 2) how can i measure power consumption either using usb-powered or > battery-powered motes? Place an ammeter in series with the power source. -Joe _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
