MSC1210Y5: Ceramic resonator usage?

Part Number: MSC1210Y5

We would like to know TI’s recommendations for ceramic resonators.  The frequency is 11.0592 MHz.  I was wondering whether TI had done any testing with ceramic resonators (at any frequency) and would make any recommendations.

  • Hi Radar,

    The MSC1210 is a design greater than 15 years old.  The oscillator is designed for a crystal.  There is a crystal app note on the ftp site:

    ftp://ftp.ti.com/pub/data_acquisition/MSC_CD-ROM/Application_Notes/SBAA123_Using_Crystal_Oscillators_with_MSC12xx.pdf

    Crystal startup and oscillation is very layout dependent.  Ceramic resonators we have found can be an even larger issue with a number of our products.  As such, if a customer wants to use a ceramic resonator it is recommended that the product be submitted to the resonator manufacturer for testing and qualification.  We do not have data specific to the MSC1210 with the use of a ceramic resonator.

    Best regards,

  • Please remove ceramic resonator references from the device data sheet.
  • Hi Radar,

    Ceramic resonators can be used, there just isn't any specific recommendations (your initial question was with respect to testing and recommendations). Any ceramic resonator should be thoroughly tested in the system. I would give the same advice for crystals as well with respect to testing. The only way of truly knowing how well the oscillator will work is by testing the layout. There are many newer resonator and crystals, especially for surface mount, that were not available 15-20 years ago.

    All development work on the MSC products was halted some number of years ago, and any applications support is very limited as we have limited support resources available. This also includes software tools, examples and EVMs.

    Best regards,
