Crystal specifications of the EZ-USB FX2LP

Version 1
    Question: Can the same crystal be used in an EZ-USB FX2LP (CY7C68013A) based device as the one used for an FX2 device?



    When a crystal is used in the design, Cypress recommends that for proper operation the load capacitance of the crystal should be 12 pF. This affects both the load capacitors and the crystal being used. The CY7C68013 requires a crystal with load capacitors that are between 20 pF and 33 pF, while the CY7C68013A requires a crystal with load capacitors of 12 pF. Only for test purposes should an existing BOM that has a crystal with 20 pF to 33pF be used to operate a CY7C68013A at room temperature.  For further information on crystal selection for FX2LP please see the application note:
