Hi,

The 4553 is not available in our db, have a look at the other components and see if there is anything close to it.  The LM331 is not in our db either but you may want to locate the Voltage Control Sine Wave in the "Source" group under the "Controlled Voltage sources" family.  This component allows you to control the sine wave frequency on the output.
