CY22050 and CY22150 Configuration

Last Updated: November 23, 2011

How is the CY22050 or the CY22150 configured using CyberClocks?


We have the following steps for the configuration:

1. While in CyberClocks, move the cursor over CyClocksRT and click on the CY22050 or CY22150.
2. Enter a reference input frequency and choose crystal or external. If crystal, specify the parallel load capacitance.
3. Enter the desired output frequencies in the yellow highlighted Output boxes.
4. Click the "Calculate" button.

If the desired outputs are white, everything configured correctly. An orange highlighted output means there is some PPM error associated with it. A red highlighted output means it could not be achieved. Note: The CY22050 only has one PLL so all outputs must be related to each other or the reference frequency.

To manually set the frequency and output dividers, click on the "Advanced GUI" button. The "VCO Calculator" in the Option menu can be used to help determine the best PLL frequency and output/divider combination.

Additional information is available in the CyClocksRT Help file.
