NOTES

1. It is recommended that the DDI/DDI input are not driven when the SDI/SDI inputs are being used.

This minimizes crosstalk between the DDI/DDI and SDI/SDI inputs and maximizes performance.

2. These resistors are not needed if the internal pull-up resistors on the GS9020 are used.

3. It is recommended that for new designs VCO components should be returned to the R

for improved ground bounce immunity.
