NOTES:

1. The parameters listed in this table are controlled via design or, process parameters and are not directly tested. These parameters are

characterized upon initial design and after major process and/or design changes.

2. Measured from 3.2V on the EFI waveform to 1.0V on the CLK.

3. Measured from 0.8V on the EFI waveform to 3.6V on the CLK.

4. Measured from 3.6V on the X1 input to 3.6V on the CLK.
