Set up the evaluation board for a phase jitter measurement:
1. Set the evaluation board DIP switches to enable 3.3V VCCO.
2. Enable the REFA Oscillator input.
3. Disable the REFB Oscillator input.
4. Set the REF_SEL switch to 0.
5. Connect the BANK0 differential outputs to the SIA-3000D differential inputs.
6. From the SIA-3000D GigaView software, execute Pulse Find.
7. Initiate Clock Analysis measurement. Typical phase jitter for the ispClock5406D is 2.5ps.

The ispClock5406D base demo is preprogrammed into the evaluation board, however over time it is likely your
board will be modified. Lattice distributes source and programming files for demonstration designs compatible with
the evaluation board.
To download demo designs:
1. Browse to the ispClock5400D Evaluation Board web page
tions download and save the file.
Extract the contents of Base_Demo_CLK5406.zip to an accessible location on your hard drive.
