Hi, for one of the Interfaces am using the DSI Clock as a reference clock for the FTDI link.
I have a question about jitter measurement methodology :
What is the TIE filter setting that was used in scope: Is it a BandPassFilter (Fpclk/40<Jitter Freq < Fpclk/20) or the HPF filter.
Is this TIE Filter setting has to be Enabled for the required jitter or can ignore this setting and apply only CDR settings?
From the info below I see mentioned only CDR scope settings -
- Method = PLL Custom BW
- PLL Type = Type II
- Loop BW = f/40 for dual FPD-Link (where f = PCLK)
- Loop BW = f/20 for single FPD-Link (where f = PCLK)
- Damping = 2
- Target BER = 1e-10
