Below are the requirements and information that’s not in the datasheet and I’d to get asap.
- Differential clock switching (1MHz to 500MHz)
- Any input to any output
- Any input to any groups of outputs (including all outputs)
- Maintain output-to-output skew per specs (max 75ps) for outputs with same input source
- Local Clock Switching: 8 in x 8 out. Best fit found on TI website is SN65LVCP408 (75ps).
Q1: Can I turn off Equalization/Pre-emphasis for better skew?
Q2: Do you have 3*sigma skew number for the chip? It should be less than 75ps.
- Output frequencies can change on the fly when switching frequency sets
a- No glitch is allowed for outputs with no frequency change
Q3: Is each output mux (circled in red below from p.2 of datasheet) completely independent of the others?
b- Glitch is ok if input changes frequency
c- Glitch is ok if output selects a new input
- Also need bigger Clock Switch: 18 in x 32 out
Q4: Does TI have any Crosspoint Switch to meet this large switch requirement?
Thanks,
Quang
