Hi team,

do we have clock translator for below two different condition?

Project 1:

161.132185 CML to 25 LVCMOS

Project2:

156.25 CML to 25 LVCMOS

2*161.132185 CML to 2*25 LVCMOS

Project2:

3*156.25 CML to 3*25 LVCMOS

I'm not sure the implication of 3* and 2*. Are they wanting to take 3 or two inputs and be able to select between them?? Then produce 2 or 3 outputs?

Consider the LMK03318 or CDCM6208.

If they need > 2 inputs, consider using a buffer which could switch between two more inputs and used with above. Otherwise LMK04832 can support 3 inputs in single or dual loop mode and LMK05028 and LMK04616 can support 4 inputs.

Hi Tim, do we have clock translator instead of clock gen?

Hi Bonnie,
Clock translators also bases on PLL circuits. It looks you need 1:1 clock translator, then our CDCI6214 (2:4), CDCM6208 (2:8) have too many outputs. It is recommended to combine the whole board clock tree, then TI's clock generator is more cost save than several separated clock devices.
