CDCM6208: Could replace Si5391?

Part Number: CDCM6208
Other Parts Discussed in Thread: LMK05318B

Hello team,

Do we have similar part to Si5391?

Si5391 has MultiSynth and it can do fractional output divide. So it can output any frequency.

I found CDCM6208 which has fractional output divider from TI. Is it only part we have for fractional output divider?

In this case, could you let me know what feature/spec of CDCM6208 will be selling point over Si5391?

If we have other solution, please let me know.

Best regards,

    Hello,

    CDCM6208 is the only device that has fractional output divider today. Which application is this? If it's Ethernet related then LMK05318B is recommended. It has better jitter than Si5391. If the jitter requirement is not stringent then CDCM6208 is good enough.
