CDCE62002EVM: Multiple independent clock generator

Part Number: CDCE62002EVM
Other Parts Discussed in Thread: LMK03806, , LMK04610, LMK04832, LMK03328, CDCE925

Hi Team,

A customer is looking for a clock generator with more than 10 channel output and up to 500Mhz frequency. We have proposed LMK03806 buy he wants a clock generator that is capable of generating multiple frequency that is not dependent on the base frequency. Do we have any products that meets this requirement?

Thanks,

Danilo

Hi Team,

The customer already bought CDCE62002EVM but he needs 10 output channels.

Hello,

I am not clear what is meant by not related to base frequency.

If the input frequency and desired outputs are known this would help to narrow down the options, however the LMK04832 and LMK04610 both can provide 10 outputs at > 500 MHz and can be run in single loop or dual loop mode.

Hi Liam,

The customer wants to set the frequencies of 10 channels independently. He doesn't want multiple frequencies from a single clock source using frequency divider.

The email somehow didn't go through. I'm pasting my reply below:

So far we only have integer output dividers. It means that we cannot generate 10 independent output frequencies yet. If the custom wants 2 frequency domains, for example, then we can recommend devices that have 2 PLLs such as LMK03328 and CDCE925 + clock buffers. But if the customer wants 10 absolutely random frequencies then we aren’t able to support that as of now.

Hi Hao,

Thank you for the clarification. I guess the customer will need an MCU and multiple oscillators to meet his requirements.

Thank you for your support.

Danilo
