CDCDB2000: SSC active method

Tiger Yeh

Part Number: CDCDB2000
Other Parts Discussed in Thread: CDCE6214

Hi,

According to CDCDB2000 datasheet, it does support PCIe Gen 4 and Gen 5 Common Clock (CC) and Individual Reference (IR) architectures – Spread spectrum-compatible, may I know how to active it and could this adjust SSC percentage?

I cannot find any information in the datasheet except first page.

Please advise.

Thanks and Best regards,

Tiger

Hi Tiger,

The CDCB2000 supports spread spectrum inputs without any additional configuration needed. However, it cannot adjust the SSC percentage from what is provided by the input clock. If you need to do so, it may be worth looking into a SSC-compatible clock generator such as the CDCE6214.

Regards,

Connor

Thanks for reply, Connor.

According to feedback from my customer, it cannot active one output with SSC only if to use SSC clock input.
