DS90CR286A: Switching characteristics of RxOUT

Takahiro Saito

Part Number: DS90CR286A

Hi team,

I have questions about switching characteristics of RxOUT.

1) Customer is using CLK = 27MHz for RxCLK IN. Is there any reference data available for RSRC and RHRC at CLK = 27MHz?

2) As I looked below thread, I think you don't have any characterization data for output skew between channel to channel.

Is there any reference data available for output skew between channel to channel at CLK=27MHz? It is acceptable for customer just reference data or design estimated value with no guarantee.

Hi,

I am sorry we do not have reference data available for a CLK of 27MHz or output data skew.

Hi Michael-san,

Thank you for your response. I understood you don't have any reference data at 27MHz.

If you have any data in the condition close to CLK=27MHz, I appreceate if you could share it with me.

Datasheet only shows CLK = 66MHz data. How should customer estimate the switching characteristics (RSRC, RHRC) in other condition of 66MHz?

Saito

I am sorry we do not have data other than the 40MHz and 66 MHz already in the datasheet.

Hi Michael-san,

Understood. Can we talk about this by internal email?
