LMH0303: Minimum Input data rate

David Cole72

Part Number: LMH0303

Hello, I am using the LMH0303 and cannot fin the Minimum Input data rate in the data sheet.

I specifies a maximum, but no minimum. The interface we will be driver requires 160Mbps.

Will this device work?

Hi,

With LMH0303 being a cable driver, it can support arbitrarily lower rate.

But LMH0303 has specific rise/fall time requirement for ST259, ST424, and ST292 as shown below,

With data rate at 160Mbps, you could have rise/fall time outside of the spec, and may need external load caps to slow down the edge.

Thanks

David

David, thank you for the reply. Yes, this makes sense and adding caps if required would not be a problem.
