Hi all,

soory for the missing text on the previous post:

the ONET4291 and other VCSEL driver are defined as "1-Gbps to 4.25-Gbps Rate-Selectable Limiting Amplifier". Are there any problem in using it at lower tx frequencies?

Thanks

Antonio

The device can be used at lower frequencies. The 1 to 4Gbps was stated for use in Fibre Channel systems.

Alex.

I would like to consult if there is any evaluation board for the ONET4291VA VCSEL driver?

Thanks,

Alan

Alan,

I'm sorry but an evaluation board is not available for this part.

Dear TI-er.

Can I use low datarate below 1Gbps. ?

Hi Kiyoung,

Yes, the ONET4291VA can be used at frequencies below 1Gbps.

However, please note that the datasheet specs are guaranteed only for frequencies between 1Gbps and 4Gbps. So the performance might not be as good at much lower frequencies, but it should work as long as you're using it above the low cutoff freq which is well below 100Mbps.

Hope this helps.

Thanks,

Sri
