Part Number: TLK10022
Other Parts Discussed in Thread: TLK10081

My customer is handing me Channel Link (4 diff pairs of data and 1 diff pair of clock at 600Mbps LVDS)... I want to know if I can use the TLK10022 to aggregate them into a single high speed channel.

Hi Kouns,

If i understand you correctly, your customer is using multiple channel link 2 devices. Then this customer wants to use TLK10022 to aggregate channel link 2 data streams. Is my understanding correct? Can you please send us a block diagram?

Nasser,

My customer is handing me "Channel Link" which to them means 4 diff pairs of Data and 1 diff pair of Clock... running at 600Mbps.

I need to aggregate that into a single high speed stream ... and then demux it on the other side.

I should have asked about TLK10081 instead of TLK 10022 since I would need to aggregate 5 channels.

Maybe this diagram will help.

Hi Heath,

Apologize for long delay. Based on discussion with colleagues, TLK10081 should be able to do this aggregation. While working on this, we came across other option which may meet your application and provide more flexibility or control. Please below note a link to DS90UB941 serializer as well. Advantage of this approach, is the ability to send back/forward channel information along with the main data channel.
