TLK10031: Combining a 4-lane JESD204B interface into a 10Gb optical link

Guenter Knittel1

Part Number: TLK10031

Hi,

we have an FPGA-based measurement system. I can implement a 4-lane JESD204B interface (one way, transmit from FPGA) at up to

3.125Gbit/s per lane on that FPGA. I want to combine these lanes and send the data via an SFP 10Gb optical transmitter.

I haven't done much research yet, so I just want to post an general question: could that be done with a TLK10031, or is the

device not suitable for this purpose?

Maybe other suggestions?

Thx

Yes, this TLK part number can be used as a XAUI to SFI PHY SerDes. Refer to its datasheet on TI.com for additional details.

Hi,

I was not talking about XAUI, I was talking about JESD204B on the slow side.

Hi.

Can you confirm the number of lanes, data rate, and encoding type for your JESD204B interface? My assumption was that we would still be dealing with four 3.125Gb/s data streams that are 8B/10B encoded. See TI link below.
