Transceiver Pseudo-CML equivalent circuit?

Hi Dajun,

But I really want to know the maxium sink/source current capability of transimit termination resistors, because I want to terminate the transimit signals using standard 1.5-V CML termination method at the receiver end (the receiver is a programmable delay chip), which will give about a maxium of 12mA sink current through the internal termination resister in ArriaII GX. I really would like to know whether this 12mA current will damage the output buffer of transimitter in FPGA?

I don't know the answer to this. How about you submit a service request to Altera directly, and then post their response here? That would be very helpful.

Cheers,

Dave
