Pre-emphasis w/o clock
Mar 20th, 2009, 10:41am
 
There is a requirement to implement Tx CML signal Pre-emphasis w/o clock.

Any reference of such kind of implementations?

Does w/o clock mean w/o using a flop inside the pad?  Pre-emphasis in this case is only to boost the rising/falling edge with a short pulse instead of a whole bit.

You cannot do this. For pre-emphasis you need to use the previous bit. which means you need at least 1 flop somewhere in the chain.

Preemphasis signal is at the output. Internal circuits can be any stuff as long as spec is fulfill. Preemphasis can be generated by using 1 bit or half bit method by mean of flipflop
