Transceiver data passthrough without jitter (Cyclone IV)

Thank you,

I also have found the link from Altera -

This is very helpful for me.

I need to guarantee synchronous conrol (with minimal jitter) of up to 10 devces working together. To do that we transfer 10-12 control signals at 125 MHz and only 2 of them are used for packet transfering (we have no problems here, just the speed of the "data" channels is slower). We use the tranciever 16-bit data exchange and split it to 16 parallel channels. If we have jitter on a signle receiver, than by the end point of the net we will have much bigger jitter. So, we can't guarantee the synchronous conrol of the devices without solving the problem of jitter.

I also thought about Reverse Serial Loopback (Pre-CDR mode). But this is a question - this is a test mode but if we can we use it for other purposes, for example to connect 10 devices configured with this option to send the same control data to the devices with munimal jitter.
