altera transceiver support burst mode?

--- Quote Start ---

I would still argue that this is not a burst mode :)

If you have 'traffic' that has bursts, and the interface uses CDR, then at the physical layer, there is a continuous toggling of bits, otherwise CDR will unlock. But, lets not get into a semantics argument.

I don't quite understand what you mean by 'recover a packet in ns scale'. Perhaps you could explain what you are trying to do.

I'm currently investigating using the receivers on the high-speed transceiver blocks for receiving data from high-speed ADCs with >5Gsps lane rates for the digitized data. The interface between the ADC and the transceiver is pretty much 'capture the bits', with no option for sending any protocol 'idle' characters and other such luxuries. If your application is similarly non-standard, perhaps I can help.

Cheers,

Hi Dave,

Have you ever heard about passive optical network. From the ONU to OLT, several clients will share the same physical link. In this case, ONU should send packet in optical layer to OLT in order not to interfere other clients packets. As a result, OLT should recover the clock very fast (packet usually contains preambles) - for detecting the effective packet.

In your case, what kind of transceivers I/O standard do you choose, basic or else? If there is no communication between nodes, do the links keep zero or send some training packets like K28.5..

Thank you for your discussion:)
