Hi design gurus!
Sorry if the question sounds silly, but I'm a newbie in the field..... I need to monitor the HOTLink communication between two devices. Following some questions:
1) Can this communication be monitored without acquiring the signal in input and put immediately in output (i.e. without filtering it with dedicated HW)?2) Is there any commercial product having LINUX drivers?
Any help would be appreciated.
THANKS!
IIRC, this is a fairly old chipset (10 yrs +) that enabled some sort of high speed link. It used 10b/8b encoding.
250MBps I think. Just for fun I'd use an active FET probe with 2-3GHz bandwidth and a 50 ohm out. Probe the hotlink channel with the FET and feed a hotlink chip directly with the probe output, assuming there's no nasty DC on there. Have the hotlink chip barf its bytes into a big SRAM and read them out later. It's a PHY layer only, so you would have to know what you're looking at and interpret the data yourself.Hi Cristian,
Not sure if you came up with anything yet, if not, my company has a Hotlink Serial Link Analyzer that we lease and sell. It was developed by our engineers for their own use, and we started getting requests for it so we now offer it as a product. You can read about it at the link below.
Feel free to email me with any questions about it: snipped-for-privacy@greatrivertech.com
