Hi, Actually i am using rocketio wizard 7.1.I want to do conversion of 8 bit parallel data into serial stream using rocketio mgt for 3.125 gbps. What frequency i have to apply on refclk,rxusrclk,rxusrclk2,txusrclk,txusrclk2?? I do not want to use crc and 8b10b module of rocketio mgt. Please suggest me any simple application for that.

Hi. I am trying to establish a communication between two RocketIO driven Virtex2P FPGAs. I am currently simulating the design running into the following problem: When I set the RocketIO Transmitters (Xilinx GT_CUSTOM) into parallel loopback mode everything is fine (received data = sent data). Whenever I set it into serial loopback mode (or try to communicate with another RocketIO receiver) I...

Hi all, Did some company already implemented G.709 OTU-2 on Virtex-4 using the RocketIO? In other words: the maximum bitrate of RocketIO is 10.3125 but OTU-2 is 10.709. Should Virtex-4 be definitively excluded or are there some tricks to achieve that challenge? Cheers Mehdi

I'm considering the V2pro series for several projects. I've heard from someone with experience that there are problems with the RocketIO when a lot of other things are happening on the chip. This is thought to be a problem with the V2pro package. The evaluation boards only implement the RocketIO without a lot of other things going on in the part. Can anyone provide an example of ...

Has anyone had any sucess in using RocketIO from Virtez 2 or Virtex 4 for Serial ATA applications? From the information collected on various news groups and web sites, my understanding is SATA OOB cannot be done using RocketIO in Virtex 2s. Did any one try Virtex 4s? What is the comment from FPGA gurus out there? - sg

Anyone have experience with directly driving a cable with RocketIO? I am interested in any information/experiences/advice regarding linking two FPGAs via RocketIO over a cable. I have seen some signal characterization information for high-speed links over copper, but usually less than 800Mhz. I believe my implementation would use a a less than 1 meter, but would like to know it works at 3, 5,...

Dear all, I'm in the early stages of designing a board with a Virtex-4 FX on it which we are planning to use for development involving RocketIO. The other guys on the team have stated that it would be "really useful" to have the clock for the RocketIO fed from a programmable oscillator. We have a Virtex-II FX development board that has a similar arrangement, using a ICS8442 low jitt...

Hi, I'm trying to implement rocketio on xilinx fpga. Is there a way to simulate it using modelsim XE. I know for the PE, SE version its using smartmodels or generating libraries. Also is there any basic programs using rocketio, architect (wizard can't simulate, core generator can't compile libraries for modelsim, and the program that came with the eval board uses multiple buses, memory ...

Hi, I am presently working on a design involving a RocketIO in a Virtex II Pro. I am looking at reference clocks for the PLL of the RocketIO meeting among other things the jitter requirement related to the serial link frequency. I am wondering how to combine deterministic jitter and random jitter parameters of the oscillator. Is the total jitter the rms value of the two parameters or ...

Has anyone been able to dynamically change the SerDes speed on the V4FX RocketIO. I've been able to get the RocketIO to operate correctly at both SDR rates (2.5GHz) and DDR (5GHz) rates using static parameters but when I try to change the speed dynamically the RocketIO enter a state where they never lock up at any speed. The only way to get them to operate again is to reload the bit stream. ...

Hi All, I reviewed LocalLink and Aurora protocol and it does not specifically say anything about RocketIO tranceivers. So I assumed that it could be implemented by using LVDS pins when higher speeds are not necessary. But its IP just works with RocketIO. - I am wondering if it's possible to implement it with diferrential pins other than RocketIO? - Does anybody know another pr...

I am using for the first time a Xilinx RocketIO module (I have years of FPGA experience though); normally I prefer to explicitly write on my code all the instatiations. Manual UG196 says:" The RocketIO GTP Transceiver Wizard is the preferred tool to generate a wrapper to instantiate a GTP_DUAL primitive." Any experience and advice about coding vs wizard in the case of RocketIO ? My app...

I'm connecting a V2Pro Rocket IO to a Agilent optical interface and am having problems getting the RocketIO receiver to reset properly and generate the correct data. The design originally used a Vitesse serial parallel interface chip and that worked fine. Since we have a spare RocketIO, we'd like to use it instead of the Vitesse chip. I'm running the link at 1062.5 Gbit/sec, so the refe

Is it just me or is the documentation for the RocketIO (MGT) for the Xilinx Virtex4 very bad? I'm trying to find duty cycle requirements for the MGT clock. Is it OK to use a clock with a 40% duty cycle? Also, if anyone can point me to some better RocketIO (MGT) documentation for the hardware guys I'd appreciate it. I already have ug076. Thanks, Dale

Dear all, I'm new to RocketIO and would appreciate any guidance from a hw design perspective. I am currently doing schematics for an application specific development board and trying to work through the various demands from the datasheets and app notes, for example, the fact that it seems to need three additional LDO power supplies?!? Any hints and tips would be useful. TIA --...

Hi, We are using RocketIO (1GHz Fibre Channel) in 32-bit mode in a Virtex-II Pro 50. We are using the CUSTOM_GT and believe that all the attributes are set correctly. The problem we are having is in our simulations. When data is received it seams that the Comma character is mis-aligned. According to the documention, this can happen and the signal RXREALIGN will indicate when re-alignme...
