Transceiver jitter perfomances of Arria II - GX

[sreevenkjan]

Hi All,

I am using arria II GX : EP2AGX45DF29I3 fpga in my porject. I referred the datasheet of arria II GX and saw the transceiver jitter performances of the GX series fpga's for different protocols. However I could not find jitter performance for protocol "Basic" at a datarate of 6.275 Gbps for GX series. Does anybody have any information regarding the transceiver jitter performance of arria II GX fpga at similar datarate??

I am trying to find a way of reducing the jitter. So my other question is if this fpga is suited and recommended for such a high speed electronic design??

regards,
Sreeni

Hi All,

I found some information from the Arria II-GX data sheet regarding Transmitter jitter based on refclk frequency. I have attached two images which are screenshots of the information on the datasheet. The first image is a screen shot of the transmitter specifications and the other image tells us the formula to calculate jitter at given refclk frequency.





My question is : Could you tell me what does this condition column such as 10KHz to 20Mhz mean or refer to??

Based on the formula provided in the image 2, if my ref clk is 25MHz then jitter would be about 6ps??

regards,
