Discussion - Hardware / FT600/601 Question about maximum data rate (practical)
« on: February 07, 2018, 07:04:30 PM »
Hi. I have a proposal for a project where I have to manage the samples of an ADC of 8 bits @ 100 MHz. I have to deliver the samples to a PC quite fast, so I think that the FT600/601 would be a nice choice for that. The thing is that I've used in the past the FT232H with the FIFO sync mode (60 MHz clk FIFO) and the bottleneck where in FTDI D2xx drivers...they limited my data transfer speed much below the 480 Mbits of USB 2.0 (and in Windows worked faster than Linux, FTDI support said in that moment).
So I write this post to ask you if you (people of FTDI) have a practical (not the theoretical 5Gbps) number of the transfer rate in MB/s with the FT600/601 working in SYNC FIFO using D3xx drivers. My application needs 100 Ms/s maximum but if I use the 32 bits parallel FIFO I only would need 25 Ms/s. I would like to have a good margin to be sure that I don't loose samples (as in my FT232H old project)....
Thanks and regards
