Hi All,
I also found chips on the internet and played with the FTDI245
chips.(works perfect.)
But the FTDI and Chip45 are USB2.0 full-speed devices.(max 12Mbps) I
was looking at USB2.0 hi-speed devices. (max 480Mbps)
I need the speed to make a JTAG programmer/ Boundry scan controller.
I needed speed that is around 100Mbps.(TCK) It's possible to make
this with slower speeds devices but I want to design this as fast
and best possible.
So for my application I don't realy need an AVR device.
I can use the Data lines from USB device for controlling the JTAG lines.
Ofcourse make a safety circuit so I don't blow up the USB device when
connected to a external JTAG device.
Does anyone know if these kind of chips are available?
(same kind of interface as the FTDI245 chips)
Thanks,
Greetings,
Pascal
