USB Low-Full-High Speed Peripherals

Hi to everyone and thanks in advance for your help,

   

I'm creating an hardware FPGA design which use a FX2LP USB chip. I'm considering floating (not connecting to anything) the CLKOUT pin from my                                                  CY7C68013A-100AXI FX2LP, since I only use the bidirectional IFCLK pin (my custom firmware set CPUCS.1 = 1, setting this pin as three-state).

   

Since I'm a beginner, do you think there may be any problem I'm not considering, doing this operation? CLKOUT may be useful for something I don't know?

   

Thanks,

   

A.

 Hi,

   

You can safely float the CLKOUT pin. Youcan even disable the Clock output by writing into the CPUCS register.
