Frequency requirement for IFCLK? 5MHz~ 48MHz?

[Anonymous]

Hi!

   

For some reason,

   

I can't use FPGA in my project where I need to use 68013A to conduct USB data transfer.

   

I use STM32 instead of the FPGA as the control logic of CY7C68013A.

   

then , MUST I feed the pin IFCLK  in frequency between 5MHz and 30MHz?

   

Looking forward to an instant reply!

   

Thank you!

 HI,

       

If IFCLK pine will be driven by an external clock, then it can be at any frequency between 5 MHz and 48 MHz. it must be free running at a minimum frequency of 5 MHz. It is clearly mentioned in Technical reference manual in section 9.2.3.
