I have two question about TUSB542 LFPS support.
I am now making USB TRX with FPGA SERDES blocks.
Super speed communication is no trouble, but LFPS negotiation is a little bit difficult.
So if some TI product support LFPS negotiation with host, I am very happy to use.
1. When device is U3 mode and TUSB542 receive LFPS (Wakeup), TUSB542 reply something to host automatically(ex: polling or others)?
2. Can device get the information when TUSB542 receive LFPS(Wakeup or others)?
or something other TI chip may support this kind of LFPS negotiation?
Ex: SN65LVPE502CP is better for me?
Thank you for your cooperation.
With Best Regards.
