KL27 - Crystal-less USB - Does it support host configuration?

Hi,

 

For a cost sensitive solution where it requires two USB ports (1 x Host and 1 x Device), I am considering of using 2x KL27 which has the crystal-less USB feature. This way i can save the overall system cost by avoiding the external clock(s). However, as I understand from the app note AN4905, the crystal-less feature with the clock recovery circuit (to maintain the accuracy of the clocking) supports full-speed device configuration only. Can this be achieved for host (OTG) as well? If not what are the alternatives?

Thanks.

 

Regards,

DJ
