Dear All:

Does anyone know How to do Mass product test of USB phy ?
We use 93000 test machine . I want to test stand-alone USB phy (1.1)

Thanks
 

for USB 2.0 PHY

use internal look back test ..
digital send out USB singal and receive from anoth PHY
chipset have many USB port ..
you can not check eye pattern in MASS production ..

for USB 1.1 PHY
standard IO　test .. USB　1.1 very slow ..
and we don't check Tr/Tf or cross-point by Mass production
