Devices with SMSC marking
As of 2012, SMSC is part of Microchip, and Microchip sells parts that were previously manufactured by SMSC, such as the ULPI PHY chips and USB HUBs.
Now, the curious thing is, that since I have moved my production of one product to the far east, I have received boards with SMSC chips on them (USB2513B), with a date code of "1622", while a previous production run had "1543" or something on them, with the Microchip logo (USB2513B). So, in summary: 2016 chips from SMSC and 2015 chips from Microchip. The ones from 2015 were bought through "Microchip Direct", and the 2016 chips came from a supplier in China.
Is this at all possible, or are we looking into counterfeited chips?
