Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a simplified UTMI interface. Currently doesn t do any error checking in the RX section [should probably check f

Bit stuffing is used for various purposes, such as for bringing bit streams that do not necessarily have the same or rationally related bit rates up to a common rate, or to fill buffers or frames. The location of the stuffing bits is communicated to

In data transmission and telecommunication, bit stuffing (also known—uncommonly—as positive justification) is the insertion of noninformation bits into data. Stuffed bits should not be confused with overhead bits. Bit stuffing is used for variou
