> A BoW PHY slice either transmits or receives 16 bits of data between die. The BoW is a source-synchronous PHY and each transmitting PHY slice transmits a complementary clock signal CLK+ and CLK- with the data. A BoW PHY optionally has two additional wires designated FEC (for Forward Error Correction) and AUX, for other optional functions such as Data Bus Inversion (DBI).
