6.3.1 HS Receive Equalization

The DPHY440 supports three levels of receive equalization to compensate for ISI loss in the channel. These three levels are 0 dB, 2.5 dB, and 5 dB at 750MHz. The equalization level used by the DPHY440 is determined by the state of the EQ/SCL pin at the rising edge of RSTN. If necessary, the receiver equalization level can also be set through writing to the RXEQ register via the local I2C interface
