Calibration is done on each of the data (DDC_DIN) and DVALID signal pairs using the training pattern as specified in input Data Interface (DIN) Training Pattern. When calibration is successful, the Initialization will move on to initializing the first DLPA200.
The training pattern going into the SERDES on the transmit side is different than the pattern on the receive SERDES. On the receive side the value should be “0100”. However, this could translate to “0010” on the transmit side. Please see input Data Interface (DIN) Training Pattern for more information. An improper training pattern could cause the part to not perform the commands correctly.
