Introduction and overview

...

• TRAINING_REQUEST_OUT - output : Active high. The IP Core informs that it requires an external transmitter device to send continuously a specific value – called “DES_TrainingValue” to the deserializers (receivers) being part of the IP Core. TRAINING_REQUEST_OUT goes back low after the calibration (bit & word alignment) process is complete (see CALIB_DONE output.

• TRAINING_ACK_IN - input : When high, the transmitter informs that it received the request for receiver calibration, and it’s currently sending the required training value.

• TRAINING_REQUEST_IN - input : Active high. If the IP Core is used as transmitter, it must send the expected “SER_TrainingValue” to the receiver. This is the training request signal coming from the external receiver device.
