6.2.4. OCT Intel® FPGA IP Signals

Table 60.  Input Interface SignalsIn the table, n represents the number of OCT blocks defined in the Number of OCT blocks parameter. The width of each signal is one per OCT block.
Signal Name Direction Description
rzqin[n:0] Input

Input connection from RZQ pad to the OCT block. RZQ pad is connected to an external resistance. The OCT block uses impedance connected to the rzqin port as a reference to generate the calibration code.

This signal is available for power-up and user modes.
calibration_request[n:0] Input

Set to 1 to request the OCT block to start calibration. Hold the signal for at least 2 ms or until ack_recal is set to 1.

This signal is only available for user mode.
ack_recal[n:0] Output

When set to 1 indicates OCT block is ready for calibration. There should be no calibration activities from the core to the OCT block until this signal is asserted for every calibration request.

This signal is only available for user mode.
ser_data_n Output

Transfer serial output calibration data from OCT block to I/O buffer.
