Notes to
(1) Using the L dividers available in ATX PLLs.
(2) For improved jitter performance, Altera strongly recommends using the refclk pins of the transceiver block located immediately below the 10G
(3) For more information, refer to the Input Reference Clock Source table in the

Stratix IV GX and GT devices contain calibration circuits that calibrate the OCT
resistors and the analog portions of the transceiver blocks to ensure that the
functionality is independent of process, voltage, or temperature variations.
