circuitry affected by each signal.
Arria GX devices use the calibration block to calibrate OCT for the PLLs, and their
associated output buffers, and the terminating resistors on the transceivers. The
calibration block counters the effects of process, voltage, and temperature (PVT). The
calibration block references a derived voltage across an external reference resistor to
calibrate the OCT resistors on Arria GX devices. You can power down the calibration
block. However, powering down the calibration block during operations can yield
transmit and receive data errors.
This section describes the clock distribution in an Arria GX transceiver channel and
the PLD clock resource utilization by the transceiver blocks.
Transceiver Channel Clock Distribution
Each transceiver block has one transmitter PLL and four receiver PLLs.
