User Guide
Transceiver Calibration Functions
Enable offset cancellation On
When enabled, the Transceiver Reconfiguration Controller
includes the offset cancellation functionality. This option is always
on. Offset cancellation occurs automatically at power-up and runs
only once.
Enable duty cycle calibration On/Off
For Arria V devices, when enable, DCD calibrates for duty cycle
distortion caused by clock network skew. DCD calibration runs
once during power up. You should enable this option for protocols
running at greater than 4.9152 Gbps.
Enable PLL calibration On/Off
When enabled, an algorithm that improves the signal integrity of
the PLLs is included in the Transceiver Reconfiguration Controller
IP Core. This feature is only available for Stratix V devices.
Create optional calibration
status ports
On/Off
When you turn this option On, the core includes
tx_cal_busy
and
rx_cal_busy
ports. These signals are asserted when
calibration is active.
Analog Features
Enable Analog controls On/Off
When enabled, TX and RX signal conditioning features are
enabled.
Enable EyeQ block On/Off
When enabled, you can use the EyeQ, the on-chip signal quality
monitoring circuitry, to estimate the actual eye opening at the
receiver. This feature is only available for Stratix V devices.
Enable decision feedback
equalizer (DFE) block
On/Off
When you turn this option On, the Transceiver Reconfiguration
Controller includes logic to perform DFE
Enable adaptive equalization
(AEQ) block
On/Off
When enabled, the Transceiver Reconfiguration Controller
includes logic to perform AEQ. This feature is only available for
Stratix V devices.
Reconfiguration Features
Enable channel/PLL
reconfiguration
On/Off
When enabled, the Transceiver Reconfiguration Controller
includes logic to include both channel and PLL reconfiguration.
Enable PLL reconfiguration
support block
On/Off
When enabled, the Transceiver Reconfiguration Controller
includes logic to perform PLL reconfiguration.
