The Stratix IV transmitter has a dedicated circuitry to provide support for LVDS
signaling. The dedicated circuitry consists of a differential buffer, a serializer, and left
and right PLLs that can be shared between the transmitter and receiver. The
differential buffer can drive out LVDS, mini-LVDS, and RSDS signaling levels. The
serializer takes up to 10 bits wide parallel data from the FPGA fabric, clocks it into the
load registers, and serializes it using shift registers clocked by the left and right PLL
before sending the data to the differential buffer. The MSB of the parallel data is
transmitted first.
When using emulated LVDS I/O standards at the differential transmitter, the
SERDES circuitry must be implemented in logic cells but not hard SERDES.

Busy signal that is asserted high when the PLL calibration occurs.
Asynchronous reset to the DPA circuitry and FIFO. The minimum pulse
width requirement for this reset is one parallel clock cycle. This signal
resets DPA and FIFO blocks.
Asynchronous reset to the FIFO between the DPA and the data realignment
circuits. The synchronizer block must be reset after a DPA loses lock
condition and the data checker shows corrupted received data. The
minimum pulse width requirement for this reset is one parallel clock cycle.
This signal resets the FIFO block.
Asynchronous reset to the data realignment circuitry. The minimum pulse
width requirement for this reset is one parallel clock cycle. This signal
resets the data realignment block.
