5.6.5. Differential Receiver in Intel® Arria® 10 Devices

The receiver has a differential buffer and I/O PLLs that you can share among the transmitter and receiver, a DPA block, a synchronizer, a data realignment block, and a deserializer. The differential buffer can receive LVDS, mini-LVDS, and RSDS signal levels. You can statically set the I/O standard of the receiver pins to LVDS, mini-LVDS, or RSDS in the Intel® Quartus® Prime software Assignment Editor.

Note: The PLL that drives the LVDS SERDES channel must operate in integer PLL mode. You do not need a PLL if you bypass the deserializer
Table 64.  Dedicated Circuitries and Features of the Differential Receiver
Dedicated Circuitry / Feature Description
Differential I/O buffer Supports LVDS, mini-LVDS, and RSDS
SERDES Up to 10-bit wide deserializer
Phase-locked loops (PLLs) Generates different phases of a clock for data synchronizer
Data realignment (Bit slip) Inserts bit latencies into serial data
DPA Chooses a phase closest to the phase of the serial data
Synchronizer (FIFO buffer) Compensate for phase differences between the data and the receiver’s input reference clock
