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.
|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|
|On-chip termination (OCT)||100 Ω in LVDS I/O standards|
