PMA Features
Intel® Arria® 10 transceivers provide exceptional signal integrity at data rates up to 25.8 Gbps. Clocking options include ultra-low jitter ATX PLLs (LC tank based), clock multiplier unit (CMU) PLLs, and fractional PLLs.
Each transceiver channel contains a channel PLL that can be used as the CMU PLL or clock data recovery (CDR) PLL. In CDR mode, the channel PLL recovers the receiver clock and data in the transceiver channel. Up to 80 independent data rates can be configured on a single Intel® Arria® 10 device.

Transmit Pre-Emphasis |
4-tap transmit pre-emphasis and de-emphasis to compensate for system channel loss |
Continuous Time Linear Equalizer (CTLE) |
Dual mode, high-gain, and high-data rate, linear receive equalization to compensate for system channel loss |
Decision Feedback Equalizer (DFE) |
7-fixed and 4-floating tap DFE to equalize backplane channel loss in the presence of crosstalk and noisy environments |

Fractional PLLs |
On-chip fractional frequency synthesizers to replace on-board crystal oscillators and reduce system cost |
Digitally Assisted Analog CDR |
Superior jitter tolerance with fast lock time |
Dynamic Partial Reconfiguration |
Allows independent control of the Avalon memory-mapped interface of each transceiver channel for the highest transceiver flexibility |
Multiple PCS-PMA and PCS-PLD interface widths |
8-, 10-, 16-, 20-, 32-, 40-, or 64-bit interface widths for flexibility of deserialization width, encoding, and reduced latency |
