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.

SFP+/SFP, XFP, CXP, QSFP/QSFP28, CFP/CFP2/CFP4

Cable Driving Support

SFP+ Direct Attach, PCI Express over cable, eSATA

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

Variable Gain Amplifier Optimizes the signal amplitude prior to the CDR sampling and operates in fixed and adaptive modes

Altera Digital Adaptive Parametric Tuning (ADAPT)

Fully digital adaptation engine to automatically adjust all link equalization parameters—including CTLE, DFE, and variable gain amplifier blocks—that provide optimal link margin without intervention from user logic

Precision Signal Integrity Calibration Engine (PreSICE)

Hardened calibration controller to quickly calibrate all transceiver control parameters on power-up, which provides the optimal signal integrity and jitter performance

Advanced Transmit (ATX) PLL

Low jitter ATX (LC tank based) PLLs with continuous tuning range to cover a wide range of standard and proprietary protocols

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
