This user guide provides details about the Arria

10 transceiver physical (PHY) layer architecture, PLLs,

clock networks and transceiver PHY IP. It also provides protocol specific implementation details and

describes features such as reset controller, and dynamic reconfiguration.

Altera’s Arria 10 devices offer up to 96 transceiver channels with integrated advanced high speed analog

signal conditioning and clock data recovery techniques for chip-to-chip, chip-to-module, and backplane

applications.

The Arria 10 GX and SX devices have GX transceiver channels that can support data rates up to 17.4 Gbps

for chip-to-chip applications and 16.0 Gbps for backplane applications.

The Arria 10 GT devices have up to 16 GT transceiver channels, that can support data rates up to 28.3

Gbps for short reach chip-to-chip and chip-to-module applications. Additionally, the GT devices have GX

transceiver channels that can support data rates up to 17.4 Gbps for both chip-to-chip and backplane

applications. If all 16 GT channels are used in GT mode, then the largest GT devices also have up to 72

GX transceiver channels.

The Arria 10 transceivers support reduced power modes with data rates up to 11.3 Gbps (chip-to-chip)

and 10.3125 Gbps (backplane) for critical power sensitive designs. In GX devices that have transceivers on

both sides of the device, each side can be operated independently in standard and reduced power modes.

You can achieve transmit data rates below 611 Mbps and receive data rates below 1.0 Gbps with oversam‐

pling.

(1)

To operate GX transceiver channels at designated data rates in standard and reduced power modes, apply

the corresponding core and periphery power supplies. Refer to the Arria 10 Device Datasheet for more

details.

(2)

The Transmitter minimum operational data rate is 611 Mbps. For Transmitter data rates less than 611

Mbps, oversampling must be applied at the Transmitter.

(3)

The Receiver minimum operational data rate is 1.0 Gbps. For Receiver data rates less than 1.0 Gbps,

oversampling must be applied at the Receiver.
