Arria II FPGAs: Cost-Optimized, Lowest Power 6G Transceiver FPGAs

The Arria® II GX device family is designed specifically for ease-of-use. The cost-optimized, 40-nm device family architecture features a low-power, programmable logic engine and streamlined transceivers and I/Os. Common interfaces, such as the Physical Interface for PCI Express® (PIPE) (PCIe®), Ethernet, and DDR3 memory are easily implemented in your design with the Quartus® II software, the SOPC Builder design software, and a broad library of hard and soft intellectual property (IP) solutions from Altera®. The Arria II GX device family makes designing for applications requiring transceivers operating at up to 6.375 Gbps fast and easy.

High-Speed Transceiver Features

Arria II GX devices integrate up to 16 transceivers on a single device. The transceiver

block is optimized for cost and power consumption. Arria II GX transceivers support the following features:

■ Configurable pre-emphasis and equalization, and adjustable output differential voltage

■ Flexible and easy-to-configure transceiver datapath to implement proprietary protocols

■ Signal integrity features

■ Programmable transmitter pre-emphasis to compensate for inter-symbol interference (ISI)

■ User-controlled five-stage receiver equalization with up to 7 dB of high-frequency gain

■ On-die power supply regulators for transmitter and receiver PLL charge pump and voltage-controlled oscillator (VCO) for superior noise immunity

■ Calibration circuitry for transmitter and receiver on-chip termination (OCT) resistors

■ Diagnostic features

■ Serial loopback from the transmitter serializer to the receiver CDR for transceiver physical coding sublayer (PCS) and physical media attachment (PMA) diagnostics

■ Parallel loopback from the transmitter PCS to the receiver PCS with built-in self test (BIST) pattern generator and verifier

■ Reverse serial loopback pre- and post-CDR to transmitter buffer for physical link diagnostics

■ Loopback master and slave capability in PCIe hard IP blocks

■ Support for protocol features such as MSB-to-LSB transmission in a SONET/SDH configuration and spread-spectrum clocking in a PCIe Configuration
