Arria II Device Architecture
July 2012 Altera Corporation Arria II Device Handbook Volume 1: Device Interfaces and Integration
■ Arria II GX devices have dedicated configuration banks at Bank 3C and 8C, which
support dedicated configuration pins and some of the dual-purpose pins with a
configuration scheme at 1.8, 2.5, 3.0, and 3.3 V. For Arria II GZ devices, the
dedicated configuration pins are located in Bank 1A and Bank 1C. However, these
banks are not dedicated configuration banks; therefore, user I/O pins are available
in Bank 1A and Bank 1C.
■ Dedicated

pin per I/O bank to allow voltage-referenced
I/O standards. Each I/O bank can operate at independent V

levels.
High-Speed LVDS I/O and DPA
■ Dedicated circuitry for implementing LVDS interfaces at speeds from 150 Mbps to
1.25 Gbps
■ R
D
OCT for high-speed LVDS interfacing
■ DPA circuitry and soft-CDR circuitry at the receiver automatically compensates for
channel-to-channel and channel-to-clock skew in source-synchronous interfaces
and allows for implementation of asynchronous serial interfaces with embedded
clocks at up to 1.25 Gbps data rate (SGMII and GbE)
■ Emulated LVDS output buffers use two single-ended output buffers with an
external resistor network to support LVDS, mini-LVDS, BLVDS (only for
Arria II GZ devices), and RSDS standards.
Clock Management
■ Provides dedicated global clock networks, regional clock networks, and periphery
clock networks that are organized into a hierarchical structure that provides up to
192 unique clock domains
■ Up to eight PLLs with 10 outputs per PLL to provide robust clock management
and synthesis
■ Independently programmable PLL outputs, creating a unique and
customizable clock frequency with no fixed relation to any other clock
■ Inherent jitter filtration and fine granularity control over multiply and divide
ratios
■ Supports spread-spectrum input clocking and counter cascading with PLL
input clock frequencies ranging from 5 to 500 MHz to support both low-cost
and high-end clock performance
■ FPGA fabric can use the unused transceiver PLLs to provide more flexibility
