1. Introduction
The Stratix II GX family of devices is Altera’s third generation of FPGAs
to combine high-speed serial transceivers with a scalable,
high-performance logic array. Stratix II GX devices include 4 to 20
high-speed transceiver channels, each incorporating clock and data
recovery unit (CRU) technology and embedded SERDES capability at
data rates of up to 6.375 gigabits per second (Gbps). The transceivers are
grouped into four-channel transceiver blocks and are designed for low
power consumption and small die size. The Stratix II GX FPGA
technology is built upon the Stratix II architecture and offers a 1.2-V logic
array with unmatched performance, flexibility, and time-to-market
capabilities. This scalable, high-performance architecture makes
Stratix II GX devices ideal for high-speed backplane interface,
chip-to-chip, and communications protocol-bridging applications.
