Stratix GX FPGA Family
December 2004, ver. 2.2
Data Sheet
Introduction
The Stratix
®
GX family of devices is Altera’s second FPGA family to
combine high-speed serial transceivers with a scalable, high-performance
logic array. Stratix GX devices include 4 to 20 high-speed transceiver
channels, each incorporating clock data recovery (CDR) technology and
embedded SERDES capability at data rates of up to 3.1875 gigabits per
second (Gbps). These transceivers are grouped by four-channel
transceiver blocks, and are designed for low power consumption and
small die size. The Stratix GX FPGA technology is built upon the Stratix
architecture, and offers a 1.5-V logic array with unmatched performance,
flexibility, and time-to-market capabilities. This scalable,
high-performance architecture makes Stratix GX devices ideal for
high-speed backplane interface, chip-to-chip, and communications
protocol-bridging applications.
