Altera Corporation (NASDAQ:ALTR) today announced its Stratix®
III FPGAs support Serial Gigabit Media Independent Interface (SGMII) on
its LVDS I/Os. Offering interface speeds of 1.25 Gbps and meeting SGMII’s
stringent jitter performance requirements, Stratix III LVDS I/Os support
triple-speed Ethernet (10/100/1000 Mbps) interfaces without
transceivers. Stratix III FPGAs are the industry’s
first programmable logic devices able to support Gigabit Ethernet SGMII
on LVDS pins, offering lower costs, lower power and more interfaces per
device.
The SGMII I/Os featured in Stratix III FPGAs allow the device to connect
to Gigabit Ethernet ports through small form-factor pluggable (SFP)
optical modules. Using Stratix III FPGA’s LVDS
channels, customers can integrate a large number of Gigabit Ethernet
channels in high-port-count applications, such as 96-port SGMII switches.
“Stratix III FPGAs were designed to deliver
tremendous value to customers with an unmatched combination of low
power, high performance and high density,”
said David Greenfield, senior director of product marketing, high-end
products, at Altera Corporation. “The high
data rate speeds and low jitter performance offered by Stratix III FPGA’s
LVDS I/Os provide wireline applications a cost-effective SGMII Gigabit
Ethernet interface.”
Stratix III FPGA LVDS channels support Gigabit Ethernet SGMII as a
result of the architecture’s low jitter
performance, dynamic phase aligner (DPA) and soft clock-data recovery
(CDR) mode. Soft-CDR, which is implemented in the programmable fabric as
IP, supports SGMII by extracting the clock out of the clock-embedded
data.
Availability
Altera’s Stratix III FPGAs, offering Gigabit
Ethernet SGMII connectivity on its LVDS I/Os, are available now. To view
