Stratix GX Transceivers
accurately tracked by the internal bias circuit. Moreover, the reference
voltage and internal resistor bias current is generated and replicated to
the analog circuitry in each channel.
Hot-Socketing Capabilities
Each Stratix GX device is capable of hot-socketing. Because Stratix GX
devices can be used in a mixed-voltage environment, they have been
designed specifically to tolerate any possible power-up sequence. Signals
can be driven into Stratix GX devices before and during power-up
without damaging the device. Once operating conditions are reached and
the device is configured, Stratix GX devices operate according to your
specifications. This feature provides the Stratix GX transceiver line card
behavior, so you can insert it into the system without powering the
system down, offering more flexibility.
Each Stratix GX transceiver block is designed to operate at any serial bit
rate from 500 Mbps to 3.1875 Gbps per channel. The wide, data rate range
allows Stratix GX transceivers to support a wide variety of standard and
future protocols such as 10-Gigabit Ethernet XAUI, InfiniBand, Fibre
Channel, and Serial RapidIO. Stratix GX devices are ideal for many high-
speed communication applications such as high-speed backplanes, chip-
to-chip bridges, and high-speed serial communications standards
support.
