Voltage Reference Capabilities
Stratix II GX transceivers provide voltage reference and bias circuitry. To
set up internal bias for controlling the transmitter output driver voltage
swings, as well as to provide voltage and current biasing for other analog
circuitry, the device uses an internal bandgap voltage reference of 0.7 V.
An external 2-KΩ resistor connected to ground generates a constant bias
current (independent of power supply drift, process changes, or
temperature variation). An on-chip resistor generates a tracking current
that tracks on-chip resistor variation. These currents are mirrored and
distributed to the analog circuitry in each channel.
For more information, refer to the
chapter in volume 1 of the Stratix II GX Handbook.
