Is there a combination of VCCHTX and Vcm in Stratix® II GX that can be used across the entire range of operation?

Environment

  • Stratix® II GX FPGA
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Yes.  But in the current Quartus II software version, VCCHTX is required to be 1.2V for a Vcm of 0.6V for running the Stratix II GX transceiver between 622Mbps – 3.125Gbps.  This will be fixed in Quartus II version 6.0SP1 so that VCCHTX can be 1.5v for the Vcm of 0.6V for the data range 622Mbps-6.375Gbps. In the current Quartus II version, the users can set VCCHTX to 1.2V for the data range 622 Mbps - 3.125Gbps to get through the compilation successfully.
