[Discuss-gnuradio] Question about IF frequency to send

Hello,

We’re implementing a CDMA base station wholly within the FPGA on the N210. I have a question regarding IF frequency.  In the dsp_core_tx module the IQ data is going through some interpolation and then a cordic. Is the cordic used to upconvert to some IF before being sent to the DAC? If so, what is the IF frequency into the DAC?

Thank you.
