Part Number: AFE7222 Other Parts Discussed in Thread: AFE7225EVM , TRF370333 Dears.
customer is developing AFE7222.
AFE7222 DAC has a current output, but use Voltage input GRF6413, need Current to Voltage with Common voltage tuning. Use Transformer or…
Thanks Ken,
The attenuation looked wrong, because the cap accross R2 was not shown (pseudo DC). Unfortunately we do use a DC output, so the
AC short circuit will not help.
I will revisit the complete DAC / modulator selection. In the mean time I will…
Other Parts Discussed in Thread: DAC5688 , TRF370333 Hi.
I got ACPR decreasing problem using DAC5688.
Fdata=122.88MHz
NCO=15.36MHz/138.32MHz
FDAC=491.52MHz
PLL off
X4 interpolation
All data is measured data at moduler TRF370333 ouput
As captured…
The TRF3703 provides improved performance compared to the TRF3701/2, specifically in the linearity parameter. There is another advantage that the TRF370333 device operates at a 3.3V common mode that mates seamlessly with the DAC568x family. There is a…
