My application consists of connecting HMC661 with Xilinx RF SOC ADC (ZCU111 board) with sampling at 2GSPS. The ADC has Vcm of 1.25V. But I want ADC and HMC661 connected DC coupled.
HMC661 datasheet says that Vob pin can have voltage between 1 to 3 V and Vcm according to formula in datasheet becomes +-0.5V.
If I want to have 1.25V offset on HMC661 outputs, what can I do to connect it with ADC with Vcm of 1.25V?
