A quick look at the latest product table for the Xilinx Zynq UltraScale+ RFSoC will tell you that the sample rate for the devices’ RF-class, 14-bit DAC has jumped to 6.554Gsamples/sec, up from 6.4Gsamples/sec. I asked Senior Product Line Manager Wouter Suverkropp about the change and he told me that the increase supports “…an extra level of oversampling for DOCSIS3.1 [designers]. The extra oversampling gives them 3dB processing gain and therefore simplifies the external circuits even further.”
