EVREF0102A

The EVREF0102A is the analog power module for the Zynq UltraScale+ RFSoC characterization kit. The EVREF0102 analog power module provides an ultra low-noise power supply for the high-speed data converters.  

The EVREF0102A employs five high efficiency step-down switched-mode power modules with integrated inductors. MPM3833C is a 6V, 3A, ultra-small step-down power module, and the MPM3683-7 is a 16V, 8A power module. Both power modules feature integrated protection functions including OCP, OVP, and UVP. The EVREF0102A offers significant efficiency improvement compared to a traditional LDO solution. The EVREF0102A analog power module also achieves ultra-low noise levels to meet the specifications of Xilinx high-speed data converters by leveraging forced continuous conduction mode (FCCM) operation and implementing post-passive filters. CLC passive filters are utilized for the two most sensitive ADC and DAC rails, and capacitive filters are utilized for the rest of power rails.
