This is Next 3V1 revision of LM399 ADR1399KHZ based reference board, when i made my last version i received quite few small feedback form users , So I have again made few improvements in This forth version over Third reversion accumulating those suggestions. Fist improvements is, Board has LT3042 Ultralow Noise, Ultrahigh PSRR RF Linear Regulator To Supply 15V to the ADR1399 and LT1001 , This…
For new FPGA SoC related project, and i will be using Avnet MicroZed Zynq SOM board. But Avnet microZed Board has two 100 Pin fine pitch connectors for expansion, Which is impractical for prototyping so i decided to make my own breakout board. Finding Avent microzed GPIO breakout was little hard and official board has same VCCIO regulator for all banks and avnet board also does not have…
