Hello Guys,
Good day.
Our customer is asking if he can communicate to each chip individually by using only the CSB lines to select one chip, or the other, or does the SPI bus have to be physically disconnected from one device (via the mechanical switches) while he talk to the other?
He is trying to make a low-noise 15 GHz LO with 2 LMX2595's as in the TIDA document. He prefer to use the CSB lines over mechanical switches.
Thanks!
Art
