7.6.1 Register Map

The ADS58J64 registers are organized on different pages depending on their internal functions. The pages are accessed by selecting the page in the master pages 11h–13h. The page selection must only be written one time for a continuous update of registers for that page.

There are six different SPI banks (shown in Figure 7-32) that group together different functions:

  • GLOBAL: contains controls for accessing other SPI banks
  • DIGTOP: top-level digital functions
  • ANALOG: registers controlling power-down and analog functions
  • SERDES_XX: registers controlling JESD204B functions
  • CHX: registers controlling channel-specific functions, including DDC
  • ADCXX: register page for one of the eight interleaved ADCs
