7.5 Register Maps
The LMH1208 register map is divided into three register pages. These register pages are used to control different aspects of the LMH1208 functionality. A brief summary of the pages is shown below:
- Share Register Page: This page corresponds to global parameters, such as LMH1208 device ID and SD_N status configuration. This is the default page at start-up. Access this page by setting Reg 0xFF[2:0] = 000’b.
- CTLE Register Page: This page corresponds to IN0 PCB CTLE, output mux settings, and output interrupt overrides. Access this page by setting Reg 0xFF[2:0] = 100’b.
- Driver Register Page: This page corresponds to OUT0, SDI_OUT1, and SDI_OUT2 driver output settings. Access this page by setting Reg 0xFF[2:0] = 101’b.
For the complete register map, typical device configurations, and proper register reset sequencing, refer to the LMH1228 and LMH1208 Programming Guide (SNAU206).
