7.5 LMH1226 Register Map
The LMH1226 register map is divided into three register pages. These register pages are used to control different aspects of the LMH1226 functionality. A brief summary of the pages is shown below:
- Share Register Page: This page corresponds to global parameters, such as LMH1226 device ID and LOCK_N status configuration. This is the default page at start-up.
- CTLE/CDR Register Page: This page corresponds to IN1 PCB CTLE, input and output mux settings, internal CDR settings, and output interrupt overrides. Access this page by setting Reg 0xFF[2:0] = 100’b.
- Drivers Register Page: This page corresponds to both OUT0 and OUT1 driver output settings. Access this page by setting Reg 0xFF[2:0] = 101’b.
Please note the following about the LMH1226 default register values in the register map:
- Default register values were read after power-up with no active inputs applied to IN1.
- Default register values for Reserved "Read-Only" bits may vary dynamically from part to part.
