7.5 LMH1219 Register Map
The LMH1219 register map is divided into three register pages. These register pages are used to control different aspects of the LMH1219 functionality. A brief summary of the pages is shown below:
- Share Register Page: This page corresponds to global parameters, such as LMH1219 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, CDR settings, and output interrupt overrides. Access this page by setting Reg 0xFF[2:0] = 100’b.
- CableEQ/Drivers Register Page: This page corresponds to IN0 Cable EQ and both OUT0 and OUT1 driver output settings. Access this page by setting Reg 0xFF[2:0] = 101’b.
For typical device configurations and proper register reset sequencing, reference the appropriate sections of the LMH1219 Programming Guide.
Please note the following about the LMH1219 default register values in the register map:
- Default register values were read after power-up with no active inputs applied to IN0 or IN1.
- Default register values for Reserved "Read-Only" bits may vary dynamically from part to part.
