LMX2594: LMX2594 Register Programming

Part Number: LMX2594


Regarding the LMX2594 registers, I'd like to know:

1. Is there an officially recommended time order for register configuration? For example, power on first, then set the frequency and power, then lock, then read back. Is there a more specific recommended time order, or configuration logic, or sequence? I'd like to refer to this so I can more clearly tell embedded developers which register to configure first.

2. I noticed that R0 through R112 all support readback. If readback is enabled, can specific registers be selectively read back?

3. I noticed that the register parameters OUT_MUTE and OUT_FORCE need to be configured together. Is there a specific time order for configuring them?

  • Hi Qin,

    Programming sequence is available in the datasheet, except that step 3 is not necessary, we will remove this step in next datasheet revision. 

    Register read back does not have a sequence, you can read back any register in any order. 

    There is no programming sequence requirement for OUT_MUTE and OUT_FORCE.
