LMX2582: about registers

Part Number: LMX2582

HI all,

I have some questions about registers of LMX2582 as follows;

1. R0[4] of Figure 22 is "1" as constant number, but according to Table 5  R0 Register Field Descriptions, R0[4] is ACAL_EN.
    Which is correct?

2. R7[12] of Figure 22 is "04". is it "0"?

3. R30[ 0] of Figure 22 is "0", but according to Table 25. R30 Register Field Descriptions, R30[0] is VCO_2X_EN.
    Does LMX2582 support VCO doubler?

4. R46[5] is MASH_EN, but I cannot find the setting screen in the TICS Pro.
    Should I set it on the RAW REGISTERS setting screen of TICS Pro?

5. R46[4]  of Figure 22 is "1" as constant, but TICS Pro sets it to "0". Also according to LMX2952 datasheet, R46[4] is "0".
    Which is correct?
 
Regards,
Toshi

    Hi Toshi-san,
    1. This is a configurable bit called ACAL_EN.
    2. Correct, it it "0".
    3. LMX2582 datasheet RevB has already fixed this error. This bit is "0" in LMX2582.
    4. This bit should be a constant and should be equal to "1".
    5. This bit should be "0".

    Thank you for the information, we will fix these errors asap.
