LMX2594: Full Assist

Part Number: LMX2594

Hello,

My customer considers using the LMX2594 with Full Assist below.

Is it correct that the read back values of R110, R111 and R112 in Step 2 read different values for each device?

Thank you.

    Hi JH,

    R111/R112 can be different from device to device. The internal calibration chooses for each device the correct Capcode and ampitude setting. Those can vary over units.

    R110 should be fairly stable. It contains the VCO band selection (rb_VCO_SEL), which should be stable, unless you operate at a border between 2 bands. The second field in that register is the lock detect status which ideally always reads back 2 for "locked".

    Please let me know which bits of R110 are changing and i can check it in more detail.

    regards,

    Julian
